Too much variable hiss and static

These headphones are horrible. I followed the directions exactly as indicated. I plugged it in and let it charge until the indicator went off (about 17 hours). I made sure no cables were crossed and the transmitter was in a good isolated location. It's all for not as the sound received by the headphones is inconsistently noisy depending on how subtle the sound is and how you hold your head.

These headphones are horrible. I followed the directions exactly as indicated. I plugged it in and let it charge until the indicator went off (about 17 hours). I made sure no cables were crossed and the transmitter was in a good isolated location. It's all for not as the sound received by the headphones is inconsistently noisy depending on how subtle the sound is and how you hold your head. And yes, I tried all three channels, the auto tuning button, moving the transmitter around -- everything suggested in the manual. These headphones just don't work well. The sound quality varies inconsistently, and I blame the active filtering built into the headphones. When no music or sound is playing, they are dead silent. Low frequency passes (rumbling, roars, bass drum, thumps, etc...) also contain no hiss. As soon as a high-frequency sound starts to play, the headphones are filled with a high-frequency hissing noise on top of the actual sound. Move around the room and the hiss will increase and decrease. Stand three feet from the transmitter, and the hiss will mostly be gone, until you turn your head and the hiss fades in and out depending on the angle of your head. These headphones are unusable. It's a shame -- for they're light and very comfortable to wear. The charging mechanism works great too. AND they ingeniously turn themselves on and off simply by wearing them or taking them off your head. But none of it matters for headphones are all about sound, and the sound quality coming out of these headphones is full of hissing and static. The more subtle the passages in the music, the louder the hiss is amplified. It's says Sony on the package, which is surprising. This is the first Sony product I've purchased (20+ years) that I've ever been unsatisfied with.

Expected better from Sony

By

from Medina, OH

Since it wouldn't charge I really can't say much good about it. We had an earlier model that worked fine. We just wanted the newer model that turned on automatically since husband only has one hand. Wish we could get one that would work.

$3 for the packaging

By

from Houston, TX

performance: 0 2 main problems. 1/ The other wireless network (radio, wifi, neighboors wifi, etc...) interfer and make scratchy weird noise. 2/ all the ABS parts make loud squeezing sound covering the movie you try to hear, each time a muscle of your face move a little bit. Design:0. It looks goods, but poor plastic conception make squeezing noise. Reliability:0. Tomorrow, it get back to the seller. Value;0. for 3 or 5 dollars, you can have a better sound, in a poor low price headphone

worst product ever

By

from Elyria, Oh

I purchased these for my father. We followed the directions exactly. The battery was supposed to be fully charged after @ 16 hrs. Twenty-one hours later it still wasn't charged. We were unable to get any sound at all. There are only a few options to try and none of them worked. I give this product one star and that's only because they look attractive.

Sony Quality

By

from Rochester, NY

Before buying I read the reviews and thought that all the negative ones were probably from people who just love to find fault. After buying these I tend to agree with them. 1. The headset is not adjustable for a better fit. 2. Very poor sound quality with virtually no bass 3. Static and interference with the transmitter less than 15' the headset 4. a squeal or squeak from the plastic connection between the earpiece and the headband whenever I move my head. All in all I am very disappointed in the overall quality of these headphones. I will say that this is the first poor quality Sony product that I have ever purchased in 30+ years as a consumer.

Questions about this item:

Robin P  ARE THESE NEW ? AND WILL THEY BE THE SOME MODEL YOU ARE SHOWING ? I'M AM LOOKING FOR THIS MODEL ONLY NOT THE NEW THE NEW MODEL
JOSEPH G  They do the job; but, sometimes I feel they are too big when I compare them with newer lighter weight, smaller models now available. Sound is good but if I change my head position I sometimes get terrible static or lose the sound entirely momentarily until I move my head back into the previous position. The self-charging feature is excellent, easy to use and handy, and for the size of them they are comfortable enough. And, SONY backs their product up very well. My original set had lots of static, but SONY replaced them and they work very well.
Shopper  can this headphone be used on a computer?
PAUL J  "Hello "A Shopper". These headphones will work on any audio output source. Your computer has a 3.5mm audio out plug and will accept the 3.5mm audio in from the Sony MDR-RF970RK base unit, just as a stereo or television. These are a good value for wireless headphones too! Good Luck. Regards"
