I just started a tech support job, the company provided me a headset made by Logitech model# ******. When I started using it I kept hitting the phone/call button thinking it was the mute button constantly ending my teams meetings or any other communication when I simply wanted to mute myself. So I created this! I had originally done a two piece design but didn't like having to glue it and that it couldn't pass over the filter. This one is able to pass right over the filter, but fits snugly onto the rectangular key buttons thingy. It works perfectly and is nice and snug on there still, and is kinda fun to play with while working. It's a pretty niche creation, but I hope it will help someone + it'll probably fit others!
