Yes, a dual entry re-cable with something good like Mogami. Why re-cable?
"1. Simpler signal path. Mini XLR + headband + multiple internal solders and bits of cable all bypassed.
2. Better than stock cable.
3. Balanced operation.

Labor 3 hours, free (dressing the microphone cable is time consuming and it's been a long time since I last soldered anything. I also made an adapter cable so I can use the cans single ended if I wish). I actually had a lot of fun doing this, while listening to my speaker stereo system
Result. I was considering an upgrade to more expensive cans like Beyerdynamic T1s before I did this mod but now not so much. I am not saying that modded Q701s are as good as T1s. I never heard T1s. I am just delighted with the way the Q701s sound.
What would I say to those who say that re cabling has little or no benefit? I would say the are probably right, if they are just talking about sticking another cable into the mini XLR. I would also say that they have never heard a properly modded pair of X701 cans. I challenge anyone who has heard a stock pair of X701 cans and a pair that has been modded for dual entry, direct to driver operation to say that there is not much gain.
Would I say that this mod was worth $38 and 3 hours of work? YES!"
