In 2002 I bought a pair of Sennheiser HD580s on closeout from NewEgg for $131. One of the best purchases I ever made. I wear these headphones probably about 4-6 hours a day and just sent them of to get repaired by Sennheiser for a flat $150. I'm getting a new office at work and need a set of headphone for there but unfortunately the HD580s have long been discontinued. Here are the things I love about my 580s that I'm looking for in another set of headphones.
1. Must be Over-ear design. I wear glasses and any other types of headphones I have issues with. I've got a big head so large ear cups are not a problem.
2. Must use some type of fabric/velour/felt for the ear cups. No vinyl/leather/faux-leather. I've tried headphones using those materials for the cups and always end up with a lot of sweat where the material is touching my skin.
3. Must be an Open design, not closed.
If I had to change one thing, I wish my HD580s had a detachable cable.
I will be using a headphone amp.
Both the Sennheiser HD600 and HD650 are on my list but I'm open to looking at others. Say $400 max but would love something $250 or less. Unfortunately I don't think I'll ever get a deal like my brand new HD580s for $131.
