You definitely want resistors in line to drop the output a bit. You may not need the resistors for the HD-800 headphones but I wouldn't try it on the other headphones.You also have the problem where you do not want to hook the two negative speaker outputs together. You want a resistor between the negative speaker output and the common negative hookup on the headphone. I believe most amplifiers would balk at shorting the negative speakers outputs together.
Single ended headphones have individual hot connections for the left and right sides but share a common negative hookup. You don't want to try hooking that to your speaker outputs. You may get away with that on some amps but I don't think you want to fry anything. Before you hook the grounds together make sure it won't damage anything.

So far I have seen very few that the individual outputs are balanced to ground. I happen to have one, and DIY amps with 0-4-16R output taps have grounded the 4R and used the secondary for some cathode fb. With SS amps, if you want to bridge them, you count on the negative already being tied together and connect only to the positives.
