In short: too many
I really liked the HE-400, I sold them just to buy a new amp, would still be using them if I didn't need the extra cash.
A few things, the headband gets uncomfortable after a little while, and the stock cable is really stiff, but you are going to replace that anyway.
And it seems to require mods to get the best sound.

I just bought a pair of velour pads, that was enough for me.
