xMEMS Labs, developers of the foremost platform for piezo MEMS 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 12mm 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.

According to VP Marketing and Business Development at xMEMS Mike Housholder, “Cowell is a leap forward in audio fidelity, setting a new standard for high-resolution, lossless audio in TWS earbuds. We’re excited to bring the Cowell micro speaker to SOUNDPEATS specifically and the TWS market more broadly – helping manufacturers develop high-quality audio products at scale and stand out in an increasingly competitive market.”

The quality of Cowell’s mid-to-high range sound and enhanced high-frequency detail immerses consumers in a broader soundstage where every detail comes to life with unparalleled clarity and precision.

Measuring 3.2 x 6.0 x 1.15mm and weighing only 56 milligrams, Cowell is the first speaker to use xMEMS’ second-generation M2 unit architecture, offering increased volume in a smaller form factor. Available in both top-firing and side-firing packages, Cowell also provides additional sound pressure above 1kHz, significantly improving the speech signal-to-noise ratio of voices and enhancing the clarity of vocals and instruments.

The Capsule3 Pro+ earbuds support LDAC, a high-efficiency audio codec that enables high-resolution audio with a maximum sampling rate of 96kHz and 24-bit depth when paired with a compatible device. Certified as Hi-Res Audio Wireless, these earbuds meet the Japan Audio Society’s standards for high-frequency reproduction and signal processing.

Along with high-quality audio, the new Capsule3 Pro+ earbuds also offer AI adaptive environmental noise cancellation, which detects and reduces noise based on external conditions and the wearing state, providing an immersive and interference-free noise cancellation experience.

The six built-in microphones accurately capture noise during calls, providing a high-definition and quiet environment. Features such as wind noise reduction, 43 hours of battery life, dual-device connectivity, and low-latency gaming mode further enhance the consumer experience.

Recently, xMEMS has also announced several reference designs leveraging Cowell, including the industry’s first 2-way over-ear headphone reference design, as well as cutting-edge reference designs for TWS earbuds and in-ear-monitors.

The SOUNDPEATS Capsule3 Pro+ TWS earbuds are available for purchase here for less than $100.
