I have excellent headphones Sennheiser 417 (since discontinued) but they are heavy and the ear pads are not cupped so they slide off frequently requiring help from my busy aide to readjust them.

Here are my design considerations:

Fairly flat response between 20Hz - 20kHz
Lightweight
Cupped ear pads
9' (3m) straight cord (not coiled) Could be longer. Don't prefer to add extension. 1/8" mini stereo plug (straight, not right angle)
Price range: =/~ $50-75

I realize I could go to Amazon and be overwhelmed with options that's why I seek your opinions.

Thanks,

Don
