Short answer: both are discontinued, so this only matters if you are buying used, though neither ranks well in its class. Used, the Sony SRS-XB30 is the better pick: it ranks #133 of 177 medium speakers by sound quality (rated 2.6/5), against #158 (rated 2.3/5) for the Xdobo X8. If you want one new, the Sony ULT Field 3 replaces the Sony SRS-XB30 and is rated 3.4/5 at $208. Both are rated below 3.0/5 among the 177 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
Why pick the Xdobo X8: A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. It charges over USB-C rather than Micro USB. The catch: The single full-range driver is the limitation.
The Sony SRS-XB30 is the better-sounding, deeper-bass pick. A splash resistant Sony speaker with LDAC, a power bank output, a long rated battery and Party Chain linking, now discontinued. Its bass reaches about 55Hz before falling 10dB, against 65Hz for the Xdobo X8. It is rated for 24 hours of battery against 15 for the Xdobo X8. It plays in stereo from a single unit, unlike the Xdobo X8. Watch for: 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 Sony SRS-XB30 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Sony ULT Field 3, which replaces the Sony SRS-XB30.
