Short answer: the B&O Beosound A1 2nd gen. It ranks #11 of 177 medium speakers by sound quality, rated 4.3/5, at $395. The Sonos Play ranks #56, rated 3.5/5, at $299, $96 cheaper, a saving that is not big enough to make up the sound-quality gap.
The B&O Beosound A1 2nd gen is the better-sounding, lighter choice. A premium waterproof puck speaker with balanced sound, a built in strap, and a long battery for travel. At 1.2 lbs (558 g) it weighs much less than the Sonos Play at 2.9 lbs (1.3 kg). It supports aptX Adaptive Bluetooth, which the Sonos Play lacks. It has an adjustable EQ, which the Sonos Play lacks.
The Sonos Play is the longer-running pick. 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 18 for the B&O Beosound A1 2nd gen. It keeps a wired aux input, which the B&O Beosound A1 2nd gen lacks. It plays in stereo from a single unit, unlike the B&O Beosound A1 2nd gen. 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 B&O Beosound A1 2nd gen. It is rated higher for sound quality, and the $96 saving on the Sonos Play is not enough to make up the difference.
