Short answer: the Ultimate Ears Wonderboom for its floating IP67 shell, the Tribit Xsound Surf for the metal grille. The Wonderboom is IP67 rated and floats, but it is not stereo, has barely any bass and recessed treble. The Surf has a rugged rubberized frame with a metal grille, though its bass does not go as deep as others and it has strange midrange peaks.
Buy the Tribit Xsound Surf only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Earfun Uboom L instead.
