The iPhone remote cord of my P5s wore out. I caught it on too many things walking around the city, basically. I emailed customer service, and they agreed to send one out to me ASAP, which was great. Great customer service! I just wanted to point out that if the headphones hadn't been under warranty, it appears that the replacement cord would have cost $50.68 or nearly 17% of the purchase price.
I'm a headphones newb (which is probably why I have the P5s in the first place), but doesn't that seem kind of exorbitant?
