The company claims that the headphones use a new Bluetooth audio SoC-it didn't specify which-and an updated algorithm for its own QN1 noise-cancelling chip to update and process noise cancelling in real time.
Updated ANC and noise processingįurther Reading Guidemaster: The most useful gadgets to have in your bag while travelingThough the active noise cancellation (ANC) on the XM3 was close to best in class, Sony says it has improved upon the tech with the XM4. At the same time, they still provide a just-firm-enough seal to keep too much outside noise from seeping in. They still aren't as light as something like Bose's QuietComfort 35 II, but there's enough cushioning and space here to feel agreeable for hours at a time. Comfort was not a general area of concern with the XM3, and so far I've had no major complaints wearing the XM4 for extended periods. Sony says it has made some slight design tweaks to accommodate more head and ear sizes, though: the headband is slightly less padded but also a tinge wider, while the earpads are said to have a 10-percent larger surface area. There's still a set of touch-based controls on the right earcup instead of physical playback buttons. The earcups still fold up for easy storage, there's still a USB-C port for charging, and the device can still work over an included 3.5mm cable in a pinch. The design is nearly identical to its predecessor: we're still looking at a largely handsome design with a plastic yet sturdy and smooth finish, which is available in black or silver with copper accents. In general, the idea behind the XM4 is one of refinement more than radical reinvention. I've had the XM4 on hand for the past couple of days I plan to have a more detailed comparison in the near future, but for now I can share some initial impressions alongside today's news. The headphones cost $350, which is the same price as the XM3 at launch and Bose's competing QuietComfort 35 II, but $50 less than Bose's Noise Cancelling Headphones 700. The XM4 is available for pre-order starting today, with shipping to start sometime in "mid-August," according to Sony. The new over-ear cans are the follow-up to Sony's WH-1000XM3, which have been widely regarded as being among the best premium pairs of noise-cancelling headphones on the market-and have been an Ars favorite-since launching in 2018. Sony on Thursday announced its latest flagship pair of wireless noise-cancelling headphones: the WH-1000XM4.
