I purchased these for my nephew. However, after reading reviews about other walkie talkies, I decided to test them before giving them to him. Needless to say, he did not get them. No matter how loud you talked (or how close you were to the other person), you could barely hear the other person on the walkie talkies (with the volume full blast). I tested them in several different locations, and no difference. I do not recommend these. I could hear the other person talking into the walkie talkie from another room better than I could over them over the walkie talkie.
