Short answer: the Harman Kardon Onyx Studio 7. It ranks #14 of 112 boombox speakers by sound quality, rated 4.1/5, at $248.90. The Onn Medium Party Speaker Gen 2 ranks #65, rated 3.1/5, at $90, $158.90 cheaper, which does not close the gap in sound quality.
The Harman Kardon Onyx Studio 7 is the better-sounding, lighter pick. An elegant home portable with warm, spacious sound, strong deep bass, and stereo pairing with a second unit. At 6.4 lbs (2.9 kg) it weighs much less than the Onn Medium Party Speaker Gen 2 at 11 lbs (5 kg). The tradeoff: Consumer Reports finds the bass prominent and boomy, mids hazy, treble slightly smeared and the soundstage congested.
The Onn Medium Party Speaker Gen 2 is the longer-running, tougher pick. An affordable waterproof party speaker with a big woofer, lights, a karaoke mic input and FM radio. It is rated for 20 hours of battery against 8 for the Harman Kardon Onyx Studio 7. It is rated IPX7, while the Harman Kardon Onyx Studio 7 has no water resistance. Watch for: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
Buy the Harman Kardon Onyx Studio 7. It is rated higher for sound quality, and the $158.90 you would save on the Onn Medium Party Speaker Gen 2 does not close the gap.
