Short answer: the Bogasing M5. It ranks #61 of 177 medium speakers by sound quality (rated 3.5/5) at $52.99 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 M5 is the better-sounding, lighter pick. A compact, backpack friendly speaker with very long battery life and USB-C charging at a budget price. 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 splash resistant Sony speaker with LDAC, a power bank output, a long rated battery and Party Chain linking, now discontinued. 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.
