> noise cancelling degrades over time

Glad to know that I’m not the only one with this issue. I’m already on my third replacement pair, but the problem keeps coming back. In my case when it fails the noise cancelling amplifies low frequency noise.

I’ve came to the same hypothesis and wiped my second replacement pair down with alcohol every other day, the problem STILL eventually manifests.
