If you want closed-ear headphones, then check out the ATH-A500/A700.
AFAIK, the AudioTechnica ATH-A series > ATH-AD ones.
The Sennheiser HD280 Pro is ok for a closed can, except that when I was checking into it last year I came across a lot of reports saying the build quality had deteriorated to the point where the headbands were cracking easily. If you have access to warranty, it may not be too much of a worry.
