Short answer: the Ultimate Ears Megaboom 4, if you are buying new, though neither ranks well in its class. The Xdobo X8 ranks higher than it (#158 vs #171 of 177 medium speakers, 2.3/5 vs 2.1/5) but is discontinued, so only consider it used; the Ultimate Ears Megaboom 4 is still sold new at $200. 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.
The Ultimate Ears Megaboom 4 is the longer-running, tougher choice. A tough waterproof speaker that floats, with USB-C charging, a long battery and PartyUp linking. It is rated for 20 hours of battery against 15 for the Xdobo X8. It is rated IP67 against IPX5 for the Xdobo X8. Watch for: A lot of distortion at higher volumes.
The Xdobo X8 is the lighter choice. A cheap splash resistant speaker that plays loud for background music outdoors, with aux and microSD playback. At 1.9 lbs (860 g) it weighs noticeably less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). It keeps a wired aux input, which the Ultimate Ears Megaboom 4 lacks. The tradeoff: The single full-range driver is the limitation.
Buy the Ultimate Ears Megaboom 4 if you want one new; the Xdobo X8 is discontinued, so only look for it used.
