They work quite satisfactorily. I use them to listen to DVDs and video tapes with my TV. But they have this one interesting behavior.
I'll be listening along easily when suddenly the volume decreases noticeably. I then adjust the channel dial a bit and all is well.
Can someone explain to me why these earphones do what I have described below when other wireless earphones do not? And also, why does the volume suddenly decrease and what was seen as the advantage in this design?
