Query: Good while it worked

I purchased these headphones in October for my daughter to watch her dvd and play her nintendo ds without disturbing others while we travel. She used them a maximum of four times, after each use the headphones were stored. By April of the following year, she was complaining that the headphones had no sound. Indeed after jiggling the wire the sound came in and then left. I'm back to the drawing board looking for a kid-friendly headphone.
