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.
NXP® offers a growing portfolio of ultra-low-power MiGLO™ hearables solutions based on digital signal processing (DSP), Near Field Magnetic Induction (NFMI) and Bluetooth Low-Energy (BLE) technologies. MiGLO delivers the power of wireless audio today.
