Right Airpod makes funny noise when I talk to touch it.

So my right ear airpod seems to be sensitive to touch and possible vibration. When I put on a winter cap for instance, it jostles the ear piece a bit and I can hear a scratching or scuff for a slight moment. I can replicate this noise by tapping the outside of it as well. In addition, if I have them in my ears and am talking, certain pitches in my voice seem to mimic this problem.

Other than that, they seem to work fine, but it feel like there is something loose in there vibrating around under certain conditions. I'd like to get it replaced, but I wanted to see feedback first.

Thanks,

Dave
