Short answer: the Ultimate Ears Wonderboom 4, if you are buying new, though neither ranks well in its class. The Ultimate Ears Wonderboom ranks higher than the Ultimate Ears Megaboom 4 (#112 vs #170 of 175 medium speakers) but is discontinued; its replacement, the Ultimate Ears Wonderboom 4, is rated 2.9/5 at $74.50 and is still sold new. Both are rated below 3.0/5 among the 175 medium speakers, so if sound quality matters, consider the EarFun Uboom L instead, ranked #2 at $49.79.
The Ultimate Ears Wonderboom is the better-sounding, lighter choice. IP67 rated and floats. At 0.9 lbs (425 g) it weighs much less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). The catch: Not stereo, barely any bass, recessed treble.
The Ultimate Ears Megaboom 4 is the longer-running pick. IP67 rated, floats, and finally uses USB-C charging. It is rated for 20 hours of battery against 10 for the Ultimate Ears Wonderboom. It links with other speakers (PartyUp up to 50 speakers), which the Ultimate Ears Wonderboom cannot. It has an adjustable EQ, which the Ultimate Ears Wonderboom lacks. Watch for: A lot of distortion at higher volumes.
Buy the Ultimate Ears Wonderboom 4, the replacement for the discontinued Ultimate Ears Wonderboom; it is rated higher for sound quality than the Ultimate Ears Megaboom 4.
