Short answer: the Sony ULT Field 1. Both are rugged, but the Sony is IP67 rated and survives drops and 1m submersion, while the Tribit Xsound Surf settles for a rubberized frame and metal grille. Each has midrange problems: the Sony peaks in the upper midrange with rolled off treble, and the Tribit shows strange midrange peaks plus bass that does not go as deep as others.
Buy the Sony ULT Field 1. It is rated higher for sound quality and still sold new, while the Tribit Xsound Surf is discontinued.
