When you want to completely zone out of the world, you can’t do much better than to throw on a pair of headphones, turn up the volume on the latest David Hasselhoff hit, sit back and relax. However, when riding on your bicycle, it is infinitely important to be aware of your surroundings, and this often includes both your sense of sight and your sense of hearing.

Slipstreamz solves this battle between jamming away to your tunes and actually being aware of the world, because it allows external noise to filter in without too much trouble, while keeping your earbuds close enough to help you bob your head. Looking like a pair of molded foam and polyester earmuffs, Slipstreamz attaches to your helmet’s straps and provide a small slot for your snazzy white earbuds.

Best of all, they’re actually pretty cheap. Slipstreamz are available through iWorld in the United Kingdom for £7.49 (about $14 USD). Oh, and of course, they’re marketing this at all your iPod-ers out there.
