I used a Shure proffesional Head set mic for a number of years with very good results. Although at the time, they were all wired mics. the sound quality was very good. cable connects to XLR outlet on sound system. cable was a bit troublesom when moving around but as I used it for a One-Man-Band situation and was sitting down therefore the cable was not a problem. I installed a switch in the cable just at the belt clip to turn it off so as to avoid unwanted comments etc. going out unexpectedly. On the positive side you are always on the mic at a constant distance. Approximately 2 inches. Actually, I still have this set and could be persuaded to part with it at a very fair price.
