Looking for a single Bluetooth speaker that plays in stereo? A stereo speaker has separate left and right channel drivers in one cabinet, so the instruments a recording places to each side stay apart instead of being folded into one channel. Every pick below is “Stereo: Yes” in our specifications, with the full left and right driver set duplicated; speakers that only split their tweeters while sharing one woofer are left out. See stereo on one speaker explained for what the difference sounds like.
The drivers in one box sit only centimeters apart, so the effect is strongest when you sit close and in front of the speaker. For a full-width stereo image across a room, pair two speakers over TWS instead.

A small speaker’s cabinet is too narrow to separate left and right drivers by much, so nearly every small speaker we rank is mono. The best mono speakers page covers the small size, and the small size ranking lists every one by rating.
