Short answer: the Sonos Play for better sound quality, the Ultimate Ears Megaboom 4 for the lower price. The Sonos Play ranks #50 of 142 medium speakers at $299. The Ultimate Ears Megaboom 4 ranks #137 at $200, $99 cheaper.
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
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.
