Rf Wireless Headphones

I get two of this product to wach TV. The two are intefering, hard to make them work at the same houshold. The other unexpcted problem, the charger. The sony battery run out before a longer movie finishes. It needs Sony specific battery, really can not use other batteries in the unit. The cahrger does not take any other than sony, - sony figured how notto take it. Very inconvinient. Sound qulity OK for a wireless. YOu can notice the difference with a ($80-)Sony wired headphone. The wired phones still better. You should not expect they are the same quity of sounds, that is OK. Buy Rf Wireless Headphones!
