Apart from wondering what type of job you work in where it's practical to wear headphones for 6 hours.... :)

Did you buy a set since getting your originals from your friend? I haven't done any searches yet for lower prices, but are these worth the premium for this size driver? I don't have the chance to use headphones much - I'm usually blasting music in my car or over large speakers at home. If I had a wireless solution maybe I'd go 6 hours at work too.
