I finally got to listen to these today at Guitar Center.
Val, you almost had me sold.
No point in going into great detail since it's been covered 100 times, but in short:
Bass and Mids were fantastic. The bass was more prominent than I'm used to, but it was done well. The treble, for me, just needed a little more bite. It was all there, but just...polite, as others have said. It worked well for some songs, but left me a little disappointed when there was some nasty crunching guitar, or even on acoustic guitar recordings where the sound just wasn't quite bright enough. Regardless, the overall sound was solid, and it certainly wasn't the reason I opted against them.
In the end I just couldn't get used to the shape of the pads and the lack of isolation. Even when I thought I had found the right seal, things just didn't feel quite right. The pain in my ears set in pretty quickly and with all the noise I was hearing I just can't see myself using these on an airplane or crowded train, bus, etc...
Real shame. I
wanted to get them...I really did.
