Short answer: the B&O Beosound A1 2nd gen on measured sound quality, the Bogasing G4 on price. The B&O Beosound A1 2nd gen ranks #11 of 177 medium speakers, rated 4.3/5, at $395. The Bogasing G4 ranks #27, rated 4.0/5, at $42.49, $352.51 cheaper.
The B&O Beosound A1 2nd gen is the lighter pick. 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 noticeably less than the Bogasing G4 at 1.8 lbs (830 g). It supports aptX Adaptive Bluetooth, which the Bogasing G4 lacks. It has an adjustable EQ, which the Bogasing G4 lacks.
The Bogasing G4 is the louder, longer-running option. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. Alan Ross Reviews measured it at 100dB at full volume, against 93dB for the B&O Beosound A1 2nd gen. It is rated for 24 hours of battery against 18 for the B&O Beosound A1 2nd gen. It keeps a wired aux input, which the B&O Beosound A1 2nd gen lacks. Watch for: The upper treble is boosted and uneven, while the mids sit slightly behind the bass and highs, so it is not a neutral choice for vocal-focused music.
Buy the B&O Beosound A1 2nd gen if sound quality is the priority over the price, or the Bogasing G4 if the price is the priority over sound quality.
