Listening to your iPod while cycling would be fine if it weren't for all those predatory motorists who drive like they're playing Grand Theft Auto. If you have your earbuds in while you're on your bike, there's a good chance a honk or yell might get lost amongst your tunes, so a lot of cyclists don't bother. The Slipstreamz earwear is made to let you better hear the sounds of your environment while still making your ride a musical experience. They're not earphones — instead they're hollow earcups that attach to your bicycle helmet and have cavities designed to hold earbuds (I'm guessing Apple's will probably fit perfectly) just a bit outside your ears. The idea is that by putting a little distance between your ear canal and the earphone, you'll be able to actually hear that semi truck in time to keep from becoming a pancake, even if you're rocking to the sounds of Korn at the time. Not only should the cups let you better hear ambient sounds, but they also reduce wind noise and wind chill, giving you hardcore winter cyclists a more comfortable ride. The Slipstreamz could also come in handy if you have weirdly shaped ears that prevent most earbuds from fitting securely. Which is a problem… uh, a friend of mine has. If you've been splitting your love between your passions for cycling and music, the Slipstreamz lets you have a threesome for just $14. — Peter Pachal
