These headphones are crap! I got them when I bought my ipod and they only last 3 days. I got another set when I got my Iphone and these ones are working currently but the wires started breaking two weeks or so after I got them. If they get tangled, these ones are very hard to untangle. The sound is usually okay, but even before they broke, I noticed that they get a lot of static. They never even stay in anyones ears. They are too big and are hard so they are uncomfortable to wear for a while. I don't recommend them for people who are working out or moving around a lot while using them, and I don't recommend them for younger people. Sound Quality It sounds okay, even when I play music slightly loud, but there seems to be more static with these than with other headphones. Battery Life There is no battery? Durability Break way too easily, Ease of Use They are pretty simple to use, just a pain in the neck. Design The design is terrible. They don't fit ears well.
