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.

1More’s PistonBuds Pro Q30 look like great budget buds at $50
1More PistonBuds Pro Q30 in black/gold.

The new PistonBuds Pro Q30 from 1More boast AirPods-like looks along with active noise cancellation (ANC) and spatial audio, but it's their rock-bottom $50 price that stands out. As part of the launch, 1More has dropped the price to $40 for a limited time, making these wireless earbuds even more attractive. The PistonBuds Pro Q30 are available in white/gold or black/gold combos.

In the past, 1More has favored a stemless design for its PistonBuds lineup, but this time the company has opted for a stem-based approach. If you've ever tried PistonBuds in the past and found them a poor fit, this new shape might be a better option.

Your next noise-canceling earbuds may use Navy sonar tech
Two xMEMS Cypress drivers seen sitting on a U.S. dime coin for scale.

A company that is pioneering the use of earbud speakers that are manufactured like microchips says it has developed a way to convert inaudible, high-power ultrasound into hi-fi stereo sound, using a single driver. The result is what the company — called xMEMS —  says is a micro-electromechanical system (with a convenient MEMS acronym) driver that's powerful enough to deliver sound as well as active noise cancellation in a set of wireless earbuds.

According to xMEMS, these MEMS drivers possess a number of advantages for buyers and manufacturers of earbuds, like extreme ruggedness, a huge frequency-response range, ultrafast transient response (the ability to quickly shift from one sound to another), and more accurate sound reproduction.

Creative’s Aurvana Ace are the first wireless earbuds to use MEMS drivers
Creative Aurvana Ace 2 wireless earbuds.

Creative has broken new ground in the wireless earbuds space. The company has announced that its upcoming Aurvana Ace and Aurvana Ace 2 noise-canceling wireless earbuds will use a hybrid dual-driver architecture featuring MEMS drivers from a company called xMEMS, making them the first products of their kind to employ this new audio technology. The Aurvana Ace has been prices at $130 while the Ace 2 is $150. Both will be available for preorder November 10.
What's a MEMS driver?

MEMS stands for micro-electromechanical system -- essentially a tiny device that incorporates both non-moving electronics as well as moving mechanical parts. In the case of the xMEMS-designed audio drivers used in the Aurvana Ace, the moving part is a miniscule silicon membrane that can move air (and thus create sound) when an electrical signal is passed through the flap.
