My mod as posted earlier using a Rean connector would permit a 4 wires connection. I suggest it would be very worthwhile to practice soldering to build confidence. It’s not difficult !

I agree that you may want to try it yourself, but if you try desoldering a Beyer driver, get lots and lots of practice first. These drivers are famous for their fragility, and it's much easier to permanently ruin the voice coil wire than with most other headphones. I destroyed mine by holding my soldering iron on the contact for just 1 or 2 seconds too long. I've been soldering for over 20 years; it's a very easy, very expensive mistake.

I'm not saying not to try it, but be sure you make a little pile of practice projects before you risk a 70 or 80 dollar driver.
