Microsoft may have only announced the Xbox Wireless Headset yesterday, but the company initially showed it during its Xbox Series X|S launch trailer. The company did not reveal any details about the headphones then, but Daniel Kaluuya is undeniably wearing a pair in the video.
While The Verge asserts that Microsoft 'hid' the headset in the advert, calling it a 'cheeky Xbox Easter egg', it seems just as likely that pandemic-related production issues brought about a delay. Phil Spencer did have a Series S on his bookshelf during an interview before Microsoft announced it, but a new console is on a different scale to a pair of headphones.
Microsoft has already made the Xbox Wireless Headset available to pre-order on its website for US$99.99. The headphones will begin shipping on March 16 and are compatible with Xbox Series X|S consoles, Xbox One consoles and PC. Microsoft claims that the headphones will last up to 15 hours on a single charge, but they only support the SBC Bluetooth codec. Hence, the Xbox Wireless Headset does not support the aptX or aptX HD codecs. The headphones do support Dolby Atmos and DTS Headphone:X, though.
The Xbox Wireless Headset charges via USB Type-C, but it is unclear if you can use them over a wired connection. However, the headphones have rotatable dies, like the Surface Headphones 2.
