Looking for the best mono Bluetooth speaker? A mono speaker plays both channels of a recording through all of its drivers, so every listener hears the whole mix, whichever side of the speaker they are on. That suits a speaker on a picnic table, in a shower or clipped to a bag, where nobody sits in a stereo sweet spot anyway. Mono is not a sign of a worse speaker: several of the best-rated portables we rank are mono. See stereo on one speaker explained for how the two compare.
If you want stereo later, many mono speakers can pair with a second unit over TWS, which gives a wider stereo image than any single cabinet.
