Short answer: the Ultimate Ears Megaboom 3. It ranks #107 of 177 medium speakers by sound quality (rated 3.0/5) at $191.99 and is still sold new; the Xdobo X8 ranks #158 (rated 2.3/5) and is discontinued, so it is only an option used.
The Ultimate Ears Megaboom 3 is the better-sounding, longer-running choice. A tough waterproof speaker that floats and shrugs off drops, with a long 20 hour battery for beach and pool days. It is rated for 20 hours of battery against 15 for the Xdobo X8. It is rated IPX7 against IPX5 for the Xdobo X8. Watch for: Not stereo, barely any bass.
What the Xdobo X8 does well: A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. It keeps a wired aux input, which the Ultimate Ears Megaboom 3 lacks. It charges over USB-C rather than Micro USB. The tradeoff: The single full-range driver is the limitation.
Buy the Ultimate Ears Megaboom 3. It is rated higher for sound quality, and the Xdobo X8 is discontinued, so it is only available used.
