I bought a child as a gift, the appearance bribed. As soon as I heard the sound of these headphones, I was very upset. Well, the child does not understand anything. Microphone fell off after 5 months of use. I had to stick it with duct tape. For convenience, 3+ Do not press, do not fly off, but a little hard. The sound is kept well, outside the headphones you can hardly hear what sounds in them (although no one turned them on loudly)
