Fwiw I heard the Sony x10 when they were doing the "launch parties" in the mall (really great idea, had dj, rave club lighting, and some banging ass speakers). I think they sound like utter trash. I personally wouldn't pay more than 50$ for those. The dj and the girl who was demo'ing the headphones said almost everyone passed on the headphones and inquired about the Sony speakers they were using (myself included and I'm not into speakers at all, but those were amazing)
@HBB, I'm surprised you have been blown off by customer service. I have been talking daily with a service rep for about 3 days lol. The time before this, I received almost instant responses to my e-mails.
mail address and name of rep you've been chatting with please.
We are having very VERY different experiences. Hok me up with the info via PM if you can :)
