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!!!

Great sound, March 2013

By MACisco

from San Francisco, CA

Comments about Sony Wireless Stereo Headphone System:

These headphones have exceptional sound. They're extremely clear, have amazing bass of all things and really deliver a quality sound experience. They are large and sort of require that you are sitting up or with your head facing forward. For instance, if you're being lazy in bed, you can't really adjust comfortably to lying on your side to watch tv with one ear on a pillow. It would be ideal if the headphones could twist to allow for that minor listening experience. Overall, they deliver, plain and simple.

    Proper set up

    By Kahn2007

    from Ohio

    Comments about Sony Wireless Stereo Headphone System:

    These do exactly what I wanted., a way to watch TV late at night when I get home from work without disturbing the household. I had hissing until I figured out how to set them up. Plug them into the earphone jack. This turns off the TV speakers and just leaves the headphones on. Turn the headset volume down and turn the tv volume up loud to 65 or so. Remember the TV speakers are off now. Then adjust the headphone volume to your comfort level. No hissing. If you leave the tv at normal volume setting and try to turn up the headphone volume you will get hissing.

          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.
