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 Roam 2 ranks #94, rated 3.2/5, at $179, $216 cheaper, which does not close the gap in sound quality.
The B&O Beosound A1 2nd gen is the better-sounding, longer-running pick. A premium waterproof puck speaker with balanced sound, a built in strap, and a long battery for travel. It is rated for 18 hours of battery against 10 for the Sonos Roam 2. It is rated IP67 against IPX5 for the Sonos Roam 2. It supports aptX Adaptive Bluetooth, which the Sonos Roam 2 lacks.
The Sonos Roam 2 is the lighter option. A small Wi-Fi and Bluetooth speaker with water resistance, Alexa built in and Sonos multiroom support. At 0.9 lbs (429 g) it weighs noticeably less than the B&O Beosound A1 2nd gen at 1.2 lbs (558 g). Watch for: Exact same sound quality as the original Sonos Roam.
Buy the B&O Beosound A1 2nd gen. It is rated higher for sound quality, and saving $216 with the Sonos Roam 2 does not make up for the sound-quality gap.
