Qualcomm Technologies International, Ltd., announced enhancements to its Qualcomm TrueWireless™ Stereo technology today, with the launch of its TrueWireless Stereo Plus. This technology is designed to eliminate all external wires, offering users a cable-free audio experience and support new use cases like hearables.

Qualcomm TrueWireless Stereo Plus allows for a simultaneous connection between the source device and left and right earbuds. This reduces latency and improves connectivity.

The next-generation Qualcomm TrueWireless technology is supported on the recently introduced QCC5100 series breakthrough Bluetooth audio System-on-Chip (SoC), which is designed to help reduce power consumption by up to 65 percent compared to the previous generation. These improvements extend to phones regardless of their smartphone platform. Concerning pairing, users won’t have to pair each earbud individually, making it a more streamlined process. The updates also include the ability to autonomously role switch each earbud between primary and secondary roles in order to balance power consumption between the ‘buds.

This single-chip solution offers manufacturers an efficient way of controlling and managing the truly wireless connection. This is available in a 4mm x 4mm CSP package, along with a comprehensive suite of software (Audio Development Kit) to support the development of new generation, highly compact, feature-rich wireless earbuds and hearables.

The next-generation Qualcomm TrueWireless technology . . . is designed to help reduce power consumption by up to 65 percent.

Qualcomm TrueWireless Stereo Plus eliminates the need for cross-head Bluetooth transmission by simultaneously connecting the mobile device to both earbuds. Only the relevant audio content is engineered to relay to each bud, which improves power consumption while reducing latency. When paired with a QCC5100 series based device and the Qualcomm® Snapdragon™ 845 Mobile Platform, Qualcomm TrueWireless Stereo Plus can help  reduce power consumption by up to 10 percent, typically helping to deliver an extra hour of listening time before recharge is needed.

Designs based on the QCC5100 Series using the enhanced Qualcomm TrueWireless Stereo are expected to be available in the second half of 2018.
