A:Answerits two sets (one orange set, one yellow set)...the part you keep is the walkie talkie part and the other part more like a receiver...think baby monitor...you have the walkie talkie part and they can wear the other piece on a lanyard around their neck...when they hear you talking to them they can press a button and just talk to you without having to hold anything else down...its very cook actually...I am a nervous mom and i like that i can now give my child the freedom he wants but not cut the cord completely :)
