High pitched Hiss or Buzz from Flex remote control

Both of my Flex remotes make a high pitched buzzing or hissing sound. I received a replacement and it does the exact same thing. I'm 41 years old and this noise is extremely loud and irritating. I think these remotes may have a serious defect. Disappointed because otherwise the remote works well. Would be amazing to have Xfinity acknowledge this is a real issue and commit to a redesign for the remote.
