These sit in different size classes, so this is not a straight ranking comparison. The Soundboks Rider ranks #31 of 53 party speakers by sound quality at $599; the Sony ULT Field 7 ranks #61 of 113 boombox speakers by sound quality at $448.

What the Soundboks Rider does well: A light, rugged party speaker with a swappable battery that lasts all day at mid volume and an app with a six band EQ. The tradeoff: Its sealed 8in woofer runs out of real bass at high volume: Xander measured the -6 dB point rising to roughly 75 to 85 Hz at maximum, with 40 Hz some 20 dB down, and M1M heard the bass pulled back toward the upper bass above mid volume.
The case for the Sony ULT Field 7: A waterproof stereo party speaker with a 30 hour battery and karaoke mic and guitar inputs. It links with other speakers (Party Connect up to 100 speakers), which the Soundboks Rider cannot. It plays in stereo from a single unit, unlike the Soundboks Rider. Watch for: A peak around 8kHz, and bass does not reach as deep as the top-ranked speakers.
Buy the Soundboks Rider at $599 if you want a party speaker. Buy the Sony ULT Field 7 at $448 if you want a boombox speaker instead.
