Short answer: the Bogasing G4. It ranks #25 of 142 medium speakers by sound quality at $38.29; the Ultimate Ears Wonderboom 2 ranks #89 and costs $80, so there is little reason to consider the other one.
What the Ultimate Ears Wonderboom 2 offers: IP67 rated and floats. Compact and light enough to toss in a bag. Watch for: Not stereo, barely any bass, recessed treble. Slightly boosted 93hz upper bass Dip at 9khz. You can tell from the micro USB that they are just feeding you the same crap hardware over and over, this is inexcusable for a product released in 2019. Not technically a 360 speaker, only front and rear.
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 Wonderboom 2 and costs less, so there is no real case for the other one.
If battery life is a priority, the Bogasing G4 is rated for 24 hours versus 12 hours for the Ultimate Ears Wonderboom 2.
