The latest member of Microsoft's steadily-growing Surface family is a pair of noise-cancelling headphones, predictably christened Surface Headphones and rolling together everything the Windows colossus can squeeze over your ears in these admittedly chunky muff-like cans.
This starts with Bluetooth for a cordless tangle-free experience – including Microsoft's Swift Pair for connection to Windows 10 devices – although there's also a conventional audio jack.
The degree of noise-cancellation is variable, with a turn of a seamless dial on the earcup swinging between 13 levels to blot out as much ambient sound as you desire, rather than the usual on/off setting.
Slipping off the headphones automatically pauses music playback or mutes your phone call, with things picking up again once you put the cans back on.
Microsoft's Cortana voice assistant is baked in, while a pair of beam-forming microphones on each earcup should make for a sharp phone calls and Skype sessions.
Battery life is rated at 15 hours if you're streaming music via Bluetooth, running noise cancellation and using Cortana, with more time per tank if you dial back any of those features.
The battery can be fully charged in two hours over USB-C, with Microsoft promising that even five minutes' of fast-charging will deliver an hour of listening.
Microsoft's Surface Headphones will be released in the US before Christmas at US$349, but aren't expected to hit Australian shelves until sometime in 2019.
