The truly wireless earbud industry is growing rapidly and consumers are demanding much richer functionality from their devices, so it is important for manufacturers to stay ahead of the curve by bringing innovative new features to market quickly.
The QCC5171 Earbud Reference Design, DK-QCC5171-EARBUDRD-A-0 is designed to provide a flexible development platform for innovation that supports the latest ADK features and helps to reduce development time.
Qualcomm TrueWireless Mirroring
Qualcomm TrueWireless Mirroring with support for dynamic role swapping and single Bluetooth address management.
Integrated Qualcomm ANC Technology
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 Snapdragon Sound™ Technology, Qualcomm® aptX™ Adaptive 24bit/96kHz for high quality, low latency Bluetooth audio streaming.
