I've just finished making a balanced Y-Split to use both headphones at same time. It makes me avoid having to fiddle behind the headphone stands when I want to swap, and should be useful when I invite friends over. ;)
I've used different color XLR connectors for the two inputs, that match with the headphones' cables' connectors. That way, even if I find myself using 2 cables that look alike, I can still tell them apart in an instant. I've used all black for the HE-6 and silver/black for the HD800.
The wire is Toxic Cables silver/gold, but I think I will make another with copper for one half and silver/gold for the other once I decide which one I prefer with which.

I used mid-centric for the HE-500, although I'm sure it has great lows too. Nice to know the HD 700 isn't as bright as some people say.
In that case, yes, I've got all the bases covered. I actually haven't used the M100 since I got the HE500.
