I didn't finalize anything, I know a lot of people wouldn't even bother contacting HiFiMAN and try to resolve the issue, it's a double edged sword as obviously a lot of time has been wasted and it'll be another two weeks before I can get any other headphones, if they give the all go I'll just sell them as HE-6s to me are useless, otherwise I'll see about getting the HE-300s again or even the 400s if they give me compensation! I've heard head-direct are fairly bad as far as customer interaction goes though so that's unlikely.
I'm just not willing to send them back from my own pocket as I can't see a reason why I should lose money because of a mistake on their end, they're not exactly light and sending them to the other side of the world costs money I don't have.
I don't feel I have to justify myself though, most people would probably just keep them and I'm not out to win any karma points I just wouldn't get much sleep knowing I've close to stolen headphones (not really stolen but you get the idea). If they let me keep them I'll sell'em and will have replacements in a week or so and the extra money would probably pay off quite a bit of my student debt, if not atleast I can say I had HE-6s for a few days.
