Query: Waste of money

I purchased these headphones for my hubby. We charged the unit up as directed. It worked once for several minutes and died. Determined rechargeable battery that came with unit was dead/defective. Replaced with dry batteries as per the instructions. Unit worked a few times, but always taking several minutes for the sound to kick-in after the headphones were placed on the head (very annoying). It would be a better design if it had a dedicated on/off switch instead of using the extension of the inner headband to turn unit on/off. Finally stopped working altogether. Unplugged the damn thing and threw it in the closet. Note* If you buy one that works, you must remember to turn up the TV volume EXTREMELY loud once the headphones are plugged in, and remember to return it to normal volume before you unplug the unit!
