Ugh.
So I enjoyed my HD600s for several years and then one day when I was cleaning the foam pads in front of the drivers .. they pretty much dissolved and tore into a million pieces of foam. So I instead just listened to them without the foam between my ear and the drivers. The problem is during that time I guess some hairs got through to the drivers and I started getting a crackling sound.
Fast forward to yesterday and the crackling was getting annoying. I opened up the headphones for the first time to remove the hairs/debris and when I snapped the driver assembly to remove it, one of the tiny wires connecting the voice coils to the connectors also snapped.
The wire that snapped is below in reference pic, the 'extremely thin filaments'
So now I'm without sound at all in that particular driver.
What would be the best solution here? Sennheiser wants ~$160 to repair it so that's out of the question.
Each new HD600 driver is ~$70 and each new HD650 driver is ~$50. I'm afraid if I just get one new driver it'll have an imbalanced sound since the other working driver is like six years old. And if I got two 650 drivers it'd save $40. But I've never heard them (HD650) and am unsure if I'd like them as much in the long run.
What would you guys do?
