Qualcomm TrueWireless™ Mirroring

Innovative Qualcomm TrueWireless™ Mirroring technology is designed to deliver a superior user experience by improving robustness and supporting dynamic and seamless bud-to-bud role-swapping with Bluetooth address handover even during run time. True Wireless Mirroring also supports balancing out power distribution between both earbuds.

Support for multiple voice ecosystems

The QCC5151 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.

Support for Bluetooth Low Energy Audio

Designed to support the forthcoming LE Audio standard and new user experiences with end-to-end operability from smartphone to earbuds. This SoC is designed to help early-adopting manufacturers develop truly wireless earbuds that deliver the audio sharing use cases supported by the exciting LE Audio standard.
