Qualcomm Technologies International has announced its next generation of ultra-low-power Bluetooth SoCs, optimized for use in true wireless earbuds and hearables.

The Qualcomm QCC514X (premium tier) and QCC304X (entry/mid-tier) SoCs are designed to enable improved robustness and connectivity, increased battery life and comfort, integrated dedicated hardware for Hybrid Qualcomm Active Noise Cancellation (Hybrid ANC), voice assistant support, said the vendor.

"Customers rely on us to help them deliver premium sound with long battery life and robust truly wireless connectivity, even in congested environments, and this exciting new Qualcomm TrueWireless Mirroring technology is designed to deliver on those vital features when using wireless earbuds and headphones," said James Chapman, vice president and general manager, Voice, Music & Wearables, Qualcomm Technologies International. "We have added voice assistant support at all tiers as well as integrated digital Hybrid ANC without compromising power consumption which further allows these new SoCs to deliver amazing experiences."

These new solutions now support the Qualcomm TrueWireless Mirroring technology. With Qualcomm TrueWireless Mirroring, one earbud is wirelessly connected to the phone via Bluetooth while the other bud mirrors the connected bud and is engineered to deliver a rapid swap under several scenarios, according to the company. For example, if the user removes the connected bud from their ear, the mirroring bud is designed to take over the connection to the phone, to avoid any interruption of streaming music or an active voice call with no action required by the user. Qualcomm TrueWireless Mirroring is also engineered to manage a single Bluetooth address so only one "device" shows up when the user is pairing their earbuds to a phone.

The new SoCs also boast integrated Hybrid ANC technology. The dedicated ANC hardware integrated in the SoC enables super-low latency leak-through of the outside environment to allow for truly natural awareness of the surroundings, making ANC not just for airplane use, but applications in sports, office environments and other places throughout the user's day, said Qualcomm. The QCC514x and QCC304x SoCs are also optimized to deliver leading power consumption under various use cases, with up to 13 hours' playtime based on 65mAh battery, depending on settings and other factors.
