Short answer: the JBL PartyBox On-The-Go 2 Plus. It ranks #5 of 113 boombox speakers by sound quality, rated 4.4/5, at $349.95. The Onn Medium Party Speaker Gen 2 ranks #65, rated 3.1/5, at $90, $259.95 cheaper, not enough of a saving to outweigh the sound-quality gap.
The JBL PartyBox On-The-Go 2 Plus is the better-sounding pick. A well balanced karaoke party speaker with clean bass, clear vocals, on-board vocal removal, an included wireless mic and a removable battery. It has an adjustable EQ, which the Onn Medium Party Speaker Gen 2 lacks. The tradeoff: The bass has less kick and physical impact than the JBL Partybox Encore 2 or JBL Partybox Club 120, and the JBL Partybox Club 120 gets noticeably louder.
The Onn Medium Party Speaker Gen 2 is the longer-running, lighter option. 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 15 for the JBL PartyBox On-The-Go 2 Plus. At 11 lbs (5 kg) it weighs noticeably less than the JBL PartyBox On-The-Go 2 Plus at 14.2 lbs (6.45 kg). It is rated IPX7 against IPX4 for the JBL PartyBox On-The-Go 2 Plus. Watch for: Lacking detail compared to the Onn Large Party gen 2 and not as deep of bass.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and saving $259.95 with the Onn Medium Party Speaker Gen 2 does not make up for the sound-quality gap.
