Questionable Product

We bought this for my father for Christmas. He needs to blast the TV to hear it and makes the rest of us go deaf ;)
We bought it at Circuit City for a great price. But when we plugged it in, after charging, the green power light never came on. So we charged for 2 more days, checking every couple of hours to see if it would work. Finally, we switched to regular batteries, and voila, green power light, but.... no reception. So I went back to Circuit City and exchanged them for another one (I figured maybe it was a bad set, we should try another.) I got home plugged it in and charged it over night...NO green light. I unplugged the power cord, plugged it back in and finally got the green light. Still had no reception. When I put the headset back on the charger, and lifted them off, there was no green light. When I unplugged the power cord again and plugged it back in I got the green light....Ummm, loose power cord? I could hear it change channels every time I hit the button but I never was able to pick up sound from the TV. I even walked around the house to make sure I was not too close or too far away. So I gave up and returned them. Now I am thinking about a Sennheiser.
