Welcome

I decided to fix it myself, but I discovered that I had cut the small red wire (shown in the picture)

I went to the technician and he told me he couldn't fix it

Can I buy the driver from a specific store or site?

Anyone with experience or can help feel free

(Sorry for the bad language)
The red wire that triggered the piece

The second wire cut is yellow (fixing the yellow is very simple)

You can convert it to an HD580 Jubilee/HD600, just order the driver modules from Sennheiser. Probably. But you have to buy two or good luck matching the output and response.

Notes:
1. It'll become a 300ohm headphone, so unless you're using an OTL tube amp, chances are you're gonna end up getting half the power out of your amp into the HD580J/600 drivers. This is why you have to get a pair.
2. I say "probably" because Sennheiser is no longer managing their consumer electronics unit, and even before when they owned and ran it, they clamped down on sales of HE60 drivers to anyone with a verified serial number after someone purchased something like ten sets of all parts and assembled them into ten HE60s. So yeah...there are at least ten HE60s out there that you won't be able to get drivers for so don't just buy these willy nilly.
3. Also I say HD580J/HD600 conversion because I'm not sure they even stock Massdrop Edition headphones' drivers. Probably won't hurt to ask I guess.
