I purchased these to use with my TV however the static is so bad when the line of sight is 1 foot to 20 feet, that I cannot use them.

I purchased the Sony MDRRF960RF Wireless Headphones three weeks ago. After ten minutes of use, a loud popping occurs, as if a capaciter is shorting out. When I said loud popping, I mean loud popping. The power to the transmitter immediately goes out. Sony Service in Laredo, TX has had them for two weeks now and has done nothing to address my concerns. I’m sure I just got a “bad” set, but Sony Service could at least contact me and answer my questions as what they are going to do, and when.

-reading the literature,planning ahead, and noticing the odd square plastic adapter ends on the supplied aaa batteries, one is left with the impression that when the rechargeable batteries eventually fail one will need to get Sony BP HP550 batteries. The only link I found was in Europe and they looked to cost more than the headset pkg.!!
You can of course use alkaline aaa: but be sure NOT to put them in the charger!!!=
Now, it may be that any rechargeable battery will work-but it is not apparent in the literature, and I don’t know for sure.
I am especially sorry about this since I sent a pair to my brother in law after reading all the rave reviews!
Also, although headphone ear foam replacement is referred to in the nmanual, no part number or source is offered-as with the batteries…Give yourself a break: pick another brand.
In this day and age when it is hard enough to try to be GREEN, is SONY helping?

Maybe I just don’t understand this wireless system. My husband and I purchased these because he watches TV in bed. He is hard of hearing and turns the volume up to the point it keeps me awake.
But with this wireless headset we thought you would not have to hear the volume on the TV at all. Well that’s not true. It says turn the source of the volume up instead of the headset so there is no hissing. Well you can still hear the hissing and the TV volume is still turned up loud.
We adjusted the base and he is not far from it. He still has to have the volume on the TV turned up. I thought it was just him so I tried them and I had the same problem. TV had to be turned up loud and static was unbearable for my ears.
SO WHAT WAS THE POINT OF THE WIRELESS HEADSET IF I CAN STILL HEAR THE TV?

I returned the product to the retailer. There was excessive fuzz when turning the volume up. Example on a 1-10 volume scale, the fuzz noise was obvious at about 3-4 and got louder as the volume was turned up. The fuzz sound was excessive and distroyed the sound clairity. This is totally unaccetible for a $70 pair of headphones. I was about 2 feet away from the infrared transmitter with no obstructions so distance or user error was not an issue
