TWS Developer Kit

True Wireless Stereo (TWS) Development Platform

Knowles has brought together multiple premium component technologies along with acoustic system-level expertise to develop a first-to-market TWS development kit to accelerate TWS innovation with premium and emerging features. With this kit, OEMs gain access to a fully operational TWS development platform, which includes pre-tuned and pre-configured earbuds designed by Knowles paired with a powerful processing platform. The earbuds come designed with multi-microphone arrays, voice vibration sensor, and a choice of premium speaker driver assemblies to drive the development of advanced TWS features while reducing time-to-market and lowering the high costs associated with ground-up development. Knowles has engaged several partners to integrate premium features on this development kit, which enable manufacturers to quickly evaluate features such as Active Noise Cancellation (ANC), ambient mode, premium audio, voice command, voice call algorithms, and AI-enabled conversation enhancement.
