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.

Denon, which was acquired by Masimo along with sibling Sound United brands Bowers & Wilkins, Polk Audio, and Marantz in 2022, is putting a focus on the Perl and Perl Pro’s proprietary sound personalization technology, called Masimo AAT (Adaptive Acoustic Technology). As far as we can tell, this is simply another rebranding of Nura’s technology that measures “faint otoacoustic emissions (OAEs), which are produced by the inner ear in the presence of a range of tones played to assess each person’s unique response to sound.” Judging from the included images in Denon’s press release, even the Nura app for iOS and Android has been rebranded as part of the Perl launch.

When the NuraTrue Pro launched in 2022, they became the first wireless earbuds to support Qualcomm’s aptX Lossless codec, which promises bit-perfect CD-quality audio under optimal wireless conditions. The Perl Pro maintain that feature. Support for aptX Lossless on the mobile phone side of the equation has been slow to grow — the feature requires a recent version of Snapdragon Sound — but perhaps now that it’s being supported by a legendary audio brand like Denon, we’ll start to see greater adoption.

The Denon Perl have active noise cancellation (ANC), plus a “social mode” (transparency). They have six hours of earbud battery life per charge and three additional charges in the case for a total of 24 hours of power. IPX4 water resistance makes them suitable for workouts or running.

The Perl Pro have an improved ANC system, aptX Lossless support, wireless charging, spatial audio from Dirac, Bluetooth Multipoint, and up to eight hours of battery life in each earbud, plus three more charges in their case, for a total of 32 hours of playback.

Denon’s first wireless earbuds, the $159 Denon Noise Cancelling Earbuds (AH-C830NCW) and the $99 Denon Wireless Earbuds (AH-C630W), debuted in 2021 and will continue to be sold alongside the new Perl models.

Astell&Kern refreshes its UW100 wireless earbuds
Astell&Kern UW100 MK II wireless earbuds held in hand.

We're guessing Astell&Kern (A&K) must have been pretty happy with how its first wireless earbuds -- the A&K UW100 -- worked out because the company has just announced a second generation and you'll need to look very closely to find the changes. The Astell&Kern UW100 MK II will be available in September for the same $299 price as the original.

On the outside, the MK II look exactly the same as their predecessors. A&K has kept the same two-tone, rounded pentagon shape, which, while a bit on the big side, has still proven to be quite comfortable. Even the internal components are unchanged -- A&K has kept the single full-range Knowles balanced armature (BA) driver, which it powers using a combo of its own amp technology and an Asahi Kasei AKM 32-bit Hi-Fi digital-to-analog converter (DAC). The earbuds make use of Qualcomm's aptX Adaptive Bluetooth codec to deliver up to 24-bit/96kHz hi-res audio when used with a compatible Android smartphone.

Updating our Sony WF-1000XM5 review
Sony WF-1000XM5 in silver.

As the Barenaked Ladies famously sang, it's been one week. One week since Digital Trends and the rest of the techno-review world published the first reviews of the Sony WF-1000XM5 wireless noise-canceling earbuds. Or at least, these were supposed to be the first reviews. As it turned out -- and at first unbeknownst to any of these publications -- Sony didn't send out full production versions of the XM5. Though they looked exactly like the earbuds that you can buy today, they were unfinalized prototypes. We were clear about that at the time, and we want to be as transparent about things now.

Once Sony confirmed we'd initially been given prototype units, we published a sort of placeholder review that was heavily caveated to explain the situation to readers. One week later, Sony sent out full production XM5 units, and we've since updated our review with our final thoughts using production units — the same as what you can buy today. (Spoiler: The production units solved all the problems we saw with the prototypes.)

Sony updates WH-1000XM5 with head-tracked spatial audio and better multipoint

Sony has released a software update for its flagship noise-canceling headphones, the WH-1000XM5, that enables head-tracked spatial audio -- a feature the company first debuted this week on its new WF-1000XM5 wireless earbuds.

The update also includes an enhancement of how Bluetooth Multipoint works on these wireless headphones. Previously, you had to choose between connecting two devices to the XM5 simultaneously or being able to use the company's LDAC hi-res Bluetooth codec. Turning on one of these features would automatically disable the other. Now, you can leave LDAC enabled and take advantage of simultaneous connections, even if one of the devices isn't LDAC-capable (like an iPhone).
