#24 Harman Kardon Onyx Studio 5: $499.99 Discontinued Amazon eBay

Newer model: the Harman Kardon Onyx Studio 9, ranked higher, rated 4.1/5.

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. Discontinued.

Related speakers: Harman Kardon Onyx Studio 4, Harman Kardon Onyx Studio 6, Harman Kardon Onyx Studio 7, Harman Kardon Onyx Studio 8, Harman Kardon Onyx Studio 9.

How it compares: Just above it: Harman Kardon Go + Play 2 - $150 cheaper. Just below it: Zealot S98 - 3 fewer hours of battery life.
