Overview
Hearables or smart headphones are highly integrated, truly wireless earbuds designed to improve audio experiences across a range of consumer and healthcare applications.
Small form factors, ultra-light weight and wireless operation increase user comfort. The continued challenge for hearables is how to combine audio quality, user experience and better battery life in a tiny package while offering a multitude of possibilities, all of which demands digital signal processing.
To simplify customer engineering efforts on prototype TWS earbud, NXP built an Application Development Kit. Customer just need plug and play to test the functionality and performance of earbud.
The ADK demonstrated a stable audio streaming link from Bluetooth mobile phone to both ear. It can be used as a fundamental platform for customer to develop hearables.
