Our overprotective parental genes have led us to express concerns about underwater electronics on more than a few occasions. It's that old radio-bathtub-electrocution warning from our childhood, not unlike the standard you'll-put-your-eye-out routine.
So even though it may not be scientifically necessary, we approve of the sealed-case design of this waterproof MP3 player from Japan's Sunconnection. The airtight casing has even skipped the usual display (gasp), though it seems to have most of the standard specs, Fareastgizmos says. And even if it does end up failing, you'll only be out $25--just hope that it doesn't happen while you're in the water with it.
