Bought it from headphones.com two weeks ago, listened on it for about 10 hours maximum, but I still much prefer my other IEMs (64audio u12t and Sony IER-ZIR). I use my own cables and ear tips, so besides 10 hours burn-in, it's basically like-new. I can always return it to headphones.com to get full refund (minus return shipping), but I know some people are still waiting for it. I just want to get back what I paid, if it's not sold in a few days, I will return it.
