Behind the Scenes, SonicEdge Expands Sampling Program for Its Patented SonicTwin Module. Is This the Future of Wearables?

(October 23, 2025) Every once in a while, I pick up a story from deep within the manufacturing world that peels back the curtain on how the audio products we use every day are actually made. Today’s announcement from SonicEdge, an Israeli micro-acoustic specialist, does just that, offering a glimpse into a technology that could reshape how wearable devices produce sound.

The company has expanded a sampling program for its SonicTwin (ST100M), a next-generation module that combines a speaker and microphone into a single 8 x 4 x 1 millimeter housing. It's a small piece of hardware with significant implications, balancing miniaturization and performance in ways that could simplify product design and improve the sound quality of tomorrow’s wearables.

At the core of the ST100M is what SonicEdge calls audio from ultrasound technology, a patented approach that replaces traditional voice coils with modulated ultrasound to generate audible sound. Because it doesn't rely on mechanical vibration, the system eliminates resonance and interference between the speaker and microphone, allowing both to work together in perfect synchronization. That development helps reduce distortion, improve clarity, and maintain audio consistency in tight spaces where conventional components typically won't fit.

The company’s MEMS-based design, using microelectromechanical systems similar to those found in sensors and microchips, achieves a tenfold reduction in size compared to discrete components while maintaining high Sound Pressure Levels across a 5 Hz to 50 kHz frequency range. The result is full-spectrum sound reproduction, apparently including ultra-deep bass, from components that are nearly invisible to the eye.

Because the speaker and sensor are co-located, latency within the active noise cancellation loop is dramatically reduced. This results in faster and more stable ANC performance that maintains accuracy across the full frequency range. By eliminating structural noise and vibration, SonicTwin also creates a more reliable baseline for voice capture and environmental awareness, both of which are essential for next-generation True Wireless Stereo and AR or VR applications.

There are practical benefits too. The spatial efficiency of the ST100M should allow for smaller and lighter designs, giving engineers more room for larger batteries or additional sensors. The simplified construction also lays the groundwork for fewer parts, thereby reducing manufacturing complexity and cost. For consumers, that could translate to earbuds with longer battery life, better comfort, and more consistent sound from one ear to the other.

While SonicEdge is not a consumer brand, its technology could soon appear in products that define the next wave of wearable innovation. SonicEdge CEO Moti Margalit describes the SonicTwin as “a complete digital acoustic module that doesn’t just improve audio, it redefines what is possible in the design of miniature sound systems.” The company has already partnered with select manufacturers for early testing and is now expanding its ST100M sampling program to include additional qualified partners. The program provides participants with access to engineering samples, integration support, and deployment assistance from SonicEdge’s engineering team.

For a company that typically operates behind the scenes, SonicEdge’s innovation represents an important step toward the next generation of ultra-compact, high-performance sound. As more manufacturers test and integrate SonicTwin technology, consumers may soon experience its impact in clearer calls, longer playtime, and smaller, more comfortable devices.
