Portable speakers with waterproof designs are more common than not these days, but for those with ultra-rugged lifestyles, speakers from Bose, JBL, and Beats might not be tough enough. It's louder than it looksThe Cub's greatest asset, like all Turtlebox speakers, is its extremely rugged design. I wouldn't recommend any of Turtlebox's speakers for critical listening, nor expect their look and sound profile to promote cozy, portable listening indoors. Turtlebox doesn't have a companion app, so there's no way to adjust the Cub (or any other Turtlebox speaker's) EQ or general settings. The Cub supports grouping with an unlimited number of other Turtlebox Cubs, Rangers, Grandes, and Originals (Gen 3) via Party Mode.
