All-day battery life and ANC are about to become standard true wireless features

Simon Cohen
By

Qualcomm, the company that makes a significant number of the tiny chips that give Bluetooth devices their wireless capabilities, has just announced its latest SoCs (system-on-a-chip): The Qualcomm QCC514X and Qualcomm QCC304X. And though you will likely never run across these names or model numbers as you’re shopping for a new set of wireless headphones or true wireless earbuds, they’re about to have a profound impact on what those gadgets can do and how much they’ll cost.

ANC for all

Perhaps the most significant change these new chips will bring is active noise cancellation (ANC). ANC has been a popular feature in wireless headphones and has recently made its way into true wireless earbuds too. Unfortunately, it tends to be found only on the most expensive models like Apple AirPods Pro ($249) and Sony WF-1000XM3 ($199-230).

With Qualcomm’s new chips, ANC is built-in, which means that manufacturers won’t have to go to the trouble (time and money) of integrating their own proprietary ANC technologies to offer this feature. In as little as a year, we could see ANC go from being a premium feature to something that appears on true wireless earbuds at almost every price.

Better wireless

Currently, Bluetooth true wireless earbuds must typically share a single wireless connection back to your phone. One earbud is always the primary and it shares the connection over its own wireless link to the secondary earbud. The problem with this arrangement is that the primary earbud might not always have the strongest connection to your phone, or, you may want to use the secondary bud on its own.

Either way, this can result in bad or zero connectivity. Qualcomm’s latest chips use the company’s TrueWireless Mirroring tech, which alleviates this problem by automatically transferring the primary wireless connection between the two earbuds, effectively eliminating the whole idea of primary and secondary. True wireless earbuds that use these chips will let you use just the left earbud, just the right one, or both, without worrying about dropped connections.

Go hands-free

One of the coolest innovations in the true wireless space from the past two years is Apple’s H1 wireless chip. Among other benefits, it enables hands-free access to Siri, Apple’s voice assistant. The only other company to offer a similarly hands-free option is Amazon via its Echo Buds — but that only extends to Alexa.

True wireless earbuds that embed Qualcomm’s more expensive chip, the QCC514X, will get this functionality, and it won’t be limited to a single voice assistant. Earbuds that use the less expensive QCC304X can also grant voice assistant access, but you’ll need to press or tap a button to do so.

Go all-day

One weakness that has plagued even the most expensive true wireless earbuds is a lack of decent battery life. Recently, we’ve seen some models — like the Samsung Galaxy Buds+ and the Master and Dynamic MW07 Plus — achieve up to 11 hours before needing to be popped back in their charging cases, but these are still rarities.

If Qualcomm’s claims for its new chips are accurate, we could soon see true wireless earbuds that deliver truly all-day performance, with up to 13 hours between charges. Throw in the extra capacity of the charging cases and that should extend the total time to almost 40 hours, assuming the case holds two full charges (most cases hold more than that).

When will we start to see new true wireless earbuds that include the latest Qualcomm chips? Given all of the uncertainty at the moment, that’s a tough thing to predict. Still, it wouldn’t surprise us if the first models appeared in time for the 2020 holiday season. We’ll let you know as soon as we spot them!

Jabra’s $100 Elite 4 are its most affordable ANC earbuds yet
The Jabra Elite 4 true wireless earbuds.

Jabra today launched the latest member of its flagship Elite line of true wireless earbuds, the step-up Elite 4. Picking up where the popular Jabra Elite 3 left off, the $100 earbuds aren't a huge departure, but add some key new features, such as active noise cancellation (ANC), Bluetooth multipoint connectivity, and Swift Pair linking with Windows PCs.

Jabra's Elite line of true wireless earbuds are top performers for the brand (and some of the best earbuds around, period), with several models of them landing on our top earbud lists over the years, including the stellar Elite 7 Pro and the Elite 85t. Sitting at the more affordable end of Jabra's lineup, 2021's Elite 3s were a great-sounding pair of super-comfortable earbuds with easy-to-use physical controls on each bud, and a wide range of customizable features through the Jabra Sound+ app.

Bowers & Wilkins’ wireless earbuds get better battery life and longer range
Bowers & Wilkins Pi5 S2.

Bowers & Wilkins (B&W) has released new versions of its two models of noise-canceling earbuds: the Pi5 S2 ($299) and Pi7 S2 ($399). They're available starting January 25 and feature small but welcome improvements to their predecessors, the PI5 and PI7, which launched in 2021. The company says both new models have improved battery life and better Bluetooth connectivity.

The earbuds now come in new color options. The Pi7 S2 are available in Satin Black, Canvas White, and Midnight Blue. The Pi5 S2, which has seen a $50 price increase from the PI5, come in three new color options at launch: Cloud Gray, Storm Gray, and Spring Lilac, with a fourth color -- Sage Green -- coming later this spring.

KEF takes a swing at Bose, Sony, and Sennheiser with its first wireless ANC headphones
KEF Mu7 wireless noise-canceling headphones.

KEF, the British audio brand best known for its high-end speakers, has launched the Mu7, its first set of premium, wireless noise-canceling headphones. They're priced at $400 and come in two slightly different color tones: silver gray, and charcoal gray. For the moment, they're only available at KEF's website.

The Mu7 are very distinctive, with a design created by Ross Lovegrove, who collaborated with KEF on its first set of wireless earbuds, the Mu3. In fact, the Mu7 look like a scaled-up version of the Mu3, with a similar smooth-oval shape for the earcups and plenty of aluminum used throughout the headphones. The design mirrors other high-end wireless headphones with a fold-flat set of hinges, but KEF only includes a carry "pouch" instead of the nearly standard zippered carry case.
