Hi Ian, It's quite likely to be one of those totally stupid design copyright issues. In short, if others were to do it, Sennheiser would claim it's an infringement of their design. Some idiot in their legal department might even be stupid enough to claim it's copyright.

One thing that's always impressed me is that they but a vertical line of 3 dots on one side of the head band to represent the Braille letter L. This means that you can correctly orientated the cans. This must be a very simple thing to do and I wonder why more manufacturers don't do it.
