Short answer: the Bose Soundlink Revolve+ II. It ranks #50 of 179 medium speakers by sound quality, rated 3.6/5, at $299. The Sonos Roam 2 ranks #94, rated 3.2/5, at $178, $121 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Bose Soundlink Revolve+ II is the better-sounding, longer-running option. A premium 360 degree speaker that sounds the same from any spot around it, with a carry handle and long battery life. It is rated for 17 hours of battery against 10 for the Sonos Roam 2. It keeps a wired aux input, which the Sonos Roam 2 lacks. The catch: Overly boosted bass, warm sounding.
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 much less than the Bose Soundlink Revolve+ II at 2 lbs (910 g). It supports AAC Bluetooth, which the Bose Soundlink Revolve+ II lacks. It has an adjustable EQ, which the Bose Soundlink Revolve+ II lacks. The tradeoff: Exact same sound quality as the original Sonos Roam.
Buy the Bose Soundlink Revolve+ II. It is rated higher for sound quality, and the $121 saving on the Sonos Roam 2 is not enough to make up the difference.
