The V2S by Knowles is a high-bandwidth, low-power digital voice vibration sensor designed to improve voice call quality in noisy environments. It selectively captures the speaker’s voice while suppressing background noise like wind and crowds. Ideal for devices like True Wireless Stereo (TWS) earbuds, its compact size and Pulse Density Modulation (PDM) interface allow for easy integration without compromising design or battery life.
