These sit in different size classes, so this is not a straight ranking comparison. The Harman Kardon Go + Play 3 ranks #3 of 112 boombox speakers by sound quality at $385; the JBL Partybox Club 120 ranks #6 of 51 party speakers by sound quality at $399.95.
The Harman Kardon Go + Play 3 is the lighter pick. A stylish stereo boombox with very deep bass for its size and warm sound, made for indoor use. At 10.4 lbs (4.7 kg) it weighs much less than the JBL Partybox Club 120 at 23.8 lbs (10.8 kg). It supports AAC Bluetooth, which the JBL Partybox Club 120 lacks. The tradeoff: Just a little over half as loud as the higher rated boomboxes.
The JBL Partybox Club 120 is the longer-running, tougher option. A party speaker on wheels with quite neutral sound, a removable battery, and mic and guitar inputs. It is rated for 12 hours of battery against 8 for the Harman Kardon Go + Play 3. It is rated IPX4, while the Harman Kardon Go + Play 3 has no water resistance. It links with other speakers (Auracast), which the Harman Kardon Go + Play 3 cannot. Watch for: High price, and JBL’s wired daisy chain only works with other JBL speakers.
Buy the Harman Kardon Go + Play 3 at $385 if you want a boombox speaker. Buy the JBL Partybox Club 120 at $399.95 if you want a party speaker instead.
