Short answer: the Sonos Play if sound quality matters most, the Ultimate Ears Wonderboom 2 if price matters most. The Sonos Play ranks #56 of 177 medium speakers, rated 3.5/5, at $299. The Ultimate Ears Wonderboom 2 ranks #110, rated 2.9/5, at $80, $219 cheaper.
The Ultimate Ears Wonderboom 2 is the lighter option. A small waterproof speaker that floats and is light enough to toss in a bag for the pool or beach. At 0.9 lbs (420 g) it weighs much less than the Sonos Play at 2.9 lbs (1.3 kg). The catch: Not stereo, barely any bass, recessed treble.
The Sonos Play is the better-sounding, longer-running choice. A Wi-Fi and Bluetooth portable with wide stereo sound, a long lasting swappable battery, waterproofing and full Sonos multiroom support. It is rated for 24 hours of battery against 12 for the Ultimate Ears Wonderboom 2. It keeps a wired aux input, which the Ultimate Ears Wonderboom 2 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Wonderboom 2. 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.
Buy the Ultimate Ears Wonderboom 2 when the price outweighs sound quality for you, and the Sonos Play when sound quality outweighs the price instead.
