I don't know about you, but I run farther, more often, and more happily if I can blast some tunes while doing so, and get reams of dorky statistical data from my iPhone afterward. Finding some running pants with an iPhone pocket was tough enough, but what's been even harder is getting a pair of earbuds to stay put in my ears and not drive me crazy with whooshing sounds as the cable flops around and rubs against my shirt. The kind souls at Klingg must know what I mess I am, because they made this groovy little device that basically tapes the cable down to your shirt with magnets.
