Sonos has been cranking out home audio gear for over a decade, with a product line that spans soundbars, 3.1 and 5.1 home theater setups, smart speakers, and so forth. It doesn't currently offer any high-end headphones, though it is reportedly working on a pair that could see the light of day next year.

Bloomberg spoke with people who claim they are privy to Sonos' plans, and they say a pair of wireless, over-the-ear headphones is already in development, albeit it's in the early stages.
