Short answer: the B&O Beosound A1 2nd gen if sound quality matters most, the Xiaomi Sound Outdoor if price matters most. The B&O Beosound A1 2nd gen ranks #11 of 177 medium speakers, rated 4.3/5, at $395. The Xiaomi Sound Outdoor ranks #46, rated 3.7/5, at $49.99, $345.01 cheaper.
What the Xiaomi Sound Outdoor does well: An affordable waterproof outdoor speaker with a separate tweeter, decent battery life and linking to many more speakers. The catch: Bass reach is limited for the cabinet size, with a rated lower limit of 60Hz, and the boosted bass gets somewhat uncontrolled at high levels.
The B&O Beosound A1 2nd gen is the better-sounding, longer-running choice. 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 12 for the Xiaomi Sound Outdoor. It has an adjustable EQ, which the Xiaomi Sound Outdoor lacks.
Buy the Xiaomi Sound Outdoor when the price outweighs sound quality for you, and the B&O Beosound A1 2nd gen when sound quality outweighs the price instead.
