I liked these pretty much. The sound is very tight, crisp and "at-your-face". These seem like "classic" monitoring headphones, as they provide very detailed sound and you can hear even the smallest nuances. Several downsides: bass is recessed, high-mids seems too strong sometimes, and I think they cause some ear fatigue. These aren't the most comfortable phones, but aren't too bad as well.

Nice semi opened cans, the sound signature was pretty similar to my closed HD200. The sound is good but the bass isn't tight enough for me. It's bloated, and it shows mainly on dance music. As you know, tight bass is one of my main concerns, so I abandoned these cans.
