xMEMS is a company that so far is best known for its MEMS—or microelectromechanical systems—based speaker drivers, but since around the middle of last year, the company has also developed a range of MEMS based cooling solutions. The xMEMS µCooling is competing with a range of new cooling solutions from several new companies and, although their current solution is unlikely to find its way into laptops today, the company has tested to cool hotter running chips using multiple MEMS µCooling modules to great success. The XMC-2400—also known as Sequoia—is the first product and it has an airflow of up to 35 cubic centimeters per second, which isn't a huge amount, but the cooler is said to be inaudible during operation and it also has the added benefit of being waterproof and the entire MEMS cooling module can be soldered in place. At an estimated power consumption of a mere 30 mW, it's also a very power efficient cooling solution. xMEMS had some demos at its booth, of which the one pictured below shows the XMC-2400 blowing or sucking air, with a small fan-wheel spinning to show the movement of the air. Another showcased the static pressure, pushing air through tubing and into a beaker filled with water. Potential applications include removing hot air from phones, although we may see some smaller SoCs getting cooled too.

Creative has expanded its Aurvana Ace family of xMEMS driver-equipped true wireless earbuds—two new models are on show at this year's CES trade event. The Aurvana Ace SXFI and Aurvana Ace Mimi were revealed prior to CES 2025's commencement, with reviewers in Singapore (where Creative is headquartered) already picking up samples for evaluation. The latest additions also house solid-state xMEMS drivers that works in conjunction with 10 mm dynamic diaphragm units. The TechPowerUp team took a look at the demonstration units on hand at Creative's station—a sense of familiarity was apparent with one of these models.

The collaboration between Creative and Mimi Hearing Technologies has produced the aptly named "Aurvana Ace Mimi"—from the outside this looks like a slight recoloring of the 2023 Ace and Ace 2 models. The Mimi's pricing is apparently somewhere in between the older iterations. A major change addition lies under the hood, due to the implementation of Mimi's Sound Personalization technology. A user can perform a hearing test via the Creative App. It is claimed that this analysis will produce a custom sound profile/EQ—tuned specifically for "every individual."

xMEMS Labs, developers of the foremost platform for piezoMEMS innovation and creators of the world's leading all-silicon micro speakers, today announced collaboration with SOUNDPEATS to equip its all-new Capsule3 Pro+ TWS earbuds with its Cowell micro speaker. Cowell is the world's smallest full-range, all-silicon, solid-state speaker that delivers precise, high-fidelity, high-resolution audio, phase consistency, and high-frequency extension.
Capsule3 Pro+ are the first product from SOUNDPEATS to leverage xMEMS' solid-state micro speakers, and, as a result, excel in sound quality and elevate the user listening experience.

The Capsule3 Pro+ TWS earbuds use xMEMS' Cowell as the tweeter for exceptional high-frequency response and a 12 mm dynamic driver for mid-bass production. With the dual speakers working in tandem, the earbuds deliver well-balanced sound with both powerful bass and pristine high-frequency details - that overcome the typical sound quality limitations of TWS earbuds. Consumers can also expect a more comfortable and ergonomic fit with the Capsule3 Pro+ TWS earbuds due to the integration of xMEMS' compact hardware.

xMEMS Labs, developers of the foremost platform for piezoMEMS innovation and creators of the world's leading all-silicon micro speakers, today announced its latest industry-changing innovation: the xMEMS XMC-2400 µCooling chip, the first-ever all-silicon, active micro-cooling fan for ultramobile devices and next-generation artificial intelligence (AI) solutions.

For the first time, with active, fan-based micro-cooling (µCooling) at the chip level, manufacturers can integrate active cooling into smartphones, tablets, and other advanced mobile devices with the silent, vibration-free, solid-state xMEMS XMC-2400 µCooling chip, which measures just 1-millimeter thin.

Furthering the integration of solid-state micro speakers in over-the-ear headphones, AMPACS, a global leader in electroacoustic product design, today announced a turnkey 2-way headphone solution designed in collaboration with MEMS audio and semiconductor pioneer xMEMS Labs. Pre-production prototypes are ready now, and the production-ready solution will be available in September.

The design leverages xMEMS' Cowell, the world's smallest solid-state micro speaker, for precisely rendered highs and mids, and AMPACS' dynamic driver providing deep, satisfying bass. The result is a ready-made, modular solution that headphone manufacturers can plug into virtually any headphone design, including open-back, closed-back, wired, and wireless, for next-level gaming and music listening experiences.

Accelerating the adoption of solid-state micro speakers in consumer audio products, MEMS audio and semiconductor pioneer xMEMS Labs today announced the availability of two innovative reference designs for purchase at the xMEMS web store.

The first unit, known as Harding, serves as xMEMS' reference design for 2-way True Wireless Stereo (TWS) earbuds, while the other is for audiophile-level full-range in-ear-monitors (IEMs). Both are available for a limited time and in extremely limited quantities, with the goal of providing interested audio brands and manufacturers with accelerated time-to-market leveraging xMEMS' patented designs.

Noble Audio today launched the FoKus Triumph TWS (True Wireless Stereo) earbuds, showcasing the company's renowned sound quality in a TWS package. FoKus Triumph is driven by a custom 6.5 mm dynamic driver coupled with Cowell, an all-silicon MEMS-based speaker from xMEMS Labs, pioneers in "Solid-State Fidelity."
FoKus Triumph is Noble's third product, following the Falcon Max and XM1, to benefit from a strategic partnership with xMEMS. Leveraging xMEMS Cowell to deliver exceptional sound quality, phase coherence, and treble extension, FoKus Triumph is the latest evidence of Noble Audio's status as a pioneer in premium portable audio.

Noble Audio's latest fully wireless earbuds incorporate a custom dynamic driver for accurate bass and midrange reproduction with xMEMS' Cowell solid state driver serving as a tweeter. Pre-production units with this hybrid design were tested by hundreds of visitors at xMEMS' CES suite in January, and they received high marks for sound quality.

xMEMS Labs, pioneers in solid-state, all-silicon micro speakers, today announced a revolutionary breakthrough in sound reproduction, changing the way mass-market, true wireless stereo (TWS) earbuds create ultra high-quality, high-resolution sound experiences across all audio frequencies.

With the introduction of its groundbreaking new Cypress solid-state MEMS speaker, xMEMS engineers have replaced legacy push-air sound reproduction with the company's ultrasonic amplitude modulation transduction principle. Ultrasonic modulation turns ultrasonic air pulses into rich, detailed, bass-heavy, high-fidelity sound, representing the first no-compromise alternative to the moving-coil concept for high-volume consumer active noise canceling (ANC) earbud micro speakers.

Creative Technology today announced the release of the much-anticipated Creative Aurvana Ace and Creative Aurvana Ace 2, the latest true wireless earbuds featuring the groundbreaking solid-state, all-silicon MEMS-based drivers. The Creative Aurvana Ace series, powered by xMEMS drivers, has been expertly tuned to deliver remarkable audio clarity with a wider frequency response ranging from 5 Hz to 40 KHz. With this comprehensive range, users will get to enjoy a truly immersive and lifelike audio experience, whether it's for music, movies, or conference calls.

These latest wireless earbuds also feature LE Audio with LC3 codec, Bluetooth 5.3, and Hybrid Active Noise Cancellation (ANC) plus Ambient Mode, along with up to 24 hours of total playtime, making them the definitive choice for audio enthusiasts seeking the very best in true wireless earbuds.
