There is a reason why the price is dropping like mad. That market is just far too competitive for the Amperior to be in and product that replaced it is a much better solution. Had mine for a month before I decided to get rid of them.
Yeah, I bought about 6 headphones during the black friday / xmas sales bonanza and the only one I returned were the Amperiors. Seeing all the hoopla every time they go on sale makes me want to buy them again to see what I missed. lol But seriously, I thought they were uncomfortable, first off. I thought they were also sibilant.
Still, glad they have lots of followers.
