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 QCC3046 offers support for push button activated digital assistants, for multiple ecosystems. This helps OEMs to quickly, cost effectively and efficiently add voice assistant capability to mid and entry-level earbuds.
