AlphaTheta has come out of the gate swinging with its release of the Omnis-Duo all-in-one DJ controller and Wave-Eight speaker today. These two products are the first under the company’s new moniker since changing it from Pioneer DJ, although both brand names are expected to coexist for now. The launch coincides with the NAMM event this week and it’s also the 30th anniversary of the landmark Pioneer CDJ-500.

Both the controller and speaker are brimming with connectivity and battery power, making them an appealing option for mobile DJs. Rekordbox is a necessity right now, either for direct play or file prep and the app comes bundled with the Omnis-Duo controller. Serato DJ Lite support is expected later this summer and the software should already be bundled with the product. The Wave-Eight is more flexible and can work just as well with any audio source that has an RCA output.

Omnis-Duo

The Omnis-Duo ($1,499) is built to be portable, but also packs in some high-end tech. It’s a 10-pound device with fairly reserved and minimal styling that the company says you can fit in a “good-sized” backpack given its 20 x 12 x 3-inch in size. There’s a two-channel mixer flanked by two jog wheels and eight performance pads under each, although those only work for hot cues and have white LED lighting only. On top you’ll find a touchscreen display with an XDJ-style workflow and both light and dark modes. The display is flat and not angled up for easier viewing.

AlphaTheta

You get essential controls for volume, EQ, playback, pitch and dedicated ones for beat jump and beat loop. There are also ones to select eight types of beat FX and six types of sound color FX from, but expect some touchscreen coordination to select which channel to apply to.

On the front edge you’ll find both 1/4-inch and 3.5mm stereo headphone jacks. The rear panel displays a wide selection of inputs for USB-A, SD cards and USB-C laptop input next to a USB-C charging port that lets you use either a power bank to top up the battery or an AC adapter. When fully charged we’re told you can expect around five hours of runtime and the system has an eco mode if things are looking grim.

As for wireless connections, there’s a novel Bluetooth input option. People can find the Omnis-Duo in their mobile device settings and connect. If they have files on the phone, the DJ should actually be able to select, load and play files in their set with effects and all. It’s not entirely clear yet, but the other option is likely just normal playback through the controller from a connected Bluetooth device. This is for one user at a time since multipoint is not supported. There's also a wireless output option for connecting to the Wave-Eight speaker using its SonicLink Bluetooth transmitter which connects to the RCA outputs.

And for Wi-Fi connectivity, you can take advantage of CloudDirectPlay to access cloud file storage through a wirelessly connected computer or mobile device running Rekordbox. Additionally, you can use Rekordbox Link Export to directly select and play tracks from a connected device running the app.

Wave-Eight

The Wave-Eight speaker isn’t quite part of a bundled release, it’s just a great pairing with the Omnis-Duo, given its portability, battery power and wireless capability. This speaker has an 8-inch driver and what the company calls a “Vortex Bass Accelerator” for its output. The 28-pound build includes an extendable handle and casters for luggage-style rolling, plus a couple of convenient grab handles for local lugging.

AlphaTheta

You can mount it on a stand with its pole socket, so it’s a proper PA speaker, and it’s IPX4 rated, so it’s good for the outdoors unless rain really starts coming down. There’s an onboard battery that should give you about eight hours of playtime on a charge and it takes about four hours or more of charging to get back to one hundred percent. Obviously you can use it as a powered-speaker all night long if there’s an outlet nearby.

What makes this speaker interesting is the removable AlphaTheta transmitter with SonicLink technology. Each speaker comes with a transmitter packed into a side panel. They have an RCA input and a USB-C cable. With one speaker, you take the transmitter out and connect it to an RCA output from your audio setup. Then return to the speaker and set it to connect wirelessly via SonicLink. Once connected that way, it should display a green light on the front panel, so you can confirm the status at a distance.

If you have a second speaker, you take that one’s transmitter and pop it into the first speaker via the USB-C port. That will transmit the audio to the second unit where you set that one to connect via SonicLink (and so on). The speakers support left and right for stereo delivery as well via a channel selector button on the back. 

To make things more interesting, each speaker has a variety of audio output settings which include Music, Music (Low Cut), Flat, Flat (Low Cut), Vocal and Subwoofer modes. This means each Wave-Eight speaker can be set as a top or sub. You can set one speaker to a low-cut setting and use another one as its subwoofer accompaniment if you like.

The SonicLink is said to provide a latency-free listening experience, so there shouldn’t be any delay and you can beat match by ear from the output. Of course you can also send audio to a single Wave-Eight via a normal Bluetooth signal and expand to more speakers as you would before. This time, however, you're subject to the normal Bluetooth signal's whims in terms of potential audio delays.

There’s an interesting thing about the Wave-Eight in that wired connections (aside from power) were not mentioned anywhere in the press release. You can use the speakers via Bluetooth or with the SonicLink transmitter from any device that has an RCA output, though. We’ve asked for clarification, but at this point we’re led to believe that it just supports wireless connections. We’re also still curious about the Bluetooth range for these devices, but expect that it falls within the normal range of about 30 feet.

AlphaTheta has chosen an interesting combo of high-end features, wireless connectivity and battery-powered portability for its premier offering. While they may not be cheap, there’s quite a lot built into both products to balance out the equation.

The Omnis-Duo all-in-one DJ controller ($1,499) and the Wave-Eight speaker ($899) are both available starting today.

It’s been over seven years since Apple found the “courage” to remove the 3.5mm headphone jack from the iPhone, in turn forcing wireless headphones into the limelight. To this day, listening to hi-res lossless music on a phone usually means a hunt for a rare handset with a 3.5mm jack or accepting your new dongle life. As if from nowhere, a new breed of wired headphone has emerged, and it promises audiophile quality on any phone with no need for a dongle. Of course there’s a marketing term to go with it: True Lossless Earphones (TLE).

You might not have heard of Questyle, but the company has been making hobbyist HiFi gear for years. Last November, the company tried something different with its NHB12 Lightning headphones. The IEM-style buds incorporate a digital audio converter (DAC) capable of handling Apple Music’s top-tier Hi-Res Lossless files (192kHz/24-bit). Ahead of CES this month, the company released a USB-C version — the $350 NHB15 — bringing its all-in-one hi-res digital headphone to almost every other phone, tablet or PC.

Two days after Questyle announced the NHB15, rival company Hidizs claimed that its own DAC-packing ST2 Pro model was the world’s first hi-res digital IEM. It’s not quite a trend yet, but expect a mini wave of similar products to follow and I’m not sure it matters who was first. What’s more interesting is that, with iPhones switching to USB-C and plug-and-play hi-res options on the table, all the ingredients are there for mini wired headphone revival — although I don’t think it would last and we’ll get to why later.

It’s worth noting that all these USB-C headphones have some sort of DAC in them, but rarely are they hi-res capable. “Hi-res” audio is a broad term, but here we’re following Apple’s own language, which is anything above 48kHz. In recent years, some HiFi companies have released USB-C cables with DACs in them that support higher resolutions. Queststyle and Hidizs are just taking it to the next logical conclusion by bundling everything together — which is what makes them more interesting to the casual (but audio curious) listener.

I’ve tried a fair few standalone DACs over my years here at Engadget and I appreciate the superior audio quality they provide, but I never found one I’d use while out and about. There are some that come close, like the fantastic DragonFly Cobalt by AudioQuest or the sleek Onyx by THX but they all require something between your phone and your headphones — by which time I’ll just reach for my best wireless set and be done. The NHB15 though, I could see myself using these on the regular.

The experience is no more complicated than connecting a regular 3.5mm set. The DAC isn’t invisible; at first you might think it was in-line, yoke-style media controls. In fact, if this had buttons on it that would both complete the illusion and add handy functionality, but for now it’s purely there to turn your music from zeros and ones into audible sound. LEDs let you know if you’re slumming it with lossy music (one illuminated) or living the true lossless life (two illuminated). It’s a minimal but effective approach.

Apple

Let’s ignore that the cheapest 3.5mm buds you can buy on Amazon are theoretically also truly lossless earphones, but TLE isn’t an entirely useless term. If it can become the equivalent of “UHD” but for USB-C headphones, with a minimum confirmed level of hi-res audio support — anything above Apple’s standard lossless (48kHz) perhaps, that’s useful enough.

Importantly, Questyle’s NHB15 does a good job with music. Listening via Qobuz, I wasn’t getting two-LEDs all the time, thanks to the variety of “lossless” configurations on the platform, but it was a fun game listening to the sound first and then turning over the DAC to reveal how many lights were on and if I guessed correctly. Mostly I didn’t, but perhaps that’s a testament to how clear these sound. The NHB15 is fairly neutral and less bass heavy than a typical pair of Beats, paired with the right amount of brightness on the higher frequencies.

For something with its own DAC/amplifier, the max volume isn’t as loud as I’d expect, but it’s plenty. Even when listening to Spotify, which offers no lossless music at all right now, these IEMs imbue a sense of space you’re unlikely to find with Bluetooth buds.

What’s harder to determine is whether these are OK IEMs with a nice DAC, an OK DAC with decent drivers attached or something in between. Handily, Questyle includes a regular 3.5mm cable in the box so you can use the NHB15s with all your devices or make the direct comparison yourself. At least for my ears, the Spotify tracks all sounded just as good over the trusty 3.5mm connection connected to my PC. And as far as I can tell, you can use the NHB15’s DAC cable with any IEMs you might already own as long as they have the 2-pin style connector so it’s a flexible idea if nothing else.

It’s worth mentioning that there are several competing efforts to bring wireless headphones up to par with lossless cabled options. Qualcomm’s family of codecs is the best known, with the latest AptX Lossless having the technical power to do a pretty good job even if there aren’t a lot of phones or earbuds (and you need both) that support it.

Then there’s the first wave of MEMS-based headphones, the newish kid on the block. These “solid state” drivers aren’t designed specifically for wireless headphones but California-based xMEMS is selling its technology on the promise it delivers a HiFi experience regardless of boring things like codecs. The first products to market show some promise, but we’ll likely have to wait until next year until we see MEMS-based headphones reach their full potential.

The question remains, then, who might want these? The average person paying for a regular music service doesn’t need a hi-res DAC.The average audiophile might be interested, but then it’s competing with dedicated mobile DACs and BYO headphones and for this crowd, convenience isn’t as much of a selling point. The only conclusion is that they are meant for me, the lazy audiophile. I don’t mind cables if the trade off is better, louder sound, and that’s what these do.

I’ve come to expect certain things from Audio-Technica earbuds and headphones. First, there’s the company’s warm, soothing sound profile that’s easy to listen to for hours at a time. It’s usually good, but not necessarily great, though the company typically combines it with a solid overall experience thanks to features and performance. That all holds true on the ATH-TWX7: a $199 set of wireless earbuds with active noise cancellation (ANC) and a host of handy tools that rival more expensive competitors. Some work better than others, but the company has done well over the years to expand its capabilities, even though the ATH-TWX7 lacks one basic item.

Design

Despite their stickbud appearance, the ATH-TWX7 looks more refined than most similarly-priced earbuds. Audio-Technica opted for a mix of black and silver (or white/silver or gray/silver) that makes the earbuds look similar to high-end headphones. The main housing is quite small, which translated to a more comfortable fit in my ears. The case also has a unique teardrop shape that allows the earbuds to sit at an angle rather than standing up or laying completely flat while charging. There’s no real benefit here, but it is a departure from the norm worth pointing out.

Audio-Technica did something for the onboard controls on the ATH-TWX7 that’s rare in earbuds. It uses both touch and physical buttons for playback, calls, sound modes and to summon a voice assistant. Typically you see this on headphones where the playback controls are touch and the noise cancellation and transparency modes are assigned to a button, but I don’t recall seeing both on earbuds like this before. Granted, I’ve been reviewing audio gear for several years at this point, so I hesitate to proclaim Audio-Technica as the “first” to do so.

To help you find the ideal fit, Audio-Technica includes two different types of ear tips. One is labeled “soft,” and it’s designed to be more comfortable, while the standard option is meant to offer a more secure fit. I expected the “soft” version to be foam, or at least partially foam, but they’re almost identical. One is slightly thinner, but they both seem to be the same silicone material you see in most earbuds, and neither really feels softer than the other.

The last thing I’ll point out in terms of the ATH-TWX7’s design is its ingress protection (IP) rating. These are only rated IPX4 against water splashes and they’re not built to withstand spray jets or submersion. That’s probably enough for workouts, and while it’s about average for mid-range earbuds, slightly more expensive models venture into IPX7 territory.

Software and features

When I reviewed the ATH-CKS5TW earbuds in late 2019, Audio-Technica’s app was so limited there was really no reason to ever fire it up. Unless it was to install a firmware update, it didn’t offer anything useful and even the onboard control customization was restricted. I’m happy to report that’s no longer the case as the A-T Connect software now offers a much more robust list of settings and reconfigurable tools than before.

The app's home screen is devoted to options for changing the music codec, EQ and sound mode, as well as showing the battery life for each earbud. Tapping the image of the ATH-TWX7 takes you into the detailed settings, divided into Audio and System sections. All of this is standard fare with access to everything the onboard controls offer in the app, including the ability to remap the touch and physical buttons as you wish. But despite letting you set an automatic power off timer when there’s no audio, the ATH-TWX7 doesn’t have automatic pausing when you take them out of your ears. That’s a big omission in 2024 when almost every set of wireless earbuds does this.

I will point out a couple of things that are pretty novel. First, under the Call Microphone settings, Audio-Technica goes a step further with an in-app call test so you can hear what you’ll sound like before you dial. This is in addition to features like Natural Mode for quiet locations or Noise-Reduction Mode for windy or loud environments. The latter isn’t very original, but will still come in handy. You can disable the touch controls and just rely on the tiny physical buttons on the earbuds. What is a bit innovative is the ability to tweak the sensitivity of those panels, set to medium by default with low and high options if you need ‘em.

The inclusion of both touch and physical buttons gives you a lot of flexibility in terms of how you set those up. Everything on the ATH-TWX7 is reconfigurable, which means you can move things from the buttons to the touch panels and vice versa, or add things that aren’t there by default. In addition to options for playback, calls, voice assistant and noise cancellation settings, you can add Talk-Through, Low Latency Mode and Check Battery Level. Audio-Technica didn’t reinvent the wheel in terms of what these earbuds can do, but the greater customization gives you way more options for assigning tasks in a way that makes the most sense for you.

Sound quality and noise cancellation

Photo by Billy Steele/Engadget

Nearly every set of Audio-Technica earbuds and headphones I’ve ever tested has a similar sound profile. It’s a warm, inviting tone that’s pleasant to listen to for hours on end, mostly because the dynamics aren’t exhausting. The ATH-TWX7 is more of the same, for better or worse, with some exceptions.

Softer, acoustic-driven styles are excellent, with crisp details in drums and guitars that lend texture to tracks like Zach Bryan’s “Heavy Eyes” and Charles Wesley Godwin’s “Family Ties.” The ATH-TWX7 also does well with jazz and synth-heavy pop, rock and instrumental tunes. Hip-hop is nice as well, but the earbuds start to struggle with hard rock, metal and more chaotic, bombastic genres. Better Lovers’ “30 Under 13” is still the gritty, raucous hardcore I know and love, but everything sounds flat and has less energy than on other earbuds. The sound on this album and other metal selections like Gojira’s Fortitude is more compressed than with other genres, with less space for everything to open up – especially guitars that typically soar around in your head.

Like a lot of ANC earbuds, the active noise cancellation on the ATH-TWX7 does well with constant noise, but struggles with things like human voices. This model had no trouble combatting the roar of the noisy heating unit in my Las Vegas hotel during CES, and the same goes for white noise machines and fans at home. It’s not Bose-level sound blocking, but it’s definitely above average.

Sound quality in Hear-Through or transparency mode is also quite good. There’s a nice, natural element to it that doesn’t seem as compressed or muted as some of the competition. However, the ATH-TWX7 doesn’t pipe in your voice like the AirPods Pro, so the overall effect isn’t as if you aren’t wearing earbuds at all. I assumed the Talk-Through feature would assist with this, but instead that tool simply lowers the volume or mutes content. Confusingly, despite offering two options to let in your surrounding sound, this tool doesn’t let you simply pause. It’s Hear-Through adjacent rather than a truly helpful setting for a quick chat. Because your voice isn’t beamed back to your ears, you’ll still feel the need to speak up, which means you’re more likely to get shouty if you aren’t careful.

Call quality

Props to Audio-Technica for the easiest way to check call performance ever on the ATH-TWX7. Thanks to that in-app call test, you can get an idea of how you’ll sound before answering or dialing in, which is way better than hoping you sound okay to your caller. I also found this helpful in assessing which setting worked best for where I was at the time, even if I was at home.

Noise-Reduction Mode lives up to its name, but it also sacrifices some voice quality. Natural mode sounds the best, but it picks up background noise easily. If you’re in a quiet spot though, the ATH-TWX7 gives you above-average voice performance that’s noticeably clearer than the typical speakerphone-like quality most earbuds offer.

The ATH-TWX7 also seems to struggle a bit with automatic switching via multipoint Bluetooth, but only when it comes to calls. If I was hopping from my phone to my laptop for music or some other audio, the changeover was quick and seamless. However, if I was listening to something on my MacBook Pro and got a call, there were a few times the earbuds had trouble swapping over to it. Since this is the most likely scenario in which I’d need that auto switching, this was disappointing. Best case scenario was for me to tap to change the audio from my iPhone to the ATH-TWX7 after answering, but that’s not really an ideal workflow.

Battery life

Audio-Technica promised up to 6.5 hours on the earbuds themselves with two additional charges in the case. It doesn’t specify if that’s with ANC on or off, but during my tests I had no trouble hitting the stated figure while blocking background noise. That’s doing a mix of music and calls, with the occasional few minutes of Hear-Through mode and leaving the ATH-TWX7 to automatically turn off twice. I could reliably eke out 30 minutes more than the company claimed, and a few minutes extra is always a good thing.

The competition

In the $200 price range, an apt comparison for the ATH-TWX7 are Sony’s LinkBuds S. An honorable mention on our best wireless earbuds list, these have similar battery life and the same IPX4 rating, but are more comfortable to wear and have some trademark Sony features. Those include support for DSEE Extreme upscaling in addition to Quick Attention Mode that’s handy for quick chats in the office, coffee shop or airport. What’s more, the LinkBuds S can automatically pause when you speak and an adaptive sound mode can be configured to change settings based on activity or location. Plus, they’re available for $200 at full price.

iPhone owners will be more satisfied with the second-gen AirPods Pro over the ATH-TWX7. Currently available for under $200, the 2022 version of the earbuds are the best option if your life is intertwined with iOS, iPadOS and macOS. New features like Adaptive Audio bring automatic adjustments to your day and Apple’s take on transparency mode continues to be the best in the business. Lastly, they’re more comfortable for a longer period of time than the ATH-TWX7.

Wrap-up

There’s plenty to like about the ATH-TWX7. A robust set of features brings a lot of convenience to your day. But a few of those tools could still use some fine-tuning and the lack of automatic pausing in 2024 is a head scratcher. Still, the audio is mostly good, albeit inconsistent at times, and transparency mode is better than most. Add in the solid call quality and the in-app voice test and the ATH-TWX7 are a worthy consideration, especially at this price. Too bad it falls short of being a more complete package some of the competition offers for a slightly larger investment.

At CES 2023, Roland introduced a streaming mixer called Bridge Cast, which can give creators a way to pipe different audio feeds to different destinations and make it easy for them to create mixes, add vocal effects and remove unwanted audio. Now, the company has unveiled a follow-up to the device called Bridge Cast X that adds video support on top of all its predecessor's audio-focused features. The Bridge Cast X has two HDMI input ports and an HDMI Thru connector that can feed video up to 4K in resolution to an external monitor. 

As for audio, creators can plug in broadcast-quality XLR mic and headphones if they use those accessories. They can also adjust sounds to ensure that they can clearly hear the game's audio and voice chat more clearly than any background sounds. Meanwhile, they can broadcast a different mix that's optimized for maximum viewer engagement. The device has dedicated volume knobs for different input sources and audio output, and it has programmable buttons creators can use to mute specific sounds and to do various functions. 

On the software side of things, the BGM Cast service on Roland Cloud will give creators access to thousands of royalty-free music tracks that they can use as sound effects and background audio. They will need to sign up for a Roland Cloud Core membership that costs $3 a month or $30 a year to be able to use all those tracks, but a free account still gives them free access to 36 background music tracks and 16 sound effects. The Roland Bridge Cast X will start shipping in the US in February and will cost buyers $500.

Well, this is certainly an interesting way to debut a new set of wireless earbuds. Bose announced today that it has teamed up with fashion and lifestyle brand Kith to release its newest product: the Ultra Open Earbuds. The news follows a leak during CES that tipped the rather unique design, a set of buds that clip onto your ears and leave the ear canal open to let outside noise in. Details are scarce in terms of key specs, but here's what the company did reveal in the announcement. 

Bose describes the Ultra Open Earbuds as "an innovative cuff-shaped design with polished, soft edges and a stunning finish." In a departure from its previous "open" model, these earbuds attach to the side of your ears instead of being secured with an over-the-ear hook. Bose says this makes the buds more of a fashion accessory than an "audio wearable," which explains the collab. The company also says you can wear them with a hat, glasses or jewelry with no issues, since they sit further down your ear. It's also touting increased comfort and "all-day wear," since you don't have to choose between tuning into your surroundings or listening to audio content. 

Bose

Detailed specs are scant for now, but Kith spilled a few items on its website. The fashion company further describes the design as having "a light-as-air grip" and "a flexible joint" for getting them on and off with ease. You can expect up to seven and a half hours of playtime with Bose Immersive Audio for spatial sound and "an additional suite of state-of-the-art technologies." The iconic Bose branding has been replaced with a Kith logo in the same lettering style on both the earbuds and the charging case. Bose says this marks its first partnership with a fashion brand, and it's noteworthy that the company is letting a collab reveal an all-new product rather than a limited-edition version of an existing one. 

The Bose Ultra Open Earbuds will be available for $300 on January 22 on Kith.com and in select Kith stores "in extremely limited quantities." I'm guessing the company will debut a proper version with its own branding soon enough, but there's no mention of that in today's announcement. 

Audio cues can sometimes be crucial for success in games. Developers frequently design the sound environment for their experiences to be not only rich and immersive, but to also contain hints about approaching enemies or danger. Players who are hard of hearing can miss out on this, and it's not fair for them to be disadvantaged due to a disability. A product called Audio Radar launched at CES 2024 and it can help turn sound signals into visual cues, so that gamers with hearing loss can "see the sound," according to the company AirDrop Gaming LLC. 

The setup is fairly simple. A box plugs into a gaming console to interpret audio output and converts that data into lights. A series of RGB light bars surround the screen, and display different colors depending on the type of sound coming from the respective direction they represent. Put simply, it means that if you're walking around a Minecraft world, like I did at the company's booth on the show floor, you'll see lights of different colors appear on the different bars.

Red lights mean sounds from enemies are in the area adjacent to the corresponding light, while green is for neutral sounds. An onscreen legend also explains what the sounds mean, though that might just be for the modded Minecraft scenario on display at CES.

I walked around the scene briefly, and could see green lights hovering above a pen of farm animals, while purple lights fluttered in tandem with a dragon flying overhead. I did find it a little confusing, but that is probably due more to the fact that I know very little about Minecraft, and as someone with hearing I might not appreciate the added information as much as someone without.

With an SDK that the company launched at the show, developers will be able to customize the lights and visual feedback to elements in their game so that they have control over what their hard-of-hearing gamers see. In the meantime, Audio Radar is using its own software to detect stereo or surround sound signals to convert to feedback in lights and colors. 

Though the product may seem in its early stages, various major gaming companies have appeared to indicate interest in Audio Radar. AirDrop Gaming's CEO Tim Murphy told me that Logitech is "providing support as we further develop our product and design our go-to-market strategy." Also, Microsoft CEO Satya Nadella was spotted at the booth on opening day.

Audio Radar is beginning to ship on a wider level this year, and the company continues to develop products for gamers who are deaf and hard of hearing, among other things. The system works with Xbox, PlayStation and PC.

We're reporting live from CES 2024 in Las Vegas from January 6-12. Keep up with all the latest news from the show here.

So much of what we see at CES tends to be focused on technological innovation for the sake of innovation, or obvious attempts to tap into whatever trend is gripping the internet's attention that year. In the last few shows, though, there has been a heartening increase in attention to assistive products that are designed to help improve the lives of people with disabilities and other different needs. At CES 2024, I was glad to see more development in the accessibility category, with many offerings appearing to be more thoughtfully designed in addition to being clever. It's so easy to get distracted by the shiny, eye-catching, glamorous and weird tech at CES, but I wanted to take the time to give due attention to some of my favorite accessibility products here in Las Vegas.

GyroGlove

Before I even packed my bags, numerous coworkers had sent me the link to GyroGlove's website after it had been recognized as an honoree for several CES Innovation awards. The device is a hand-stabilizing glove that uses gyroscopic force to help those with hand tremors minimize the shakes. Because the demo unit at the show floor was too large for me, and, more importantly, I don't have hand tremors, I couldn't accurately assess the glove's effectiveness. 

But I spoke with a person with Parkinson's Disease at the booth, who had been wearing one for a few days. She said the GyroGlove helped her perform tasks like buttoning up a shirt more easily, and that she intended to buy one for herself. At $5,899, the device is quite expensive, which is the sad state of assistive products these days. But GyroGlove's makers said they're in talks with some insurance providers in the US, which could lead to it being covered for those in America who could benefit from it. That's one of the biggest reasons that led us to name GyroGlove one of our winners for CES 2024.

MouthPad

I did not think I'd be looking deep into a person's mouth and up their nose at CES 2024, but here we are. Sometimes you have to do strange things to check out unconventional gadgets. The MouthPad is as unusual as it gets. It's a tongue-operated controller for phones, tablets and laptops, and basically anything that will accept a Bluetooth mouse input. The components include a touchpad mounted onto the palette of what's essentially a retainer, as well as a battery and Bluetooth radio. 

As odd as the concept sounds, it actually could be a boon for people who aren't able to use their limbs, since your tongue, as a muscle, can offer more precise movement and control than, say, your eyes. If you're feeling apprehensive about sticking a device inside your mouth, it might be helpful to know that the battery is from the same company that's made them for medical-grade implants, while the rest of the dental tray is made from a resin that's commonly used in aligners and bite guards. The product is currently available as an early access package that includes setup and calibration assistance, with a new version (with longer battery life) slated for launch later this year.

Assistive tech company OrCam won our Best of CES award for accessibility in 2022, so I was eager to check out what it had in store this year. I wasn't disappointed. The company had a few updated products to show off, but the most intriguing was a new offering for people with hearing loss. The OrCam Hear system is a three-part package consisting of a pair of earbuds, a dongle for your phone and an app. Together, the different parts work to filter out background noise while identifying and isolating specific speakers in a multi-party conversation.

At a demo during a noisy event at CES 2024, I watched and listened as the voices of selected people around me became clear or muffled as company reps dragged their icons in or out of my field of hearing. I was especially impressed when the system was able to identify my editor next to me and let me choose to focus on or filter out his voice. 

Audio Radar

If you're a gamer, you'll know how important audio cues can sometimes be for a successful run. Developers frequently design the sound environment for their games to be not only rich and immersive, but to also contain hints about approaching enemies or danger. Players who are hard of hearing can miss out on this, and it's not fair for them to be disadvantaged due to a disability. 

A product called Audio Radar can help turn sound signals into visual cues, so that gamers with hearing loss can "see the sound," according to the company. The setup is fairly simple. A box plugs into a gaming console to interpret the audio output and convert it into lights. A series of RGB light bars surround the screen, and display different colors depending on the type of sound coming from the respective direction they represent.

CES 2024 saw not just Audio Radar's official launch, but was also where the company introduced its SDK for game developers to create custom visual cues for players who are hard of hearing. The company's founder and CEO Tim Murphy told Engadget that it's partnering with Logitech, with the gaming accessory maker "providing support as we further develop our product and design our go-to-market strategy."

Transcribe Glass

Google Glass was resurrected at CES 2024. Sort of. A new product called Transcribe Glass is a small heads up display you can attach to any frames, and the result looks a lot like the long-dead Google device. It connects to your phone and uses that device's onboard processing to transcribe what it hears, then projects the text onto the tiny transparent display hovering above the eye. You'll be able to resize the font, adjust the scrolling speed and choose your language model of choice, since TranscribeGlass uses third-party APIs for translation. Yes, it converts foreign languages into one you understand, too. 

The company is targeting year's end for launch, and hoping to offer the device at $199 to start. When I tried it on at the show floor, I was surprised by how light and adjustable the hardware was. I had to squint slightly to see the captions, and was encountering some Bluetooth lag, but otherwise the transcriptions took place fairly quickly and appeared to be accurate. The TranscribeGlass should last about eight hours on a charge, which seems reasonable given all that it's doing. 

Samsung's subtitle accessibility features

Though we didn't catch a demo of this in person, Samsung did briefly mention a "sign language feature in Samsung Neo QLED" that "can be easily controlled with gestures for the hearing impaired, and an Audio Subtitle feature [that] turns text subtitles into spoken words in real-time for those with low vision." We weren't able to find this at the show, but the concept is certainly meaningful. Plus, the fact that Samsung TVs have mainstream appeal means these features could be more widely available that most of the niche products we've covered in this roundup.

One of the key advantages of Bluetooth LE Audio is Auracast: a way to broadcast content to connected devices in public settings. It will also allow you to easily connect multiple wireless speakers to each other with diving into an app. Perhaps most importantly, the barrier to entry is going to be very low since a dedicated Auracast app will be built into mobile platforms like iOS and Android. What's more, you'll select available channels like you would a Bluetooth device or a Wi-Fi network. It's simple, and it's presented in a way that people who've used a smartphone are familiar with. Auracast has been mentioned constantly by companies announcing their new audio gear at CES 2024, so here's what you need to know about it. 

What is Auracast?

Simply put, Auracast is broadcast audio over Bluetooth. An Auracast transmitter, which in public settings can be a pro-grade add-on to a TV or a box that looks like a Wi-Fi router mounted on the wall. You can also create your own channels from a phone or laptop to share music of the sound from a TV show. This means that you'll be able to have the audio from muted airport TVs beamed to your headphones or earbuds when traveling. Auracast will also allow you to keep tabs on flight and gate information without interrupting your layover entertainment. 

During its CES demo, Bluetooth SIG, the organization that defines Bluetooth standards, allowed show-goers to experience the aforementioned airport TV scenario. It was easy to switch between two sports broadcasts in a faux bar, simply by tapping one or the other in the Auracast menu. Another tap let us hear a private stream from a laptop, which was password protected so only the proper invitees can access it. There's also a use case where live audio from a lecture or performance can be broadcast via Auracast directly to earbuds, hearing aids or other Bluetooth listening devices. Impressively, there's no lag across any of the options as the visuals matched up perfectly each time.

"The analogy I would use is very similar to setting up a personal hotspot," Chuck Saban, senior director for market development at the Bluetooth, explained about those private Auracasts. "You would set up a personal audio hotspot, it's going to be encrypted, and then anybody who is around me who has that passcode can listen."

Auracast will also help you link multiple Bluetooth speakers together at the press of a button. Until now, most companies had you select the devices in an app. But companies like JBL are putting dedicated Auracast buttons on some of their new devices. On the company's PartyBox line, for example, you'll press the button on the main speaker you connected to your phone and then all you have to do is press the button on successive units to link them. What's more, you can chain together an infinite number of speakers in this scenario. 

What devices is Auracast available on?

Auracast is a feature of Bluetooth LE Audio that arrived with Bluetooth 5.2. So technically, any earbuds, headphones, hearing aids, speakers and other devices that have that version of the wireless standard will be able to tune into Auracast. However, Bluetooth 5.3 offers a more robust implementation of the broadcast audio tool. 

"What you get with 5.3 is the ISOC channels capability in the core that allows multiple independent channel capabilities," Saban said. "You effectively can parse out the left and right [channels] from the source itself." He further explained that the processing of all of that has been moved to the phone from the earbuds or headphones themselves, which extends battery life, performance and efficiency for Bluetooth devices. 

When will Auracast be available?

Plenty of Bluetooth devices support Bluetooth 5.2 or 5.3 and LE Audio. Since Auracast is part of Bluetooth, there's no extra tech needed to include it, the products just need to support the recent versions of the wireless standard. From there, it's up to the individual companies to flip the switch on LE Audio and Auracast. Over the course of 2023 and here at CES, tons of audio brands have said they are planning to add support for the feature via over-the-air updates later in 2024.

While MEMS drivers may be the next big thing in true wireless earbuds, the first models with the solid-state components still require a hybrid setup. These products pair a MEMS speaker with a dynamic driver to ensure proper bass performance. The current-gen driver from xMEMS, a California-based company that develops the audio components, is called Cowell and it's already available in earbuds from the likes of Creative and Noble Audio. 

The next-gen MEMS driver is called Cypress, and while it won't arrive in new products until 2025, I got a chance to hear the difference been it and Cowell at CES 2024 here in Las Vegas — and it's quite striking. With Cowell, there's bass, but it's subdued and the emphasis is on the highs and the mids. It sounds great, on both complete products and reference designs, offering punchy highs, full mids and great clarity. With Cypress alone though, there's a blanket of warm, bassy low-end that really fills out the soundstage. It will be a massive improvement for what MEMS drivers are capable of doing for wireless earbuds. 

"We moved to a sound from ultrasound principle where we have ultrasonic modulation and demodulation to deliver 30 to 40 times greater low-frequency pressure for anti-noise generation for ANC earbuds, while still delivering all of the benefits of our solid state speakers," xMEMS vice president of marketing Mike Housholder explained. "Wide dynamic range, with excellent low-frequency performance for deep bass and noise cancellation."

Indeed, that 30 to 40 times louder bass response was clearly evident when on a Cypress reference design. The prototype was built to showcase the MEMS drivers on their own, without that secondary dynamic driver today's true wireless models require for bass. The results are the pristine clarity you'd expect in a send of high-end wireless headphones or even some audiophile-grade cans. The additional bass isn't loud and boomy, but instead it's warm and full, inviting you to stay and listen a while. And that I did: I had a hard time putting the Cypress prototype down even when I felt I'd overstayed my welcome. 

On the whole, MEMS drivers offer a host of benefits over coil speakers that should all lead to better audio quality in your earbuds. They're more efficient in terms of mechanical response, with faster speeds there contributing to increased detail and clarity — something I certainly noticed on the Noble Audio FoKus Triumph wireless earbuds. This model pairs Cowell with a 6.5mm dynamic driver, but the boost in fidelity in the mids and highs is apparent. And getting a set of earbuds with MEMS drivers doesn't mean you'll pay more. The two models Creative has already debuted are $130 and $150. The same will be true for upcoming products with the ultrasonic Cypress drivers, according to Housholder. 

"We see ourselves going to market first in flagship products," he said. "As with our current products, we really see the sweet spot for our products anywhere 150 and up, [which] is easily achievable day one. And then over time and over volume, getting down to that $100 price point."

And that's really the big takeaway from me. For years, companies have offered true wireless earbuds with some of the features of more premium flagship models, but usually lacking the sonic performance of pricier options. With MEMS drivers, the audio quality is greatly improved in affordable models that are half the price of the top-of-the-line Sony or Sennheiser noise-canceling earbuds. And with Cypress, xMEMS can offer audio companies the ability to improve overall sound quality without having to raise prices. 

xMEMS has also developed what it calls a DynamicVent to relieve occlusion in sleep earbuds. The component can automatically open or close depending on if the buds detect ambient noise like a snoring spouse. When open, the DynamicVent offers a semi-open fit like AirPods, but when it's closed the ear will be completely sealed off. The open vent should also keep sounds of your own breathing or the earbuds rubbing against a pillow from disturbing your sleep. xMEMS is showing off the DynamicVent at CES in a set of reference sleep buds equipped with its Cowell MEMS drivers.

Sennheiser announced two very different sets of wireless earbuds at CES 2024 here in Las Vegas, extending its Momentum line with a fourth-generation flagship model and a high-tech sport version. The company's premium earbuds have offered excellent sound quality for a while now, consistently earning the best overall audio in our best wireless earbuds list. We paid Sennheiser a quick visit to see how the two new sets stack up. 

There's no need to mince words here: The audio performance on the Momentum True Wireless 4 is outstanding. I only listened to them for a few minutes, but I had a hard time walking away. The jazz demo tracks the company selected played to the earbuds' strengths with excellent clarity and pleasant, inviting tuning. Active Noise Cancellation (ANC) also seems to be improved as I was able to silence a noisy hotel suite at the press of a button. Transparency mode is also better and more natural sounding, but you still don't get as much of your voice beamed back through the earbuds as you do on the AirPods Pro. 

Sennheiser clarified during my demo that its stated battery life on the Momentum True Wireless 4 of seven and a half hours is with ANC off. However, it explained that it has narrowed the gap in regards to noise cancellation impacting battery life as enabling it only reduces play time by 30 minutes.

I'm also happy to report there's no discernible drop off in audio quality with the Momentum Sport. There's still crisp, clear sound that's evenly tuned despite the company's goal of "impressive bass" for workouts. There's ample low-end tone here, but it didn't seem to be cranked any higher than the Momentum True Wireless 4. The size of the Sport model makes them very comfortable to wear and the ANC seemed to do a solid job blocking the roar of CES surrounding us.

The Momentum True Wireless 4 goes on sale March 1 and the Momentum Sport will be available April 9. I'll be putting both sets of earbuds through their paces closer to their respective launch dates.
