Look like the ones I remember at the drive in. 
I’m sure it sounds much better. Now the name blue tooth makes sense to me. It’s blue. 

I had a friend that was hard of hearing and could read lips. We would sit on a hill across from the drive in and he would tell me what they were saying. He ran into trouble when they showed a French X-rated movie. 

All we could understand was Fin at the end of the movie because I took French in 9th grade.
