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 Boom 3 ranks #113, rated 2.9/5, and costs $132.99, so there is not much of a tradeoff to weigh.
The Ultimate Ears Boom 3 is the lighter option. A rugged waterproof speaker that floats, with a fabric shell, a stable Bluetooth connection and PartyUp linking for many speakers. At 1.3 lbs (608 g) it weighs noticeably less than the Bogasing G4 at 1.8 lbs (830 g). 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: Not stereo, barely any bass, recessed treble.
The Bogasing G4 is the better-sounding, deeper-bass pick. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. Its bass reaches about 56Hz before falling 10dB, against 91Hz for the Ultimate Ears Boom 3. It is rated for 24 hours of battery against 15 for the Ultimate Ears Boom 3. It keeps a wired aux input, which the Ultimate Ears Boom 3 lacks. 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.
Buy the Bogasing G4. It is rated higher for sound quality than the Ultimate Ears Boom 3 and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
