Headphones are an important peice of electronic. They can come in handy in all kind of situations. So to find the perfect ones when if you have an ipod, look for the genuine ipod ones, because they have alot of fake ones and make sure the back is not shinny, because if it is, then its fake. also look if its a 2.5 - 3.0 mm because if its not one of those, then its definatley fake.
