Great Wireless Headphones Have owned Sony Wireless Headphones Model MDR-RF970R for several years and love them. Decided I needed another set for a TV in my office, so I got the newer version MDRRF985RK and they are perfect. I have difficulty hearing the TV and it is not the volume, but the clarity of the dialog. These wireless headphones are perfect. They block out other noise and make watching TV a pleasure again. I can go into another room and still hear the TV clearly. The set up is very simple. I have recommended these headphones to many of my friends who want to control the volume at which they listen to TV while others watching can tune the TV to a volume that is comfortable for them. I have never had a problem with static. It is great that the battery recharges as it sets in the transmitter cradle. Update. Now that I have used the headphones for a while I have to say that they…

Disappointed Two major problems with this headphone.1. Very small transmittance range. If I walk to a different room just 30 feet away from the TV, the sound in the headphone starts breaking.2. There is no access to the battery compartment. I contacted Sony customer service about this, and they confirmed that the batteries are not user replaceable. If I need to replace them, I have to send the headphone to the service technician. So their specs published on Sony official website is deceptive. It states that this headphone can use both Ni-MH and simple AAA batteries.I would not recommend this product to anybody unless you are going to use it next to the TV and dispose it in two years when your original batteries go bad.
