Short answer: the Bogasing M5. It ranks #61 of 172 medium speakers by sound quality (rated 3.5/5) at $52.99 and is still sold new; the Sony SRS-XB30 ranks #130 (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 M5 is the better-sounding, lighter pick. Compact enough for a backpack side pocket at under 1.7 lbs (771 g). At 1.7 lbs (757 g) it weighs noticeably less than the Sony SRS-XB30 at 2.2 lbs (1 kg). It is rated IPX7 against IPX5 for the Sony SRS-XB30. It charges over USB-C rather than Micro USB. The catch: Front/rear driver configuration.
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 plays in stereo from a single unit, unlike the Bogasing M5. 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 M5. It is rated higher for sound quality, and the Sony SRS-XB30 is discontinued, so it is only available used.
