Short answer: the EarFun Uboom L. It ranks #2 of 179 medium speakers by sound quality, rated 4.6/5, at $49.79; the Skullcandy Terrain ranks #169, rated 2.1/5, and costs $49.93, so there is little reason to consider the other one.
The EarFun Uboom L is the better-sounding pick. A great value medium speaker with clear, natural sound, waterproofing, and a Video Mode that keeps audio in sync with video. It supports AAC Bluetooth, which the Skullcandy Terrain lacks. It keeps a wired aux input, which the Skullcandy Terrain lacks. It has an adjustable EQ, which the Skullcandy Terrain lacks. The catch: It cannot produce real low-bass rumble or fill a large, noisy space, and the top end loses some detail.
The Skullcandy Terrain is the lighter choice. A waterproof speaker with a wrist wrap for carrying and pairing with other Skullcandy speakers. At 1 lbs (458 g) it weighs noticeably less than the EarFun Uboom L at 1.4 lbs (650 g). It links with other speakers (SKDY Multi-Link, up to 99 speakers), which the EarFun Uboom L cannot. Watch for: No bass, very rolled off treble.
Buy the EarFun Uboom L. It is rated higher for sound quality than the Skullcandy Terrain and costs less, so it is the default pick unless a specific strength of the other one matters more to you.
