Hi,
 
I was wondering if someone who owns the HD700 (or has studied one in detail) can advise me on how the headband design works please? I was specifically wondering if it uses the same sort of design as the much older HD600 and HD650 (wide, thin, strong black metal spring) or whether it uses the approach that I have seen in headphones such as the HD555 (which used a more flexible plastic composite type of band reinforcement - at least where the band expands and is visible)?
 
Thanks
