Qualcomm TrueWireless Mirroring

Qualcomm TrueWireless Mirroring with support for dynamic role swapping and single Bluetooth address management

Integrated Qualcomm ANC Technology

Our breakthrough ultra-low power ANC (Active Noice Cancellation) is designed to help provide high quality immersive experiences while at the same time, to enable natural leak-through of noise to allow for awareness of surroundings. Our ANC is totally integrated into this single-chip solution, helping to reduce the complexity, cost, and PCB space of adding ANC to earbuds and hearables by eliminating the need for a separate ANC chip.

Quality audio technologies

Support for Qualcomm aptX Adaptive audio technology for high quality, low latency Bluetooth audio streaming.
