A quick note on Skullcandy's warranty process.
I filled out their form, printed out the paperwork, stuck it all in a box, and sent it away. I had a tracking number for the package, so I was able to see when their received it a few days later. A little over a week after they received the package, I was curious what was going on and how long it would take for them to get back to me, so I searched around the internet for people's experiences. A lot of people complain that they never get any word back, they take a long time to process everything, they don't respond to email, and other complaints, but I did find a couple of people who said after they called the company, they received their reimbursement.
I sent Skullcandy an email, and a couple of days went by with no response. I decided to call them up, and it turns out those couple of people were right. After a couple of minutes on hold, I talked to somebody who looked up my info, and a few minutes later I had a coupon code in my email. The best part about it is they don't send you back what you sent them, they send you a coupon code for what your product is worth, so if you want, you can get something else.
So in summary, if you didn't actually read through my long post here, if you need to send something back to Skullcandy, remember this: It doesn't matter how long you've had it, it doesn't matter what happened to it, get tracking with your package so you can tell when they've got it, and call them up a couple of days after you know they have it, otherwise who knows if you'll ever hear back. As long as you remember that it's a pretty painless experience.
(Ok, so that wasn't a quick note, but I hope it was useful to somebody anyway)
I will say that replacing their headphones, when it's some weird defect, is so easy to trade in for a replacement and also a nice way to upgrade for up to 50% discount on your next replacement. Only thing is the hassle of replacing them.
