Pros:The only pro was that I got my money back.

Cons:Headphones wouldn't charge, wouldn't work. Cord was too short.

The Bottom Line: These should have been easier to use. The headphones, though adjustable were too wide. They did not work as advertised, buy at your own risk.
Maybe ours were just faulty.


We bought these wireless headphones with the intention of being able to watch movies on our 55"Vizio during all hours of the night without disturbing any nearby neighbors at our apartment complex. It seemed like a good idea at the time...We bought these from Amazon.com in 2012, where we buy a lot of our stuff. We paid $71 for them at the time. I see now they're advertised for around $105 at the same site. Maybe they've fixed issues with them. Anyway,they arrived within the scheduled time frame and we got free shipping with them, saving $8

The headphones come with: Transmitter charging station,  AC Power adaptor,  Connecting cord,  Unimatch plug adaptor and Rechargeable Nickel-Metal Hydride Battery.

Technical Jargon: Headphone Type: Closed, supra-auralWireless Type: RF @ 900MHzDriver Unit: Dynamic 40mmFrequency Response: 10 - 20,000HzTransmitter Cord Length: 39 3/8 in. (1.0 m)Transmitter Weight: 7.7 oz. (220 grams), Headphone Weight: 10.59 oz. (300 grams).
 
Charging issues:
This item had decent consumer reviews across the board and in the end that's why we got them. As per the instructions we placed the Nickel-Metal Hydride Battery into the left ear cup and placed it on the charging transmitter to fully charge for a day or so before use. The charging port is very sensitive and takes forever to sit the headphones just right so it will begin charging. Both ear pads must match up PERFECTLY in the ports. The red light would come on to indicate it was charging, then it would go off a few seconds, indicating it wasn't sitting in the cradle correctly anymore. We would try to adjust it to no avail. We ended up placing a clothes peg on it, pegging both the outer and inner band loops together, then the red light came back on! Several hours later it would go off, but the green charge light never came on to let us know if it was charged or not.

 It was a pain just to try and start the charging process. This should be the easy part. If it actually charged when you put it in the cradle it might've been less of an issue.

Cord should be longer.
Another issue was that the connecting cord to the headphone port on the TV was too short. Unless the power outlet was by your favorite TV chair, then you were going to have a problem. We had to place our transmitter charging station BEHIND the TV at the nearest outlet. Sony do not recommend the transmitter be that close to the TV. Since the cord was only a few feet long you had to sit a couple of feet from the TV, fairly inconvenient, but that was just power outlet placement.

Headphones didn't work at all.
After that was done the cord went into the headphone jack as instructed, but the TV wouldn't mute. No sound came from the headphones at all, even with the volume control on the ear pad. We tried muting the TV, even turning the sound bar off, but...nothing. There was no sound from the earphones at all.
There are many many comments in this area on other sites and of how to fix these issues, but after all we tried I was pretty tired of dealing with it.

We now had a set of wireless headphones that just didn't work. We contacted Sony and Vizio about the issue but they had no idea what we were talking about and were of no help whatsoever. Vizio had us reconfigure our TV settings which actually screwed things up, and STILL there was no sound through the headphones.

Adjustment issues with headset.
By this stage I planned to return them, and I think for the best too. These headphones were adjustable but I couldn't seem to get a comfortable fit. They were too loose and I had to hold them on my ears so they wouldn't slip. Other people have reported the same problem.

For the people who it HAS worked for, a static 'hiss' issue:
Another issue people have reported was a low level 'hissing' static through the headphones that would annoy them. They fixed that problem by not using the volume control on the headphones much. Turn it to 1/4 volume, THEN adjust your TV volume until it's audible through the headphones, then the hissing disappears and the 'phones become clear.

The final say...
 
But then again, these are issues only when you can get them to work in the first place! We couldn't. We gave up. We returned them for a full refund and decided wireless was just too much trouble.

I have now bought a nice pair of http://www.amazon.com/Audio-Technica-ATH-M30-Professional-Closed-back-Headphones that I have reviewed WITH a long cord for half the price of the wireless Sony's, but I use it only for watching movies on my computer instead.

Maybe one day I will look into another more reliable wireless set for the TV but after the headaches that came with the Sony MDR-RF970RK Headphones it certainly won't be in the near future!
