Helmet comms for coaching?

I use communicators with my boyfriend on track. We are both instructors for a NE track day org so we take a session or two a day to work together. It has been a total game changer for me. He tells me what to do and when to do it and then later why. And I trust him.....most of the time I find them to be extremely helpful. We also use them in the dirt as well. I personally recommend it, but it doesn't work for all.
