Standard headphones, like the ones that come with your iPhone, work fine — they’re just not great for exercising. They aren’t sweat-proof, they have sensitive components (microphone, speaker, accelerometer) that are vulnerable to perspiration, and they’re prone to dying prematurely.
Sport headphones add a new dimension to your workout. They are light, have a comfortable and secure fit, and can handle the buckets of salty perspiration your dome dishes out. So whether you’re lifting weights, running or doing a total body workout, it’s time to swap out your basic buds for something better.
