Mother-in-law sharing room with another woman who keeps her TV volume way up, couldn't hear her own TV. Now she can tune in and hear her channels without the competeing noise of her neighbor. Also bought a set for husband who has hearing loss, now the rest of the family can listen at normal volume. Also great for listening with the TV volume off when the kids are in bed. The head set is comfortable but I find the volume control wheel a little small for my fingers. Other than that, these are great.

Price: That's the best feature about this Sony Wireless Stereo Headphone System - MDRIF240RK.
Comfortable: Not really, after a short period of time this Headphone is quite uncomfortable.
Sound Quality: Good for watching TV, I would not recommend it for Music.
Easy To Use: I have to turn my TV up quite a bit and then turn the headphone way down in order to hear and not receive static.
Design: Only work when you are in a line of sight, and then only up to about 50'.
Difficult To Use: I usually have to turn on a light at night when I want to turn this off.
Other Info: I have about a dozen Sony products & I love them all. This one I only 'like'. If you are only willing to spend a very little amount of money on this and you are willing to except these limitation. then and only then could I recommend this item. Personally if I was to do it all over again I would purchase a more expensive headphone set.

Buy this and get what you pay for!!!

          Comments about Sony Wireless Stereo Headphone System:

          I bought these for my elderly mother so she can hear the TV without turning it up so loud it disturbs the rest of us. These are Infrared-based and my other Sennheiser headphones are Radio-based so I knew they wouldn't interfere - and they don't. One thing I like about the Sennheisers (which I use late at night, so not to wake others who are sleeping) is that I can get up and get a snack while still listening to my program. With the Sony's you can't do that - you MUST face the transmitter and you MUST be in visual contact with it. Well for mom, that's just fine and she's more than happy with the sound quality. We did figure out how to place the transmitter correctly so you wouldn't have to hold your head perfectly still to avoid hiss... still this is a real pain... but once we got it figured out they work fine. You can't beat the price.

                Comments about Sony Wireless Stereo Headphone System:

                I bought these so that I could watch TV in bed and not disturb my wife as she tries to sleep. For that purpose, they work just fine. The range is not that far, but my bed is only 15 feet from my TV, so it's not a problem. If I have them on and walk out of the room or go around the corner, they stop working. The only real issue I have is that you have to turn the TV volume way up so that the sound quality in the headphones improves...don't forget to turn it down before unplugging the base! Also, it would be nice if they could be left plugged in all the time, but the external TV sound cuts off when you plug them in, so you have to plug them in and unplug them when you're using/not using them. For the price, this was a very good buy and I'm overall happy with them.

                      Don't have to tune it in to get what your listening too. It's all set to go when u turn it on. Sound is terrific...like being at the show when watching TV. Have one in family room, 1 in two bedrooms. We can use our headphones to receive the signal in each of those 3 places....individualy or together. No more yelling about turning the volume down!!!!!!!
                      Chargeable battery doesn't work(no big deal) I used regular alkaline batteries and they work fine.
