Qualcomm introduces QCC5100 Bluetooth Audio SoC series with Hybrid ANC, voice assistant support

Qualcomm at the CES 2018 introduced Low Power Bluetooth SoC QCC5100 series with support for third-party Voice Assistant Services, Qualcomm TrueWireless Stereo, Qualcomm aptX HD audio and Integrated Hybrid ANC for wireless earbuds, hearables and headsets. Qualcomm also said that it reduces power consumption by up to 65% for both voice calls and music streaming, compared to previous single-chip Bluetooth audio solutions.

The Qualcomm CSR8675 that was introduced at the CES last year powers Google’s Pixel Buds. This has dedicated application processor sub-system, dual DSP architecture and next generation ADK software with enhanced development tools. This offers easy switching between listening to music, making calls, running biometric sensors and using voice assistant services.

Integrated  hybrid ANC reduces the complexity and cost of adding ANC to earbuds offering OEMs to make much smaller headsets.
