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 #10 of 142 medium speakers at $395. The Bogasing G4 ranks #25 at $38.29, $356.71 cheaper.
What the B&O Beosound A1 2nd gen offers: B&O Beosound A1 2nd gen uses 3.5mm aluminium driver + 0.75 inch silk dome tweeter. Its 558 g, claimed 18 hours (Manufacturer specified) battery life, IP67 protection, up to 93dB and mono playback make it a practical option for its intended room or portable use. Watch for: Bass is limited by its 58Hz specification.
What the Bogasing G4 offers: A 0.83kg travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS pairing. It reaches a useful 100dB maximum level and has a measured 56Hz -10dB bass point, giving it more low-end presence than many speakers of this size. 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. It has no app or user EQ, and its Super Bass and Vocal modes offer little practical differentiation according to listening tests.
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.
