Lightweight stereo headphones

My daughter requires some light, comfortable headphones for listening to a stereo at home (not in ear or with neck band). Over the head type needed, with earcups with a gentle grip (she has problems in her head).
Frequency Response Range 5 (yes!) to 30,000, but 20-20,000 or thereabouts might do.
Weight ideally under 100g, but up to 130 OK.
Very good quality required - price is not a problem.
Any suggestions - I have done a lot of research, but someone with more knowledge could come up with something better!

Jill,

Koss Porta Pros ~ £35. Open, very light and the fit means I can wear it for as long as I like.

Have a look, I think you'll be pleased.
