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 JBL Partybox On the Go ranks #67, rated 3.0/5, at $329.95, $20 cheaper, not enough of a saving to outweigh the sound-quality gap.
The new model is a big step up. The original On-The-Go’s sound trails the rest of the PartyBox line, with bass limited to about 49Hz, no EQ and a claimed 6 hours of battery. The On-The-Go 2 Plus is well balanced with strong vocals and clean bass, with dome tweeters, app EQ, bass boost modes and a claimed 15 hours from a removable battery.
Karaoke gets smarter. Both include a wireless microphone. The 2 Plus adds EasySing AI vocal removal that strips vocals from any song on the speaker itself.
Weight drops from 16.5 lbs (7.5 kg) to 14.2 lbs (6.45 kg), and the 2 Plus adds a padded shoulder strap, USB-C playback and charging, and Auracast. Both are IPX4.
Buy the JBL PartyBox On-The-Go 2 Plus. It is rated higher for sound quality, and the $20 you would save on the JBL Partybox On the Go does not close the gap.
