I bought the head phones so i can watch tv late at night, But they suck and i was mad that got them until i hooked my sony walkman. It works well with my walkman only when i set in my chair, If i get up the sound goes away. I thought sony made great products but this one i could do without, A waste of money. Sorry sony it is a bad product. I guess i will only use them when im tired and hook up my mp3 player and cant move around, Looking for something else.
