These are not really the same size class, and that is the honest framing here. The JBL Partybox 130 ranks #7 of 53 party speakers by sound quality at $449.95; the Sony ULT Field 7 ranks #61 of 113 boombox speakers by sound quality at $448.

What the JBL Partybox 130 does well: A manageable party speaker with balanced, powerful sound, deep bass, a removable battery and a light show. The tradeoff: It is still bass-forward and less clear than the PartyBox 120 in direct comparisons.
The Sony ULT Field 7 is the longer-running, lighter pick. 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 15 for the JBL Partybox 130. At 13.9 lbs (6.3 kg) it weighs much less than the JBL Partybox 130 at 24.9 lbs (11.3 kg). It is rated IP67 against IPX4 for the JBL Partybox 130. The tradeoff: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the JBL Partybox 130 at $449.95 if you want a party speaker. Buy the Sony ULT Field 7 at $448 if you want a boombox speaker instead.
