Anker Soundcore says its new wireless buds will block up to 98% of external noise

Anker’s Soundcore division has got a new set of wireless earbuds. And while the name may sound familiar — they’re called the Liberty 4 NC — their price is a nice surprise: just $100. That buys you a set of hi-res-capable wireless earbuds that Anker claims have really impressive active noise cancellation (ANC) and battery life.

Anker calls it “Adaptive ANC 2.0” a system that uses two mics — one inside your ear and one on the outside of the earbuds — to adapt ANC performance instantly in any environment. The company must be confident that the system works well; it claims it blocks out up to 98.5% of external noise. Not even the superb Apple AirPods Pro 2 claim that kind of performance.

We’re not sure if these numbers are with ANC on or off, but the Liberty 4 NC supposedly offer a huge 60 hours of total playtime, with 10 hours of use per charge in the earbuds and an additional 50 hours hidden in the charging case. That’s a big jump over the $150 Soundcore Liberty 4 (nine hours per charge, 28 hours total).

We also don’t know exactly how the use of Sony’s hi-res LDAC Bluetooth codec will affect these numbers (it will definitely reduce them), but the feature is included if you happen to have an Android phone.

So the Liberty 4 NC have a new ANC system and better battery life than the Liberty 4, yet they cost $50 less? It makes you wonder what you’ll be giving up.

Anker hasn’t provided the full Liberty 4 NC specs yet — technically the product won’t be released until the end of June — but we can see from the provided photos that Soundcore has moved away from the fancy sliding lid design for the charging case, opting for a simpler (and presumably cheaper) traditional hinge.

The Liberty 4 NC will be available in five colors at launch: white, light blue, navy blue, pink, and black, and Anker promised they’ll come packaged in a 98% plastic-free box with 100% recyclable materials.

It’s not clear whether the Liberty 4 NC will support wireless charging or Bluetooth Multipoint, or whether it has built-in wear sensors for auto-pausing music — all things that you get with the Liberty 4. We also don’t know if the NC version will have spatial audio with head-tracking or a heart rate monitoring feature — again, both are available on the Liberty 4.

Still, even if Anker omits spatial audio and fitness tracking, there’s still tons of value left when you consider the price.

JLab sets a new low price for noise-canceling wireless earbuds

Not long ago, active noise cancellation (ANC) in a set of wireless earbuds was a pricey proposition, with companies like Bose and Sony charging hundreds of dollars for the privilege of peace and quiet. Today, ANC is within reach of just about everyone. That's especially true in light of JLab's announcement of the Go Pop ANC, which it claims are "the most affordable true wireless earbuds with active noise cancellation." The tiny noise canceling buds come in three color options, and they're priced at just $30 -- only $5 more than the non-ANC version.

While ANC (and the price) are definitely the headlines on the Go Pop ANC, the earbuds have several other features that make them worth a look:

Soundcore’s Liberty 4 Pro earbuds debut with a slick smart case and a killer price
Soundcore Liberty 4 Pro.

Soundcore's latest flagship noise-canceling wireless earbuds are packed with all of the latest tech you might expect, including a sleek and smart charging case with its own display screen. But their price is the real headline: The Soundcore Liberty 4 Pro are just $130. While many manufacturers are increasing prices because of inflation, somehow the Liberty 4 Pro are less expensive than the two generations that preceded them. They're available starting October 3 on Amazon in white, light blue, and black color options.

Though they're the latest version of the Liberty Pro family, the Liberty Pro 4 have ditched the stemless designs of the lineup's second- and third-gen models in favor of the stem-based shape Soundcore has used on its other recent models like the Liberty 4 and Liberty 4 NC.

Sony builds on LinkBuds brand with Fit, Open, Speaker — and Olivia Rodrigo
Sony LinkBuds Open, regular and Olivia Rodrigo editions.

Sony today announced a trio of new products in its LinkBuds line. (One of which really isn't what you'd consider when you hear "buds," but we'll get to that in a minute.) Building on the 2022's LinkBuds and LinkBuds S, the new LinkBuds Fit and LinkBuds Open are still of the earbud variety, matching fit and style with design and function. Sony's adding the LinkBuds Speaker, too, which features some special pairing with the new buds, as well as a couple other Sony headphones.

And, yes, after a successful collaboration with the LinkBuds S in 2023, Olivia Rodrigo (who must always be referred to by both names, my teenage daughters tell me) is back for more.
