Short answer: the Sonos Play if sound quality matters most, the Ultimate Ears Wonderboom 4 if price matters most. The Sonos Play ranks #50 of 142 medium speakers at $299. The Ultimate Ears Wonderboom 4 ranks #87 at $59.99, $239.01 cheaper.
What the Ultimate Ears Wonderboom 4 offers: Small size. Watch for: Bass isn’t as deep as the top-ranked speakers and is a little thuddy. Not much improvement over the previous Ultimate Ears Wonderboom 3 besides the USB-C charging port.
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. 24-hour user-replaceable battery with an included wireless charging base, IP67 waterproof and dustproof, and full Sonos WiFi multi-room with AirPlay 2 on top of Bluetooth 5.3. Watch for: 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.
Buy the Ultimate Ears Wonderboom 4 if the price matters more than sound quality. Buy the Sonos Play if sound quality matters more than the price.
