Get the fucking surgery and get this thing healed properly. I let my screwed up wrist go for 9-10 months before getting surgery while in law school and initially uninsured (the initial urgent care assessment failed to find any clear issues because they are too small to see on x-ray in the beginning) and I have lived with the consequences ever since. Over 20 years later, I recently had another surgery to try to cap the damage. Don't dawdle. Get it fixed.
Had the day off today so went out for ten-pin bowling with my wife, daughter, and a friend. It had been years since we'd played ten-pin and now our arms are bit sore and tired.
I was joking or failing at humor or something like that. You do not have man hands, small or otherwise.
Anyway, as far as I'm concerned that's DIY enough to qualify for kudos. I recognized the drivers, having broken at least two pairs of KSC75s and remembered Ari's suggestion. Now just build yourself a 1/8" extension cable and the bug will take hold and soon you will be building massively expensive, horribly inefficient headphone amplifiers!
