Summary: It's OK, I was expecting more
Review: So I thought it would be a great item to be able to listen to music in my house and not disturbe my partner. Wrong. I have to stay within the area of the base and no walls can come between the base and I. Maybe they should say something about this when they advertise. I thought it would be just like my cell phone and I could move around the house freely.

Review: THIS ISN'T THE EXACT MODEL I HAD. Feel free to ignore my review. However, the only difference is that the transmitter was smaller. I did enjoy using these for awhile, they turned off if I wasn't wearing them and they were dead silent if I was out of range. The quality was actually pretty good, assuming the battery is was charged. They didn't seem to run out of juice for awhile either.

The headphones, however, were not that comfortable. They hurt my ears after about 30 mins. Also, my ear pads tore off after about 4 months of use. I got replacement earpieces and I used them for about another 4 months. One day I just grabbed the headphones to take them off and they broke. I guess I should've taken them off with two hands, but that plastic on top is pretty weak.

Summary: Near perfect upgrade of previous models
Review: We have been using Sony infrared headphones for years. This model is by far the best and simplest to use so far. The major improvements are:

1) As long as you place the headset back on the cradle when you are not using it, you can forget about changing batteries or recharging.

2) A switch on the cradle switches cleanly between 2 program sources, such as 2 TVs or a TV and a stereo.

3) It turns on automatically when you put it on your head, turns off when you take it off.

Looking at some of the reviews I have to point out the difference between infrared (I/R) and radio frequency (R/F) headphones. The Sony is I/R.

I/R works the same way as the common type of remote control. You have to be either in line of sight of the cradle or where the beam can reach you after 1 bounce from a wall. It is more suitable for watching TV rather than listening to stereo unless you are willing to limit yourself to one room.

R/F broadcasts like a radio and has the advantage of at least the potential for working around the house, but introduces the following problems:

1) Tuning to the exact frequency is required and it may need to be retuned as you move around.

2) Potential interference with other R/F sources such as wireless phones.

3) Making sure that the source is strong enough to give you a good signal to noise ratio. This is especially true if you are using them with a TV. This can usually be solved by just turning the TV's volume up.
