Report "I put fresh batteries in and the headphones didn't work for very long. I thought I had left them on. I changed the batteries and they didn't work. I changed them 4 times and sill they don't work. The headphones arn't that old. Any advice? The bottom f the part that plugs into the TV says Sennheiser TR110. The headphones say HDR 110, so I'm not exactly sure what product I have, but I need help fixing it. I hope that helps"
