Bang & Olufsen’s latest headphones offer improved ANC and a 35-hour battery

Bang & Olufsen Beoplay HX

Bang & Olufsen (B&O) has taken the wraps off its latest high-end wireless headphones, the $499 Beoplay HX, which go on sale today in its black anthracite color scheme. Two other colors, sand and timber, will be made available later this year.

The Beoplay HX is the latest in the company’s line of luxury wireless headphones. It follows the $499 Beoplay H9 and the more recent $800 Beoplay H95. The HX’s key feature is an improved form of active noise cancellation (ANC), which B&O calls its “next generation of Digital Adaptive Active Noise Cancellation.” The HX is equipped with four microphones for ANC, two of which are shared for voice calls.

When we reviewed the H9, we noted that their ANC was not especially strong at dealing with outside sounds. “It was actually a bit hard to tell where the active noise canceling began and the passive noise isolation ended at times,” our reviewer observed. Hopefully, the HX’s new ANC system proves more effective. All of the HX’s settings including ANC and transparency modes can be adjusted with the B&O app.

Inside the aluminum-finished earcups is a set of 40mm drivers with bass ports, which B&O promises will deliver optimal bass performance.

Powering the headphones is a battery with a claimed 35-hour life with ANC turned on, and 40 hours when it’s not in use. That’s a decent boost over the original Beoplay H9, which claimed a 20-hour battery life but only delivered about 14 hours with ANC turned on. Thirty-five hours is also significantly more than you’ll get from the $399 Bose Noise Canceling Headphones 700 or the $549 Apple AirPods Max.  Unlike the H9, the HX’s battery isn’t removable.

The H9’s materials and build quality were top-notch and B&O appears to have kept this tradition alive with the HX. There’s plenty of supple leather used on both the ear cushions and the headband, and recycled aluminum is employed for the earcup pivots and sliders. The HX might actually be more comfortable for longer periods thanks to a revised headband design that uses a new center-relief zone channel.

Another feature that has stuck around is B&O’s touch controls, located on the right earcup. We’re hoping these have been improved since the H7 and H9, both of which gave our reviewer some problems: “The touch controls remain glitchy; there’s often latency with playback controls, and while swiping left and right works for changing songs, we routinely paused music when we were trying to swipe in a circular motion to adjust volume.”

Rounding out the HX’s feature list is Bluetooth 5.2, Google Fast Pair, Microsoft Swift Pair, multipoint capability for connecting with two source devices at once, a 3.5mm analog line-in jack, and support for SBC, AAC, and aptX Adaptive codecs.

Dali says its latest wireless headphones achieve electrostatic levels of clarity
Dali IO-12 wireless headphones.

Dali's latest wireless headphones, the Dali IO-12, will cost $1,299 when they hit retail later this month. That's a huge jump up from the company's previous offering, the $500 Dali IO-6, and it might even be a new record price for a set of wireless headphones, but Dali says the new noise-canceling cans are worth it because of the unusual technology that has been used to create the headphones' 50mm drivers.

The Danish company claims the IO-12 are the world's first to use a Soft Magnetic Compound (SMC) magnet system -- the same tech that Dali patented and used in its acclaimed floor-standing speakers. The primary benefit to SMC is a reduction of hysteresis -- distortion that can be caused by resistance to the voice coil in traditional magnet systems. Reducing hysteresis can lower uneven harmonic distortion "drastically," according to Dali.

Sennheiser’s new budget-friendly headphones get a very high-end feature
Sennheiser Accentum wireless headphones in black and white colors.

Sennheiser's new Accentum wireless noise-canceling headphones look a lot like its top-of-the-line $380 Sennheiser Momentum 4 Wireless headphones. And while they have similar features, the Accentum are priced at $180 and can do something the Momentum 4 can't: they accept lossless digital audio via their USB-C port. The black version is up for preorder on September 25 and is expected to ship starting on October 4, while the white version begins shipping in late November. Both models will be available at select retailers and at

The Accentum are the successors to Sennheiser's 2020 HD 450 BT, and the company's approach to this more affordable product line remains the same -- preserve as many features from the Momentum line as possible while keeping the price under $200. Needless to say, you can't do this without some trade-offs. The Accentum don't come with a carry case or any kind of analog input. They use only physical controls, not touch controls, and they don't have wear sensors for auto-pausing your tunes when you remove them.

Marshall updates its noise-canceling earbuds with better battery life
Marshall Motif II ANC in charging case.

Marshall's second-gen Motif ANC wireless earbuds -- appropriately called the Marshall Motif II ANC -- look exactly like the first-gen Motif, but under the hood are some welcome enhancements like better battery life, better active noise cancellation (ANC) performance, and support for Bluetooth LE Audio. The price, on the other hand, remains the same: you can buy them staring August 29 for $199 on Marshall's website. The company expects them to ship on September 12.

Marshall has a talent for understatement. Its press release for the Marshall Motif II ANC talks about the improved battery life twice -- the new earbuds now get six hours of ANC playtime on a charge and a total of 30 hours with the case (versus 4.5 and 20 on the first-gen) -- but never mentions that the new Motif now have Bluetooth Multipoint for connecting two devices simultaneously.
