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.
