Summary: Died after 40 days
Review: After receiving the headphones and following the directions to charge 24 hours, they worked fine the first couple times they were used. Then I began noticing that the indicator light on the base showed the power on when they were not in use. Shortly after, the headphones started to die after a few minutes use and would not recharge even when left as long as 2 days undisturbed.

Sony instructed me to send them in for service. After many, many follow-up calls I was told that my headphones could not be repaired and I would be sent a replacement. After many, many more calls Sony informed me that there were no replacements available and none expected within the foreseeable future. Sony offered me a full refund of the purchase price, which I accepted.

After 3 months I am again looking for a set of wireless headphones. The Sennheiser RS-65 set looks good to me. While I applaud Sony for doing the right thing and issuing me a refund, I cannot recommend this Sony product.

Summary: Turn Up the Transmitter Volume
Review: I almost returned to seller. Went back and read the doc again. It says to turn up the volume to at least 5 or 6. After turning it up, no more problems with static.

Summary: Sweet Sound and Nice Style
Review: I bought these headphones so I wouldn't disrupt my room-mate and I love how they sound, and the quality of manufacture. The signal carrys really well over distances. And They are the most comfortable headphones I've ever worn. I would recommend these things.

Summary: Save your $$$...BEWARE, these headphones are pure junk!
Review: I give this product 1 Star because it's the lowest to select from...should be a -5 Stars rating...!!!

Bought a little more than 3 months ago. From the beginning lots of static making which was even worse when you were not stationary. The static has gotten continually worse and is now to the point these headphones are unusable. Sony referred me to an 3rd party authorized repair center about 30 minutes drive away from my location telling me it was the closest to me...hell, I live in the greater San Jose/San Francisco Bay Area (not exactly rural Montana, Alaska, etc.)...how is it possible that the "nearest authorized repair center" (which by the way is a private repair shop and not Sony directly) is a 30 minute drive away...!!!

TO ADD INSULT TO INJURY, they also informed me the warranty was 90 days labor and 1 year parts so I would have to make two 1 hour round trip drives to their repair center, show all of my proof of purchase documentation and PAY A LABOR CHARGE to get my 96 day old headphones that never worked properly in the first place and are now 6 days out of labor warrenty repaired.

Summary: So far so good
Review: I have had these about 1 week and so far I am pleased. I live in a subidivion house in the suburbs and the interference is not that bad. In the same room of my 2 level house, they pick up wonderfully and there is no static or interference anywhere (even if I am moving around). This has not been the case with many of the analog 900MHz/2.4GHz phones I have used in the past. They seem to have places with static even 2 feet from the transmitter but not with these headphones. However, the cordless phones do not seem to get worse with greater distance from the transmitter, but these headphones do get a little worse when you leave the room. As I walk through the rest of my house, there will be a few small spots where I will get some static, but almost all of the time is spent with no static at all. Sometimes there is no static, but volume just seems to go down slightly. I am not sure if this is a signal receiving problem or some other problem.

I was not surprised to find out that my 900MHz telephone interferes horribly with these headphones. When I get a call or turn on the telephone, the headphones are unusable. But even with the phone handset turned off, there must be some handshaking between the base because there was a click that would occur about 1 time per second in the headphones. I pulled the battery from the phone handset and it went away. So I either have to stop using that handset, or remember to put it in the metal filing cabinet before I listen to my headphones. My 2 other 2.4GHz phones do not cause any problems. Overall I am happy with these headphones.

Pros:

1) Really good sound
2) Auto on feature (come on when you put them on your head)
3) Better than expected reception.
4) Pretty comfortable, and despite there size, do not feel bulky
5) Very long NiMH battery life (24 hours)
6) I am listening to more music than ever!!

Cons

1) Need to keep 900MHz phones away (this might be a problem in an apartment where you can't control what kind of phone your neighbor uses)
2) Full battery charging takes 24 hours!! Apparently the charger is just a timer that cuts off in 24 hours. If you charge for 24 hours, take them off of the base and put them right back on, it would charge for another 24 hours.
3) You can get to the battery, but I don't think it is really meant to be replaceable. And I am sure it is an expensive battery pack (but I don't think it is meant to be replaceable because they do not tell you the replacement pack, they just tell you how to remove it before disposing of the headphones)
4) Fairly difficult to get back on the base so that they can charge.

I almost bought an infrared (IR) set of headphones because I mainly just needed wireless in my one room. Also, I heard IR headphones have almost no interference in the same room, but of course they do not work at all out of the room. But I have found that I enjoy walking around the house and still having the music playing.

BTW, I bought these headphones because I love music and listen to everything from classical guitar to doom metal and my wife doesn't like anything but pop music. So I think she is happier with my purchase than I am.
