Hello everyone!

The right driver of my Sennheiser HD650 is dead, it simple stopped working without any kind of noise.

The wire inside de driver seems intact and the spring that fits with the cable connector seems ok too, I've tried to get it more tight but it doesn't made any difference.

Anyone knows what could be causing the driver to not play any sound? I have some experience with DIY In ears, so in theory I could repair if possible and I knew what is causing this, but I don't wanna tear the driver apart to find out if not needed.

Unfortunately I can't just replace with a new one because spare parts aren't available in my country, and importing from another place will cost too much.

Any thoughts?

Its happens due to wire corrotion inside membrane. It can not be repair.

Is it possible to open the membrane and change the wire? I have plenty of litzwire that would probably work.

Quite easy to open membrane of hd650..Use destilled water + soap.. The problem is when you reinstall the membrane. 70% change of getting rub and buzz, a crackling noise on bass section around 63,80,120hz. Due too not precise in installing membrane (voice coil touching magnet)

Store in dry and controlled environtment. Store in camera cabinet with humidity controller would do.

Thanks! So, destilled water + soap to remove the membrane glue? How to glue it again when reinstalling? I'm really thinking about trying that, I've got nothing to lose since the driver don't produce any sound.

There's any type of tutorial for open a headphone membrane? even if it's other model I think it could help.
