Get an amp with a remote and use that to control the volume. Both Topping and Schiit have a few options like that. Also, Audeze engineers their higher end headphones to be able to play at extreme volumes for people with hearing damage. That's why they have little distortion even at 110 dB, they're meant to be used at a SPL of up to 130 dB! Anything LCD-2C or better, that is.
