Swimming is a great workout—it uses most of your muscles and burns plenty of calories—but if there’s one thing we dislike about it (aside from kids in the pool—there, two things), it’s that we can’t listen to music while we’re at it. That’s why we tolerate all the peacocking jerks at the gym; at least we can listen to Van Halen while we hit the elliptical.
The Neptune Underwater Mp3 Player ($160) by FINIS might change all that. It holds four gigs of data, the speakers hook to your goggles, and—get this—it works by transmitting sound through your cheekbones and right to your inner ear. Honestly, it might be worth buying a set just to try that out.
