Short answer: the B&O Beosound A1 2nd gen. It ranks #11 of 179 medium speakers by sound quality, rated 4.3/5, at $395. The Bose Soundlink Revolve+ II ranks #50, rated 3.6/5, 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 option. 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 Bose Soundlink Revolve+ II at 2 lbs (910 g). It is rated IP67 against IP55 for the Bose Soundlink Revolve+ II. It supports aptX Adaptive Bluetooth, which the Bose Soundlink Revolve+ II lacks.
What the Bose Soundlink Revolve+ II does well: A premium 360 degree speaker that sounds the same from any spot around it, with a carry handle and long battery life. It keeps a wired aux input, which the B&O Beosound A1 2nd gen lacks. The catch: Overly boosted bass, warm sounding.
Buy the B&O Beosound A1 2nd gen. It is rated higher for sound quality, and the $96 saving on the Bose Soundlink Revolve+ II is not enough to make up the difference.
