My trusty Logitech G633 headphones have intermittent sound in on headphone, the culprit is the 3.5mm -- PC slider switch (it's a bit weird as it is only ever set to PC). I assume there is some dust or a contact issue. I can get thing working in both ears by fiddling with different pressures on the switch but was hoping for a permanent solution. I've tried to blast compressed air in, as well as a bit of CRC, both of which improved things a little but didn't fix completely and it slowly gets worse.

Any thoughts on quick and easy ways to fix? TIA (Sorry for the grotty image, I did try and make them clean

What you have tried is good however you would probally be better spending the money towards a new pair as opposed to trying to find the perfect silicone grease to spray in.

headphones are not easy to take apart and fix…

edit, you will have to continue to spray in the CRC… enjoy the mess/smell/getting it on your skin and hair

You can usually pull the earcup off and disassemble it from there with philips screwdriver…

I would do that and see what is wrong with the switch rather than keep dumping stuff in and not being able to check what is actually wrong.

G633 from memory is wired so if it is switching to aux you can try just using onboard soundcard? They aren’t as bad as they used to be.

Thanks Spartan, the switch affects 3.5mm aux and usb equally unfortunately, was going to see if there was another path before embarking on what will likely be a one way breakdown.

Silicone grease is non conductive so wouldn’t be suitable.

Just to close this out, was actually easy to access the where the switch contacts, gave it a little scrub and it seems to be back to normal.
