A while ago you saw the totally immersible SwiMP3 here, and as a still-avid swimmer, I’m always on the lookout for improved tools I can use while in the water to help my workout. uCan is a new waterproof MP3 product that has a smoother, more elegant profile than the SwiMP3. Instead of using bone-conducting technology to deliver tunes, these rely on traditional in-ear earphones and comfortably rests on the back of your neck. It also packs in 1 Gb of memory and floats, two big things the SwiMP3 needs to improve to compete in the underwater music market. uCan begins shipping in July from Europe.
