We got these to communicate with my son on his walk to and from school. It's little less than half a mile. The school is 1 neighborhood street behind our house. There's 3 houses directly behind ours then an open field to the school. The sound quality is quite poor for this distance. I was very disappointed since there is not much interference between the two points. They are easy to use and small.
