I do like them quite a bit. I liked them enough at CanJam to give them a serious try, but the deal is that I have too many headphones. I'm already going to sell the 600s, and maybe the esw10s. My goal was always to have
One killer estat rig: O2
One killer dynamic rig: R10
One or two fun phones: the recently acquired HF2s and 225 cover that, and they're keepers
One killer portable: JH13
One gym phone: UE11
Though it feels really strange to kick out such a wonderful headphone, it's the only one I can see going. I think I secretly wished they could replace my R10s, and I could convince myself to sell them, but they don't. There's just no room for HD800s, and at $1400, I'd rather buy music or fund some adventure someplace. I'm going to give it one more week.
