Without a doubt, Finis's SwiMP3 (128MB, $250) is the most unusual MP3 player we've seen to date. While the company doesn't specialize in portable audio devices, its many years of experience making advanced training equipment for swimmers are well implemented in the SwiMP3. And although the player could use a few notable improvements, competitive and casual swimmers alike will certainly see the appeal of the device.
You wear the SwiMP3 in the water, and the player comes attached to Finis's Lane 4 goggles, though you may use your own. The main downfall of this design is that it places the controls, which consist of three buttons (on/off, next/volume up, and previous/volume down), on the back of the head. Because the keys are already stiff and difficult to press, our test swimmer had to remove the player and goggles every time she needed to adjust the volume or change songs. There's no LCD on the player, but this isn't an issue, considering its simplistic interface and minimalist features.
