Short answer: the Bogasing G4. It ranks #25 of 142 medium speakers by sound quality at $38.29; the Ultimate Ears Megaboom 4 ranks #137 and costs $200, which makes this an easy call rather than a real tradeoff.
What the Ultimate Ears Megaboom 4 offers: IP67 rated, floats, and finally uses USB-C charging. 20 hour battery life. ‘PartyUp’ feature syncs multiple UE speakers together. Watch for: A lot of distortion at higher volumes. Rolled off treble. Not very loud. They really screwed this up
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 Bogasing G4. It ranks higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so there is no real case for the other one.
Skip the Ultimate Ears Megaboom 4 if sound quality matters to you. It ranks near the bottom of the 142 medium speakers.
