I use Midland LXT600BB License Free radios with the basic earpieces. Other high school and college officials in my association also use them. They are a common radio in my area. EBO members have Arcshell radios that work well. I've used the stock Baofeng earpiece that had issues with static. Right now, I have Arcshell, Baofeng, and Midland earpieces. Midland seems to work very well.
