The Two Speakers In Full
Harman Kardon Onyx Studio 5: $499.99 Amazon eBay
Pros: The iconic circular cabinet and integrated handle make it an attractive room-to-room speaker. Reviews praise its generous bass, balanced mids and smooth top end at moderate levels, giving it a warm, relaxed presentation for casual indoor music.
Cons: The large bass boost can mask lower-mid detail and make dense mixes muddy. Battery life is only around eight hours at moderate volume, it is not especially loud, and it has no water resistance for outdoor use.

Sonos Move 2: $494.99 Amazon eBay
Pros: Warm sounding with somewhat rolled off treble. Slightly better midrange clarity than the Move 1.
Cons: Not very loud. It may share the Move 1’s full-volume issues, though more sound samples at full volume are needed to confirm that.
