I was told by the guy from RDD to fill out the repair form without entering any payment info since they are under warranty. I have printed everything and I am ready to ship them tomorrow morning. PDF form in link below.
Which way you think will be cheaper...Priority Mail, UPS or FedEx?
I also mentioned "a similar case" so they'll know is not an isolated issue.
This is the email of the Beyerdynamic repair guy which I also emailed already: email@example.com
I saw that form but they replied to my email. I gave them my address and they're sending a UPS guy to come pick up the headphones from me. They said I'll definitely have them back before Christmas. Just gotta include the receipt. Also I think Priority might be the cheapest.
