Short answer: the Tribit Xsound Surf for a rugged build at a lower price. Its rubberized frame and metal grille make it the tougher pick and it costs $103 less, though its bass doesn’t go as deep as others and it has strange midrange peaks. The Sony SRS-XB20 is IPX5 rated with a pill shape that slides easily into a bag, but it sounds thin at higher volumes.
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.
