Short answer: the Bogasing G4. It ranks #27 of 177 medium speakers by sound quality (rated 4.0/5) at $42.49 and is still sold new; the Sony SRS-XB30 ranks #133 (rated 2.6/5) and is discontinued, so it is only an option used. The Sony SRS-XB30’s replacement, the Sony ULT Field 3, is rated 3.4/5 at $208.
The Bogasing G4 is the better-sounding, tougher pick. A light, affordable waterproof speaker with surprisingly strong bass for its size, solid loudness, long battery life and stereo pairing. It is rated IPX7 against IPX5 for the Sony SRS-XB30. It charges over USB-C rather than Micro USB. 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.
What the Sony SRS-XB30 does well: A splash resistant Sony speaker with LDAC, a power bank output, a long rated battery and Party Chain linking, now discontinued. It supports LDAC Bluetooth, which the Bogasing G4 lacks. It links with other speakers (Partychain up to 100 speakers), which the Bogasing G4 cannot. It has an adjustable EQ, which the Bogasing G4 lacks. The tradeoff: Independent lab listening rates music fidelity only fair: bass has impact but is boomy and lacks the deepest notes, while the midrange can sound hazy, muffled and grainy.
Buy the Bogasing G4. It is rated higher for sound quality; the Sony SRS-XB30 is no longer sold new.
