Qualcomm’s new chipset for wireless earbuds promises improved noise cancellation, all-day battery life
There are now so many wireless earbuds, it’s hard to keep track, but one of the reasons why we’ve seen this explosion in new and existing manufacturers entering this business is the availability of Bluetooth Audio SoCs from Qualcomm, including the QCC5100 and QCC30xx series. Today, the company is launching the latest chipset in its wireless portfolio, the QCC305x.
Unsurprisingly, it’s a more powerful chip, with four more powerful cores compared to the three cores of its 304x predecessor. But the real promise here is that this additional processing power will now enable earbud makers to offer features like adaptive active noise cancellation and support for using wake words to active Alexa or the Google Assistant.
The new chipset now also supports Qualcomm’s aptX Adaptive with an audio resolution of up to 96kHz and aptX Voice for 3-microphone echo canceling and noise suppression for clearer calls while you are on the go (or on a Zoom call, which is more likely these days). And despite the increased power, Qualcomm promises all-day battery life, too, though, at the end of the day, it’s up to the individual manufacturer to tune their gadgets accordingly.
The new chipset has also been designed to support the upcoming Bluetooth LE Audio standard. This new standard hasn’t been finalized just yet, but it promises features like multi-stream for multiple synchronized audio streams from a single device — useful for wireless earbuds — and support for personal audio sharing, so that you can share your music from your smartphones with our people around you. There’s also location-based sharing to allow public venues like airports and gyms to share Bluetooth audio with their visitors.
It’s still early days for Bluetooth LE Audio, but during a press conference ahead of today’s announcement, Qualcomm continuously stressed that its new chips will be ready for it once the standard is ratified.
“Not only do our QCC305x SoCs bring many of our latest-and-greatest audio features to our mid-range truly wireless earbud portfolio, they are also designed to be developer-ready for the upcoming Bluetooth LE Audio standard,” James Chapman, vice president, and general manager, Voice, Music, and Wearables at Qualcomm, said in the announcement. “We believe this combination gives our customers great flexibility to innovate at a range of price points and helps them meet the needs of today’s audio consumers, many of whom now rely on their truly wireless earbuds for all sorts of entertainment and productivity activities.”
