These are not made anymore…

Wire isn’t broken but the insulation is all cracked.

How would you guys recommend a repair of the insulation on this?

Probably just a couple of careful wraps using electrical tape.

Sennheiser is very good about having spare parts and repair parts. Have you contacted them for the cost/availability of a replacement?

I should have * repairing without electrical tape. Looking for a higher quality repair.

Almost anything else is a cut the wires repair, because you can't get heat shrink or other repair parts on.
There is "liquid" tape -- https://www.homedepot.com/p/Gardner-Bender-Black-Liquid-Electrical-Tape-4-oz-LTB-400/100119178 that wouldn't require cutting.

You may be able to open the plastic part and solder a donor USB cable.
