HUH??? 
2004-10-20
Reception is generally terrible. They seem to work only when they want to. It's a big waste of money.
Impossible to adjust headband 2004-06-26
There is no way to adjust the headband, allowing the headset to slide down and off your head. If you move around at all you have to hold the headset in place. Sound quality (because of background hiss) is mediocre.
Waste of $$!! 2004-05-19
Bought these for a Christmas present for my boyfriend - the first time he used them they worked great...second time all you could hear was the conversations coming from our neighbor's cellphone. I have not used them since then - they are collecting dust on my entertainment center and I don't know what to do with them. I live in the Rocky Mountains and don't have a lot of neighbors - and like I said, they worked the first time I used them but sounded awful each time after.
Buy at your own risk! I would return them if I could...
Overpriced and noisy 
2004-04-26
Too noisy to watch DVDs or listening to music, lot of static, mostly if you don't stand still like a statue. Very disappointing from Sony. Buy Koss, Sennheiser or Bose. Oh and the connection between the base and the headphones is crap.
Poor for dynamic range of sound 2004-01-30
These are great for the average listener who isn't going to move too far away from the television or stereo while using them.
However, I have a major problem with them: I listen to classical music ALOT and the volume constantly adjusts itself so if I get to some loud part in the music, like a cymbal crash or burst of horns, the volume clamps down making what should be a climax in the music I'm listening to sound not much louder than a whisper.
That's HORRIBLE and there is nothing that can be done about it. I don't understand.
DO NOT by these if you listen to alot of loud/soft music. This is also a problem when watching DVDs.

Can't get rid of the static... 2003-12-31
I got these as a Christmas gift. Just tried them out and they are horrible! Couldn't watch an hour long TV show without getting frustrated and just taking them off. Huge amounts of static even though you are close to the transmitter and sitting still. Should you turn your head side to side (never mind walk around the house) you immediately get static in and out. Could be that I live in the city in a house with lots of interference??? But I wouldn't take the chance, given that I agree with other reviewers, the controls are hard to use and the phones don't sit well in the charger.
Sony MDR_RF945RK wireless earphones 
2003-08-16
I just bought an MDR_RF945RK wireless earphone and this report is based on my experiences after using it for about a week. At short range, the sound quality is very similar to other Sony earphones with wires (I used a Sony MDR-600 for comparison) and I am generally pleased with its performance. Within a range of about 30 feet, the noise level is quite low, while the user is seated. If the user is walking around the room there are small "sip" noises probably due to multipath. When music is playing none of the noises are very noticeable. At ranges longer than 30 ft and in other rooms of the house an intermittent background hiss is experienced which can be minimized while seated by adjusting the channel or by moving the head to a favorable position. I like the charger system but sometimes a little wiggling is required to make proper contact with the charger contacts. I wear glasses and sometimes have trouble with earphone comfort but these earphones are comfortable and are suitable for hours of listening.
Very Disappointed 2003-08-11
I used these headphones for the first time last night. Without question I just wasted [$$$]. First, as noted in other reviews, the controls are very small and difficult to use. There is also quite a bit of hiss when using these. I was sitting 8 feet from the televion and the reception was very annoying. I had trouble enjoying the movie I was watching because the background hiss kept distracting me. I fiddled with the settings and could not get any better reception.
The base station is constructed out of cheap plastic with very little weight and balancing the headphones on the charger properly is not easy.
This is the second brand of wireless headphones I've owned for watching DVD movies and I highly recommend to any potential buyers to stay away. I wish I had better news.
OK, but has some serious usability issues 2003-08-01
Sound quality: Good - But, use with my Yamaha electronic drums is impossible, as the headphones contain circuitry, which constantly clamps the volume.
Volume controls: VERY poor. The volume control is very small and I often confuse it with the tuning knob.
Comfort: Ok. They are a bit heavy and lack good head adjustments.
Battery charger-base: VERY poor. Setting the headphones onto the base, battery charger is somewhat difficult and takes some fiddeling with, every time!
