Short answer: the B&O Beosound A1 3rd gen for better sound quality, the Bogasing M5 for the lower price. The B&O Beosound A1 3rd gen ranks #19 of 177 medium speakers, rated 4.1/5, at $399. The Bogasing M5 ranks #61, rated 3.5/5, at $52.99, $346.01 cheaper.
The B&O Beosound A1 3rd gen is the better-sounding, lighter pick. A premium waterproof puck speaker with good sound, a long battery, and a battery you can swap, built to last. At 1.2 lbs (558 g) it weighs noticeably less than the Bogasing M5 at 1.7 lbs (757 g). Watch for: Distorts easier than the 2nd gen with deeper bass.
