These are not really the same size class, and that is the honest framing here. The JBL Partybox Club 120 ranks #6 of 50 party speakers by sound quality at $349.95; the Sony ULT Field 7 ranks #60 of 111 boombox speakers by sound quality at $448.
The case for the JBL Partybox Club 120: A party speaker on wheels with quite neutral sound, a removable battery, and mic and guitar inputs. The catch: Its 40Hz to 20kHz (Manufacturer specified) specification points to limited deep-bass reach for the cabinet size.
The Sony ULT Field 7 is the longer-running, lighter option. A waterproof stereo party speaker with a 30 hour battery and karaoke mic and guitar inputs. It is rated for 30 hours of battery against 12 for the JBL Partybox Club 120. At 13.9 lbs (6.3 kg) it weighs much less than the JBL Partybox Club 120 at 23.8 lbs (10.8 kg). It is rated IP67 against IPX4 for the JBL Partybox Club 120. Watch for: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the JBL Partybox Club 120 at $349.95 if you want a party speaker. Buy the Sony ULT Field 7 at $448 if you want a boombox speaker instead.
