Microphone-less Sonos Arc SL soundbar arrives exclusively at Costco

Sonos has quietly begun selling a new version of its Dolby Atmos-enabled Arc soundbar that comes without a built-in microphone, although you’ll have to venture out to Costco to snag one. The Sonos Arc SL Shadow Edition is now available exclusively at “participating” Costco stores in the U.S. and Canada, and it will be available on Costco.com
