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 and is still sold new; the Sonos Roam ranks #95 (rated 3.1/5) and is discontinued, so it is only an option used. The Sonos Roam’s replacement, the Sonos Roam 2, is rated 3.2/5 at $179.
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. It is rated IP67 against IPX5 for the Sonos Roam. It supports aptX Adaptive Bluetooth, which the Sonos Roam lacks.
The Sonos Roam is the lighter pick. A small, waterproof Wi-Fi and Bluetooth speaker with wireless charging, voice control 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: Bass extension isn’t very good.
Buy the B&O Beosound A1 2nd gen. It is rated higher for sound quality and still sold new, while the Sonos Roam is discontinued.
