Short answer: the Ultimate Ears Wonderboom 2, though neither ranks well in its class. It ranks #110 of 177 medium speakers by sound quality (rated 2.9/5) at $80 and is still sold new; the Xdobo X8 ranks #158 (rated 2.3/5) and is discontinued, so it is only an option used. Both are rated below 3.0/5 among the 177 medium speakers; for better sound, the EarFun Uboom L ranks #2 at $49.79.
The Ultimate Ears Wonderboom 2 is the better-sounding, lighter choice. A small waterproof speaker that floats and is light enough to toss in a bag for the pool or beach. At 0.9 lbs (420 g) it weighs much less than the Xdobo X8 at 1.9 lbs (860 g). It is rated IP67 against IPX5 for the Xdobo X8. The catch: Not stereo, barely any bass, recessed treble.
The Xdobo X8 is the deeper-bass choice. A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. Its bass reaches about 65Hz before falling 10dB, against 82Hz for the Ultimate Ears Wonderboom 2. It keeps a wired aux input, which the Ultimate Ears Wonderboom 2 lacks. It has an adjustable EQ, which the Ultimate Ears Wonderboom 2 lacks. The catch: The single full-range driver is the limitation.
Buy the Ultimate Ears Wonderboom 2. It is rated higher for sound quality, and the Xdobo X8 is discontinued, so it is only available used.
