Short answer: the Skullcandy Terrain XT, though neither ranks well in its class. Both are rated 2.1/5 for sound quality (#170 and #173 of 179 medium speakers), and the Skullcandy Terrain XT costs $59.99 against $200 for the Ultimate Ears Megaboom 4, and with sound quality even, the cheaper one is the better buy. Both are rated below 3.0/5 among the 179 medium speakers, and the EarFun Uboom L, ranked #2 at $49.79, is a better place to start if sound quality matters.
The Skullcandy Terrain XT is the lighter pick. A waterproof speaker with a wrist wrap for carrying and pairing with other Skullcandy speakers. At 1.6 lbs (720 g) it weighs noticeably less than the Ultimate Ears Megaboom 4 at 2.4 lbs (1.1 kg). The catch: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
The Ultimate Ears Megaboom 4 is the longer-running option. 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 14 for the Skullcandy Terrain XT. It has an adjustable EQ, which the Skullcandy Terrain XT lacks. The catch: A lot of distortion at higher volumes.
Buy the Skullcandy Terrain XT. Both are rated the same for sound quality, and it costs $140.01 less than the Ultimate Ears Megaboom 4.
