  • Qualcomm announced 2 new Bluetooth audio systems-on-a-chip (SoC) for wireless sound: QCC514X and QCC304X

Qualcomm has announced two new Bluetooth audio systems-on-a-chip (SoC) for wireless headphones: QCC514X and QCC304X. The QCC514X and QCC304X are ultra-low-power chips built for mid-tier and entry-level headphones.

These chipsets will enable a single earbud to connect wirelessly to handsets through Bluetooth and the other earbud can mirror it with Qualcomm’s TrueWireless Mirroring technology. Plus the new chipsets also have active noise cancellation (ANC).

So if a user removes the connected bud from their ear, the mirroring bud is designed for taking 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. And Qualcomm TrueWireless Mirroring was engineered to manage a single Bluetooth address so only one “device” shows up when the user is pairing their earbuds to a phone.

The noise cancellation technology is known as “hybrid ANC,” meaning it also supports outside environmental noise. This is similar to the “transparency” mode built into premium earbuds and headphones.

And the chipsets also have voice assistant support. The QCC514X chipset has always-on voice support while the QCC304X has push-button voice activation.

The QCC514x and QCC304x SoCs were also built for delivering leading power consumption under various use cases with up to 13 hours’ playtime based on 65mAh battery, depending on the settings and other factors.

“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 of Voice, Music & Wearables at Qualcomm Technologies International, Ltd.  “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.”
