Quietcomfort QC 35 II - one earcup cutting in and out, intermittent static
The right cup of my QC 35 II has begun cutting in and out erratically. It seems to be rooted in the hardware, as this happens anytime I move my head at all.
This does not appear to be related to any software settings on the devices it's connected to. It happens both when connected to my phone and computer, and affects all audio - including the inbuilt lady's voice telling me what it's connected to.
This began happening yesterday. I've also had an issue for the last few months where a static sort of rustling noise will emerge from one - and only ever one - earcup erratically. There doesn't seem to be any pattern to when it happens, but it does go away if noise cancelling is disabled. Which, for a pair of noise cancelling headphones, is obviously not ideal.
Any assistance would be greatly appreciated. The headphones are up-to-date on firmware, and I've already run through the device reset process to no avail.
