I'm satisfied with my purchase. They are a bit staticy, but provide a good movie experience. The static is acceptable. If you plan on using these for music, look else-where. I bought these because I live in a condo and hate watching movies with the volume so low. These offered a solution. I have a great movie watching experience, and my neighbors can sleep at night. Wifi at 2.4ghz will cause crackling at times. BUT.... Any rf audio is gonna suffer from this. Not just Sony products. The biggest con is the Sony proprietary form-factor of the battery. Four stars from me.

Stay away from this one.I am a long-term customer of Abt's and I've been well-satisfied with all other products that I've bought from the store. Not this time.The sound from the wireless headphone is of a lower quality than the regular, low-cost wired headphones that I had been using. Until I bought these, I did not discover that the wireless headset occasionally emits a scratchy sound.Shortly after buying the headset, they stopped working altogether. When I called the store, I was told to bring them in and the store would replace them. I assumed that meant that they would be replaced that day. After driving some distance to the store, however, I was told that they would have to be sent to Sony. [...] On top of that, I am anticipating the same type scratchy sound. These weren't worth the money or the hassle.

Not bad with the price, but not durable

By 

from canada

Comments about Sony Wireless Radio Frequency Headphones:

I liked the charge design and the price, so I bought it a year ago. As a lot of people already mentioned the static problem, all I can say is that this is true.That is one of the reason that I am going to use bluetooth device. But the static was not as bad as other cheap ones. Now this headphone just stopped working all of sudden. So my experience with this headphone is that if the static and durable problem can be solved, this is a nice product.

      Nothing but Static

      By 

      from Texas

      Comments about Sony Wireless Radio Frequency Headphones:

      Permanent static regardless of what I do. I can hear sound but the static is still there. Even if the audio jack is not connected, the static is still there. Seems like it's an issue with the base.

      I'm Hearing Impaired

      By 

      from Bellmore, NY

      Comments about Sony Wireless Radio Frequency Headphones:

      Since my hearing is impaired, anything that helps me amplify sound so I can enjoy time with my family is a treasure. I still need to use closed captions on most movies and TV shows but it's treat to hear the voices and music along with it. It was always just disruptive noise to me before, even with hearing aids. I'm really grateful to be able to share watching movies and TV with my family again. Before I got this I was only able to watch on my computer because it has high end sound card,and I stream movies and TV shows. Being part of my family again is wonderful.

      Good performance for the money

      By 

      from Oceanside, CA

      Comments about Sony Wireless Radio Frequency Headphones:

      These wireless headphones do a pretty good job of sound quality and comfort. They work well in the immediate area of my living room. They are sensitive to radio frequency noise generators (TV, computer, playstation, etc) and seem to work best line of sight. The only problem I have found is the noise reduction system pumping during extreme low frequency playback (pipe organ 10-20 hz), which you would normally never encounter.

      Comments about Sony Wireless Radio Frequency Headphones:

      Sound quality for this unit is poor and the volume control fails to adjust to a reasonable sound level. The headset is oversize and can be obstructive when laying down.
