I wear in-ear headphones a lot, every day, probably 12 hours a day while I work, yard work, driving, while I walk the dog and while I sleep. I generally buy the cheapest earphones I can find because they end up really abused and only last a few months before the cord gets loose at the earphone or at the jack. Even if they last a little longer the cord will eventually get stiff from body oils and such. Not these headphones, I have been using them for 6 months at this point and they have 100% held up. I will be ordering more because nothing is indestructible.Another little nicety of these earphones is that the rubber cup that fits in your ear does not come off easily so in and out of pockets you don't lose the rubber cup. 

Question: How is the cord?
Answer: the cord gets loose
