Different classes, so treat this as a step-up-or-not question rather than a head-to-head. The Soundcore Rave 3S ranks #20 of 53 party speakers by sound quality at $299.99; the Sony ULT Field 7 ranks #61 of 113 boombox speakers by sound quality at $448.
Why pick the Soundcore Rave 3S: A big party speaker with two wireless microphones, a remote, and a vocal removal feature for karaoke nights. The catch: Some upper bass and upper mids boost.
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 Soundcore Rave 3S. At 13.9 lbs (6.3 kg) it weighs noticeably less than the Soundcore Rave 3S at 21.6 lbs (9.8 kg). It is rated IP67 against IPX4 for the Soundcore Rave 3S. The tradeoff: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the Soundcore Rave 3S at $299.99 for a party speaker, or the Sony ULT Field 7 at $448 for a boombox speaker instead.
