Short answer: the Bogasing G4. It ranks #27 of 179 medium speakers by sound quality, rated 4.0/5, at $42.49; the Oontz Angle 3 Ultra ranks #163, rated 2.2/5, at $39.99. Close enough in price that the sound-quality gap is the deciding factor.
The Bogasing G4 is the better-sounding, deeper-bass option. 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 90Hz for the Oontz Angle 3 Ultra. 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.
The Oontz Angle 3 Ultra is the lighter option. A cheap, very light waterproof speaker with a long battery and plenty of features for the money. At 0.9 lbs (400 g) it weighs much less than the Bogasing G4 at 1.8 lbs (830 g). It has an adjustable EQ, which the Bogasing G4 lacks. The catch: Very little bass with horrible upper bass thud at higher levels.
Buy the Bogasing G4. It is rated higher for sound quality, and the $2.50 you would save on the Oontz Angle 3 Ultra does not close the gap.
