Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality, rated 4.0/5, at $42.49; the Ultimate Ears Megaboom 4 ranks #171, rated 2.1/5, and costs $200, which makes this an easy call rather than a real tradeoff.
Why pick the Ultimate Ears Megaboom 4: A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. It links with other speakers (PartyUp up to 50 speakers), which the Bogasing G4 cannot. It has an adjustable EQ, which the Bogasing G4 lacks. The tradeoff: A lot of distortion at higher volumes.
The Bogasing G4 is the better-sounding, lighter option. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. At 1.8 lbs (830 g) it weighs noticeably less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. It plays in stereo from a single unit, unlike the Ultimate Ears Megaboom 4. 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 Bogasing G4. It is rated higher for sound quality than the Ultimate Ears Megaboom 4 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
