Some may call it a gimmick, but waterproof speakers are here to stay. It might've been a passing fad when the first few manufacturers, like Ultimate Ears (UE, for short) and JBL, first started releasing these water-tolerant audio devices a few years back, but now they're a staple of the market. But even in an increasingly crowded field, the UE Roll 2 manages to stick out. The latest IPX7-rated speaker from the manufacturer offers improved sound from the original on top of a reduced price tag ? the Roll 2 sells for just $99 (£80, about AU$100). While a muddy bass keeps it from becoming one of the best portable pieces of audio hardware out there, a solid waterproof coating, detailed mids and surprising range make it a definite contender for the crown.
