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 4 ranks #20 of 113 boombox speakers by sound quality at $549.95.
What the JBL Partybox Club 120 does well: A party speaker on wheels with quite neutral sound, a removable battery, and mic and guitar inputs. It keeps a wired aux input, which the JBL Boombox 4 lacks. It has a microphone input for karaoke or announcements, which the JBL Boombox 4 lacks. The tradeoff: High price, and JBL’s wired daisy chain only works with other JBL speakers.
The JBL Boombox 4 is the longer-running, lighter option. An extremely loud boombox for its size with fully waterproof, dustproof build, a long battery and a flexible app EQ. It is rated for 28 hours of battery against 12 for the JBL Partybox Club 120. At 13.2 lbs (5.98 kg) it weighs much less than the JBL Partybox Club 120 at 23.8 lbs (10.8 kg). It is rated IP68 against IPX4 for the JBL Partybox Club 120. The catch: Pretty overpriced for the category.
Buy the JBL Partybox Club 120 ($399.95) for a party speaker; the JBL Boombox 4 ($549.95) suits a boombox speaker instead.
