 Great choice for wireless headphones September 21, 2007

I can't believe that I haven't found reviews for this product! I got a system so my wife could listen to the TV while watching in bed and not have the sound disturb others. I got this one because -1- it is RF as opposed to infrared so if she goes into another room she can still hear the sound, -2- has "drop-in" inductive charging of the rechargeable batteries as opposed to teeny-tiny contacts, -3- is from a well-known manufacturer as opposed to some off-brand, -4- it had switch-able frequencies to diminish the chance of interference with other 900MHz devices (I had to look at Sony's website for that), -5- the price is reasonable because of the quality reputation of Sony, and -6- it was available from [...] as opposed to some fly-by night company.
I was very pleased to find that it had arrived with the right cable (mini stereo to RCA L&R plugs) AND it works with devices that have RCA jacks OR mini stereo jacks because the transmitter has both types! We are fortunate that the TV has a headphone jack (unusual for the size of the tube) and it cuts off the TV speaker.
The sound in the headphones is amazing - so much better than sound from the speakers in any of the TVs in the house. I may get some of these instead of a surround-sound system for the family room.
 A piece of crap, don't waste your money October 13, 2007

To put it simple: don't buy this product. The sound quality is sub par and the reception is horrible. There is no bass what-so-ever. Even the free headphones that come with the iPod are better quality. On top of this, the volume is way too low, even on max. To make matters even worse, the reception is shabby, There are 3 preset channels, all of them equally as bad. All the time you will hear this constant static in the background. This is an issue with most wireless headsets (analog ones) but its really bad with this model. Even with the volume on max, the static sounds louder. Its really that bad.
The sound quality is just lackluster on all accounts. It seems like its running a high-pass filter on the soundwave because it simply destroys music. Especially with electronica, you will lose like half of the sounds (most importantly theres *no* bass). For watching movies it muddies everything with the static so voices are more difficult to understand. Even playing online games, these headphones are a disadvantage. The stereo sound is not that great. Audiophiles steer clear.
Just to re-iterate, this product is really a complete piece of crap, I've never reviewed a product so bad. I thought since it was a Sony, it would be better than the $20 RCA wireless headphones I've got, but they aren't. I still use them sometimes just for the convenience of wireless, but aside from that these headphones are just worthless. I know they look really cool, they are actually comfortable and have that fancy wireless charging battery, but if the sound quality blows, whats the point?
UPDATE: I found out that you need to plug these into a pre-amp or stereo receiver. They sound like crap if plugged directly into a source. If you have a good receiver then the problems mentioned above are greatly reduced. There is still some static, and the bass is a little shallow, but the sound quality and volume levels are much improved from before. Had I known this, I probably would have gave this product 3 stars.

The MDR-RF925RK headphones worked really well with my Ipod and another stereo I tried (better than I expected!) but they had trouble with the TASCAM 2488 digital recorder that I wanted to use them with. The recorder is an 24 track "digital studio" that I use for recording instruments (guitars mostly). I wanted the wireless connection so I could roam freely while playing and recording the guitars. But for some reason the headphones have a lot of noise when used in combination with the recorder. I may try the infrared type.

Having a hearing loss we had to keep the T V louder than normal. This solved the problem as the family can listen to the T V at normal level, and I can hear with the wireless headphones. And they are glad that I no longer ask, "what did they say?"
The reception quality is good, and walking to different rooms, I did not loose reception.
I hooked the transmitter to the T V using the extra audio jacket on the T V. This way the T V sound stays on. This was not in the hook up information instructions. If you hook the receiver to the phone jack, it disables the T V speakers.
A connecting cord (phone plug, stereo miniplug) comes with it. I bought an extra one. That way I plugged the connecting cord into the headset jack on the radio, and the other one into headset jack on the receiver of the headless phone. This way I can leave the transmitter (which holds the headset also) in one spot. If both the radio and TV are on at the same time, you can just disconnet one, otherwise when listening to only one, you just pick up the headset, and it turns on automatically, and you don't have to do anything.
For the price, it can't be beat.

These wireless headsets are great. Able to keep TV volume down so as not to bother others. Extremely good stereo sound.
