Yea make an adapter like this (or buy one pre-made) one and you can plug your headphones into it:
Lots of X-100 Mini users plug their headphones in direct and are happy with the sound quality. Give it a try before you decide to modify it. If you do decide to add resistors ben_r_ used 220 ohm resistors and was very happy with the results.
Finally got the parts to make my version of the robinette box. It will feature 2x4 female banana (input/output), jack and xlr and a switch for attenuator/ no attenuator circuit. Do you think it will affect sq to use the attenuator circuit with he500 (assuming it is 12 dB preferred resistor network)? I have a little hiss with he500 and a tiny little bit with he-5le
Internal box it is.. Will use it with other amps in the future
I have to get a new neutrik jack as the locking mechanism doesn't work in the one I've got, though. Very annoying..

Just remove the locking mechanism. I have done it to several Neutrik locking jacks. Its just a red piece of plastic inside it.
davidsh, I have a pair of HE-500s that I used to test the Robinette Box with and as I said in the review I cannot detect a difference in sq when the resistor network is switched in and out (the volume has to be raised with the resistor network of course).
An assembly tip: Try to do as much soldering on the connectors as you can before mounting them in the box--especially putting the resistors on the network bypass switch. Pre-attach all the wires to the headphone jacks because it can get a little tight in there. Feel free to pm me with any questions and please write a review when you've got some listening time with it.

Very nice robrob. You should shrink that down, clean it up, make a few and sell em on your website and eBay.

Thanks Ben, I intentionally used a large box for the prototype to make it easier to assemble and troubleshoot but it's a labor intensive build and the parts cost is surprisingly high so I don't think I could sell many.
