I talked to my reseller today and they were very flexible, they gave me a full refund and I'll just have to send them back. Not sure what to do next tho, i truly loved theese headphones and everything about them but I don't know if I want to buy a third pair. If i do buy a third pair I'm going with a different reseller, mostly becuase they are cheeper there. What do you guys think? Is it a batch-error? Should i just go for another pair? I ordered a O2+Odac combo before this happend and they should arrive in a few days. I emailed beyerdynamic and talked to a guy, he told me that they never had encountered this problem, i asked him if my amp could be responsible for this but he didn't think it was possible.
But for other headphones, a friend of mine recommended Philips Fidelio X2 so i might just buy those. But right now i still want the T90's.
First world problems, am i right?
