I'm sorry about the trouble you are having.
Unfortunately, because of numerous problems we have had with "gray market" goods, we can only honor warranties for customers who purchase directly from authorized dealers. This policy is outlined in detail here, which is in the footer of all our web pages.
We are not purposely out to make our customers unhappy - it is actually quite the contrary. By encouraging people to only buy from authorized dealers, we are able to ensure the quality of our products and the quality of our service. We simply cannot offer the same level of service for people who purchase goods that may have been altered, cloned, stolen or damaged. This is why we require a receipt of purchase.
I hope you can appreciate our position. If there is anything I can do for you, please do not hesitate to email me directly. I'll help as much as I can (with the help of our engineers) to see if we can do something with the headphones you have.
