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.

Though I have yet to hear a MEMS driver for myself, xMEMS says they possess a variety of advantages over existing driver technologies like dynamic, balanced armature, and planar magnetic. These include a huge frequency response range, ultrafast transient response (the ability to quickly shift from from one sound to another), more accurate sound reproduction, and to top it off, they’re tough as nails. With an IP58 rating, they’re fully dust and waterproof and can even withstand being tossed in a washing machine and/or a dryer.

Those are the benefits you and I are told we can enjoy, but for manufacturers, there are additional perks like a high degree of uniformity between drivers because they’re essentially created like microchips.

Why does the Aurvana Ace use two drivers?

In a sealed set of earbuds, like a pair of wired in-ear monitor (IEMs), it’s possible to use a single MEMS driver, but wireless, noise-canceling earbuds are partially vented. That venting exposes one of the few weaknesses of current MEMS driver technology — they can’t produce high enough sound pressure levels (SPL) needed in a vented earbud, especially at the low frequencies used by the majority of active noise cancellation (ANC) algorithms.

That’s why the Aurvana Ace and Ace 2 use a hybrid design — an xMEMS-built driver for the mids and highs, where the MEMS biggest advantages can be heard, and a standard 10mm dynamic driver for the lows, so that the needed SPL is available for ANC to work.

Design-wise, you’d never know that the Aurvana Ace don’t have the same kind of drivers inside as a set of Apple AirPods Pro. With the Ace’s stem-based shape, silicone eartips, and flip-top charging case, they even look a lot like Apple’s earbuds, if you squint your eyes and pretend they’re white.

They also have similar battery and charging specs. Both have wireless charging cases, and both will give you about 24 hours of total listening time.

But when you dig into the details, differences emerge. The Aurvana Ace support Bluetooth 5.3, including LE Audio and compatibility with the new LC3 codec for very low latency. Also supported are SBC, AAC, aptX, and aptX Adaptive when used with compatible phones.

Thanks to the combination of drivers, the Aurvana Ace has a huge frequency response range. Creative claims it’s 5Hz to 40kHz — well above (and below) the normal range of human hearing. The earbuds use hybrid ANC and have six mics for voice pickup during calls. They sport an IPX5 rating for water resistance.

The Ace 2 are nearly identical to the Ace, save for their translucent black plastic and copper-colored charging case inlays.

The bigger difference is that the Ace 2 have two extra Qualcomm technologies built-in: Snapdragon Sound for aptX Lossless for CD-quality audio when used with a lossless audio source and a compatible smartphone, plus Adaptive ANC. Unlike regular ANC, Adaptive ANC can make small adjustments to compensate for any irregularities in the seal between the earbud and your ear, as well as differences in external sounds.

Nura’s personalized earbuds are reborn as the Denon Perl
Denon Perl Pro earbuds.

In April 2023, Denon announced that it had acquired Australian wireless earbud maker, Nura, and that we could expect to see new earbuds from the combined brands "soon." Today, Denon has effectively relaunched Nura's two wireless earbuds -- the NuraTrue and NuraTrue Pro -- as the Denon Perl ($199) and Denon Perl Pro ($349). Denon says a limited number of Denon Perl and Perl Pro headphones are now available for purchase at, with a full rollout planned for later this year.

The Perl and Perl Pro, which Denon has stylized with a capital L (PerL), appear to preserve all of the NuraTrue and NuraTrue Pro's features, and in looking at the new Denon earbuds, it appears that they're also physically identical to Nura's now-discontinued products. One thing that has changed is the price of the NuraTrue Pro. Already fairly expensive at $329, Denon's version is now $20 more.

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.

Skullcandy’s new earbuds mimic the AirPods Pro for just $100

Skullcandy's latest wireless earbuds are packed with features, and in typical Skullcandy fashion, they're priced much lower than the competition. The new Skullcandy Rail ($80) and Rail ANC ($100) look very similar to Apple's AirPods Pro 2, and in the case of the Rail ANC, they possess many of the same features. Both models are available on starting June 13.

Each Rail model uses the same shape and silicone eartips to seal your ear canal, with touch controls on both earbuds, however, the Rail ANC use transparent plastic for the inside half of the earbud, and they have an extra set of microphones.  Here's what you can expect from each Rail version.
