Query: WirelesHeadphones work Great

A friend of mine recommended these headphones -- After taking them out of the box and plugging them in (long enough to allow the battery to charge) - we started using them. Great sound! - Dual plug-in jack allows one to plug into the front headphone jack or rear audio out jack of the receiver. Seems to charge readily and easily -- No complaints!
