My Earplug(s) Isn't Making Any Sound?
There is a wax guard on each Hush earplug speaker port that, if it gets moist, will not allow sound to pass through. The wax guards are the black stickers on the speaker ports. You can remove the sticker by peeling it off, and that should resolve the issue. The wax guard is not 100% necessary, so removing it should not be a problem.
If removing the wax guard did not resolve your problem, please reach out to us at email@example.com and we can assist you further!
