Short answer: the Bogasing G4. It ranks #25 of 142 medium speakers by sound quality at $38.29; the Sonos Roam 2 ranks #74 and costs $179, so there is little reason to consider the other one.
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.
What the Sonos Roam 2 offers: Very neutral. Additional button for pairing instead of being shared with power button Watch for: Exact same sound quality as the original Roam. Bass extension isn’t very good. Not stereo. Gets distorted as you turn up the bass.
Buy the Bogasing G4. It ranks higher for sound quality than the Sonos Roam 2 and costs less, so there is no real case for the other one.
Battery life favors the Bogasing G4: rated for 24 hours against 10 hours for the Sonos Roam 2.
