On the Harman Kardon Onyx Studio 5 side: Elegant circular design with carrying handle. Set against that: Warm sound with boosted bass.
The case for the Sonos Move 2: Warm sounding with somewhat rolled off treble. The tradeoff: Not very loud.
Buy the Harman Kardon Onyx Studio 5 at $499.99 if you want a boombox speaker. Buy the Sonos Move 2 at $494.99 if you want a large speaker instead.

Sonos Move 2: $494.99 Amazon
Pros: Warm sounding with somewhat rolled off treble. Slightly better midrange clarity than the Move 1.
Cons: Not very loud. This may have some of the same issues at full volume that the Move 1 had too, but I’ll need more sound samples at full volume to verify.
