Short answer: the Sonos Play if sound quality matters most, the Sony ULT Field 3 if price matters most. The Sonos Play ranks #48 of 137 medium speakers at $299. The Sony ULT Field 3 ranks #58 at $148, $151 cheaper.
What the Sonos Play offers: Genuinely wide, clean stereo dispersion off-axis thanks to the two angled tweeters, holding up from the side far better than most portables. Loudness processing keeps it sounding full-bodied at low volume. The catch: Bass distorts noticeably on bass-heavy tracks at default settings, and the distortion persists even after enabling Trueplay tuning and manually pulling bass back in the app. Sounds boxy and short on clarity next to cheaper competitors.
The case for the Sony ULT Field 3: IP67 rated, dustproof and water resistant. 24 hour battery life. App with 10-band EQ. Party Connect with up to 100 speakers. USB-C in/out for charging your phone. Set against that: Sounds a bit hollow, a bit boosted in the treble. Custom EQ and the ULT bass-boost button can’t be used together - turning on ULT disables the EQ. Bass is very weak with ULT off.
Buy the Sonos Play if sound quality is the priority over the price, or the Sony ULT Field 3 if the price is the priority over sound quality.
