Short answer: the Bogasing G4. It ranks #27 of 175 medium speakers by sound quality (rated 4.0/5) at $38.29 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 1.8 lbs (0.83 kg) travel-friendly speaker with 50W output, IPX7 protection, USB-C charging, aux and microSD playback, LC3 Bluetooth and TWS 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 compact 2.2 lbs (1 kg) portable with IPX5 splash protection, aux input, LDAC/AAC support, Sony’s app, speakerphone capability, power-bank output, stereo pairing and Party Chain linking. 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.

The Two Speakers In Full
Bogasing G4: $38.29 Amazon $38.29 eBay
Pros: 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. Measured bass extension of 56Hz (-10dB).
Cons: 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.

Sony SRS-XB30: $199 Discontinued eBay
Newer model: the Sony ULT Field 3, ranked higher, rated 3.4/5, released Apr 2025. See every Sony XB and ULT generation.
Pros: A compact 1kg portable with IPX5 splash protection, aux input, LDAC/AAC support, Sony’s app, speakerphone capability, power-bank output, stereo pairing and Party Chain linking. It reaches a useful 95dB maximum level and has a claimed 24-hour battery life at moderate volume, making it a convenient older outdoor option. Measured bass extension of 55Hz (-10dB).
Cons: 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. Its micro-USB charging and older Bluetooth 4.2 platform now feel dated, so it is best considered for features and used-market value rather than sound quality. Discontinued.
