I couldn't be happier. I went through a few pairs looking for the elusive perfect headphone for me. I started with the Audio Technica M-50's. I liked them but the bass bleed into the mids and they got bogged down during fast/complex passages. I moved on to the Grado 325is. I liked them as well, but the sound wasn't as full as I ideally would like. Enter the Senn HD-600's. I also liked them but they were a little too bland for my taste.
Finally I arrived at the HE-400's. They have the big bass like the M-50's, but not bloated or slow. The speed and attack is there like the Grado's and a balanced sound like the HD-600's. Also, the detail retrieval and instrument separation is better on HE-400's than any of my previous phones. I find the sound stage to be the most wide/deep and most natural of any of the headphones I've listened to, as well. A lot of people say the HE-400 has a harsh treble, but I find it great. Coming from the Grado's, the treble is more refined but still has the bite I loved about the Grado's.
In the end, I sold all my other phones. The only slight complaint I could make is: Occasionally, I find a song where I wished the vocals were a little more up front. However, those songs are few and far between.
At some point, I might go with an XLR balanced cable if I can find a copper/silver hybrid that wouldn't further brighten the sound. Other than that, I haven't felt the need to upgrade. My wallet thanks the HE-400's for that.
