content: Contrary to the other reviews,I didn't have any problems with these headphones. I had them hooked up in a few minutes, it was very simple. The only thing to wait for is the batteries to charge. I walked around the house and outside without any problems and was outside before I had a little distortion, but nothing too major. I wear a size 7 and 3 quarters baseball hat and had no trouble with these fitting my huge head. They are adjustable to somebody much smaller and also much larger than myself. I do think this is a great product considering JVC website has them for 130 bucks and I bought them on Ebay for 18 bucks new in the box. I will be buying these for my friends and family for Christmas, an excellent product.
