I sent it off the day i received them.
I sent a message to the seller in regarding of the warranty and all. They were kind enough to tell me what i had to write and everything. I am really not sure if i was supposed to get something back from Audio Technica like some sort of confirmation or a "Welcome aboard letter" or something lol.
So yeah, i never received anything back from AT. i am not sure if i even did it correctly.
Anyways, it should expire in October from this year.
Sorry.
I should have mentioned i purchased them on Oct 14, 2010. A day before my birthday
The price back then was around 97 dollars. Every retailer or e-tailer was selling it around that price. it was a pretty nice bargain if you ask me. Right now i see that it went up 50 dollars more or so.
I can advise you to see and try to haggle with the seller. Luckily, proaudiomart may take off a few bucks so it really is worth a try.
I still remember back then there was a little commotion of head-fiers who could have swore that the old batch of m50s (pre-2010) had a slightly better sound signature than newer ones or something like that.
Anyways, they are like 115 or so in Amazon right now.
eBay may be riskier because of the sellers. As long as anyone purchases it from some authorized dealer it is okay.
I would, however, expect the worse if i order an m50 from a seller living in Taiwan, China, Singapore or Thailand.
