Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The JBL Partybox Club 120 ranks #6 of 53 party speakers by sound quality at $399.95; the JBL PartyBox On-The-Go 2 Plus ranks #5 of 113 boombox speakers by sound quality at $349.95.
The Club 120 is louder with more bass. Its two woofers give it noticeably more output and the most thunderous bass of the two, and it is quite neutral for a party speaker. The On-The-Go 2 Plus sounds well balanced with cleaner, smoother bass that has less kick.
The On-The-Go 2 Plus is easier to carry, at 14.2 lbs (6.45 kg) with a shoulder strap against 23.8 lbs (10.8 kg) for the Club 120 with wheels and a handle. Both use the same removable 34Wh battery. JBL claims 15 hours for the On-The-Go 2 Plus and 12 for the Club 120.
For karaoke, the On-The-Go 2 Plus includes a wireless mic and EasySing AI vocal removal but has no wired inputs. The Club 120 has wired mic and guitar inputs, and can add JBL’s EasySing mics for vocal removal too. For more than one singer, the Club 120 with EasySing mics is the more flexible setup.
Both are IPX4 with Auracast and lights.
Buy the JBL Partybox Club 120 at $399.95 for a party speaker, or the JBL PartyBox On-The-Go 2 Plus at $349.95 for a boombox speaker instead.
