Backontrack
I flew VC10's in the RAF and the service issued headsets were at best S**t and at worst s**t. Since flying civil multi pistons I looked at the Dave Clarks but thought they were a bit on the expensive side so I settled for the Sennheiser HME 100 and they set me back £160. They fold up into a tiny space and the sound quality and noise attenuation to my wind thrashed ears is superb - and they come with a natty flight bag. Personally I think sound attenuation is probably more important than sound quality. Good luck.
