As GSA I would. It came in handy whenever I needed to have a conversation with the LOD/AP that was at all "sensitive". I also found that it was a lot easier to understand what people are saying when it's right in your ear.
I tried to use it when I transitioned over to backroom, but I found that it would come unclipped from my shirt when pulling CAFs or moving around casepacks so I quickly abandoned it. Also, it meant that I couldn't have one earbud in and still pay attention to my surroundings. 🙄
