Short answer: the Bogasing G4. It ranks #25 of 142 medium speakers by sound quality at $38.29; the Ultimate Ears Boom 4 ranks #91 and costs $109.99, so there is not much of a tradeoff to weigh.
What the Ultimate Ears Boom 4 offers: IP67 rated, floats, and finally charges via USB-C instead of the older Booms’ Micro-USB. 15 hour battery. Customizable EQ and speaker-pairing via the UE app. Watch for: Not much improvement over the old ones. Weak bass extension and thuddy bass. Gets distorted above 90%
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 Boom 4 and costs less, so the other one has nothing left to offer.
Battery life favors the Bogasing G4: rated for 24 hours against 15 hours for the Ultimate Ears Boom 4.
