Integrated Qualcomm Active Noise Cancellation Technology

Our breakthrough ultra-low power ANC is designed to help provide high quality immersive experiences while at the same enabling 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.

Qualcomm TrueWireless™ Mirroring

Innovative new Qualcomm TrueWireless™ Mirroring technology is designed to further improve robustness and support dynamic and seamless bud-to-bud role-swapping with Bluetooth address handover even during run time while also balancing out power distribution between both earbuds.

Support for multiple voice ecosystems

The QCC5144 offers support for push button and wake word activated digital assistants, for multiple ecosystems. This can help to accelerate commercialization of voice-activated products and reduce integration and development time for device manufacturers by combining local voice recognition algorithms running on the Bluetooth audio platform with cloud services running on a mobile application.
