As rumors continue to swirl about Apple’s potential entry into the smart glasses market, xMEMS Labs plans to unveil innovations that could address some of the biggest challenges facing next-generation wearable devices, the company said Tuesday. At September events it will roll out new xMEMS Labs smart glasses prototypes featuring ultra-thin speakers and active cooling technology that promise to make AI-powered eyewear more comfortable and practical for everyday use.

Here’s some encouraging news for Apple users eagerly awaiting the next generation of smart wearable — new technology could cool down overheating smart glasses. The world’s first active cooling system small enough to fit inside the frame of smart glasses arrives with µCooling fan-on-a-chip technology, xMEMS Labs said Tuesday.
That potentially addresses one of the biggest obstacles facing AR glasses projects like Apple’s rumored one. A sophisticated system in a frame generates heat against a user’s skin, and a passive heat sink may not dissipate it enough.

A tiny new silicon micro-speaker could transform future wearables — like Apple Watch and other smartwatches — by dramatically reducing thickness while improving audio quality, xMEMS Labs said Tuesday. It unveiled Sycamore-W, an ultra-thin micro speaker engineered for wrist-worn devices. It could make more room in devices as new features like AI interactions become more prevalent.
“Sycamore-W redefines audio for smart watches, combining compact design with robust performance to meet the demands of next-generation wearables,” said Mike Housholder, xMEMS VP of Marketing and Business Development. “As the wrist becomes a key interface for ears-free, hands-free AI interactions, Sycamore-W empowers manufacturers to deliver premium audio in smaller, lighter more durable devices.”
A cutting-edge pair of AI sports glasses feature innovative audio technology from xMEMS Labs, the company said Tuesday. The new BleeqUp Ranger glasses, developed by Chinese startup BleeqUp, represents the first commercial use of a xMEMS solid state microtweeter in AI eyewear — but likely not the only one.
“xMEMS is proud to help power the next generation of AI wearables,” said Steven Bentley, VP of worldwide sales at xMEMS Labs. “The integration of Cowell into BleeqUp’s glasses not only showcases the high-fidelity performance of our MEMS speakers. We’re excited to help more companies accelerate their path to market with compact, high-performance audio solutions for AI glasses.”
Perhaps that, or the upcoming uses of xMEMS Labs’ Sycamore microspeaker, could signal a new direction for Apple if it revives its smart glasses project.

The new solid-state xMEMS Labs Lassen micro speaker is a silicon micro electro-mechanical systems (MEMS) tweeter. It eliminates the need for a separate piezo amplifier while delivering premium sound quality in wireless earbuds, xMEMS Labs said Thursday. As the company’s latest tiny speaker, it could play a big role in next-gen buds.
“Lassen is a revolutionary design based on a proven platform,” said Mike Housholder, VP of Marketing & Business Development at xMEMS. “It will bring the benefits of 2-way earbud audio to a broader market by eliminating the extra cost of the piezo amplifier and minimizing the space and power required to deliver a truly immersive TWS sound experience.”

After testing Creative Aurvana Ace 2 earbuds, I’ve found them to be a fascinating glimpse into the future of portable audio technology — albeit with some growing pains at this early stage. The $149.99 buds — often discounted — represent one of the first consumer implementations of xMEMS solid-state driver technology. But the impressive audio quality doesn’t make these earbuds as great as they could be because of other shortcomings.
Aurvana Ace 2 came out about a year ago, but this marks my first time experiencing xMEMS Labs micro speakers I’ve written about several times, so I was happy to try them out.

In what could be a breakthrough for wearables and other electronics, xMEMS Labs unveiled Sycamore on Tuesday. It’s the world’s first full-range near-field MEMS micro speaker. Measuring just over one millimeter thick, the innovation promises to make some noise with compact gear you don’t put in your ears. Those would be items like open-fit earbuds, such as AirPods and sport earphones, smartwatches like Apple Watch, AR glasses and headsets like Vision Pro, and other consumer electronics.
Like other xMEMS micro speakers that bring solid-state sound to earbuds and headphones, the new technology uses a novel “sound from ultrasound” platform. It generates full-frequency audio from ultrasonic waves within a chip-sized form factor.
“With Sycamore, mobile electronics can now achieve thinner, more stylish form factors while maintaining big, rich sound,” said Mike Housholder, xMEMS VP of marketing and business development. “With better performance at both the low and high ends, Sycamore delivers powerful, full-range audio for smartwatches, smart glasses, and any other small, mobile form factor that engineers dream up.”

xMEMS Labs, creators of all-silicon micro speakers for earbuds and headphones, plan to roll out the xMEMS XMC-2400 µCooling chip, the company said Tuesday. It noted the 1mm xMEMS fan on a chip is the first all-silicon, active micro-cooling fan for smartphones, tablets and other mobile devices.
“Our revolutionary µCooling ‘fan-on-a-chip’ design comes at a critical time in mobile computing,” said Joseph Jiang, xMEMS CEO and co-founder. “Thermal management in ultra-mobile devices, which are beginning to run even more processor-intensive AI applications, is a massive challenge for manufacturers and consumers. Until XMC-2400, there’s been no active-cooling solution because the devices are so small and thin.”
The company declined to comment on whether it’s in talks with Apple as a client or partner with the new innovation. See our Q&A with xMEMS Labs below.

The first over-ear headphones with solid-state micro speakers are almost here, AMPACS said Tuesday. It noted reference-design prototypes with xMEMS solid-state micro speakers are now available. That brings us one big step closer to headphone makers putting it in their new headphones. That could start after the production version of the design becomes available to them in September. Before now, the new micro speakers were limited to earbuds.
xMEMS Labs’ patented 2-way module architecture uses solid-state micro speakers for mids and highs and a dynamic driver for bass. It improves spatial audio accuracy and reduces weight for gamers compared to conventional single-driver cans, AMPACS said. The new reference design is a cost-effective advance that could figure into multiple audio brands’ headphones.
Ahead of the latest news, Cult of Mac conducted an interview with folks behind the development from xMEMS Labs in May. After all, you have to wonder if some future AirPods Max or Beats cans might incorporate the technology (for the record, xMEMS told Cult of Mac it’s open to working with all partners, but confirmed none).

Audio brands and manufacturers can now buy cutting-edge reference designs for solid-state, all-silicon micro speakers online to bring new generations of true wireless stereo (TWS) earbuds and in-ear monitors (IEMs) to market faster, xMEMS Labs said Tuesday.
This is another step toward realizing the “ultrasonic revolution” I wrote about in-depth in November 2023. In it, old-school speaker technology still used even in tiny earbuds may give way to new solid-state tech providing the full sonic range digitally compressed audio has compromised.
“Steve Jobs was a digital pioneer, but when he went home, he listened to vinyl,” classic rocker and noted audiophile Neil Young once said. He was getting at all the sonic detail lost to digital compression in forms like MP3 files.
