Short answer: the B&O Beosound A1 3rd gen for better sound quality, the Bogasing G4 for the lower price. The B&O Beosound A1 3rd gen ranks #19 of 172 medium speakers, rated 4.1/5, at $399. The Bogasing G4 ranks #27, rated 4.0/5, at $38.29, $360.71 cheaper.
The B&O Beosound A1 3rd gen is the lighter option. Longer battery than the 2nd gen (~24 hours at sensible volumes). 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 catch: Distorts easier than the 2nd gen with deeper bass.
Why pick the Bogasing G4: A 1.8 lbs (0.83 kg) travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. It keeps a wired aux input, which the B&O Beosound A1 3rd gen lacks. It plays in stereo from a single unit, unlike the B&O Beosound A1 3rd gen. The catch: 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 3rd gen if sound quality matters more than the price. Buy the Bogasing G4 if the price matters more than sound quality.
