Regular people like us (we're assuming you're a lot like us, ear-wise) have asymmetric ears, so anasymmetric bud like Asym (pronounced Ay-Sim) fits like nobody's business (an idiom, meaning great). Its flush fit and wrapped cable position (the cable runs over the top of your ear, man) means you can run on the treadmill (what are you runningfrom?) or do your Flashdance dance (without water of course...they're not waterproof), and they'll stay put. Asym also fits perfectly under beanies and helmets (for those doing the really sketchy stuff).
