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 Boombox 3 ranks #27 of 113 boombox speakers by sound quality at $349.95.
Different sizes. The Club 120 is a 23.8 lbs (10.8 kg) party speaker. The Boombox 3 is a 14.8 lbs (6.7 kg) boombox. Each is rated within its own class.
The Club 120 has quite neutral sound with deeper bass than the PartyBox 100 and 110, plus mic and guitar inputs, lights, a 5-band app EQ, Auracast and a removable battery with a claimed 12 hours.
The Boombox 3 is IP67 against the Club 120’s IPX4, claims 24 hours, and measured about 110dB with bass to about 43Hz. It is bass boosted with a mid bass dip, has no EQ, and uses the older PartyBoost linking.
Buy the JBL Partybox Club 120 ($399.95) for a party speaker; the JBL Boombox 3 ($349.95) suits a boombox speaker instead.
