I bought these headphones a few months ago to run with. Hooked them up to the iPod Nano and they sounded great; loud, crisp and clear. For me they are also comfortable and stay in the ear while running perfectly. They also don't seem to 'tire' out my ear lobes or make them sore after a while. I have probably run with them about 60-90 times over the course of the past couple of months. Today, sadly, the left headphone started crackling and then one hundred feet later it died altogether. Looking to try to return them for a warranty exchange if I can. Maybe if you dont use them for serious working out they might last, but based on mine and others 'mileage' with them, your twenty dollars may be better spent elsewhere.
