    I had this 970RK for 2-3 years and never have the problems as many complained in the 1-star group - noisy, poor sound quality, short battery life, etc. Each is just opposit to me in a positive way.

    I have been using it in a single family house (vs. apartment building) and I always connect it to the LINE OUT of a TV, not the earphone jack, so that I can just mute the TV while listening to the headphone.

    It works so well for me that I am going to buy a 2nd set of the same thing so that I can always have a one fully charged waiting there when the another I am using runs out of battery (That is why I am here today).

    Hope this helps to tell why the reviewers are so wide spliting here - they may use it in different ways or locations.

    I noticed alot of reviews saying that these headphones are noisy (probably hissing). That is true only if you don't use them properly. The trick is to not use the volume control on the headphones as much. First turn the volume on the headphones to about 1/4. Then turn the volume up on the TV or other device you have them hooked up until audible through the headphones. All the noise and hissing disappear. The headphones are crystal clear if you do this. Once you adjust the volume on the source then use the volume control on the headphones to fine tune. I love these headphones. Very comfortable and well worth the money IMO.

    I was a bit skeptical of the quality of this wireless headphone after reading some of the lukewarm reviews here. I also went to Crutchfield to download the owners manual (too bad Amazon doesn't offer this feature - it's very helpful).

    This was to be a gift for my soon-to-be 92 year old aunt. She has problems hearing certain frequency ranges and is missing out on much of the dialog on television.

    She has an older Sony TV set (circa 1998) without a headphone jack, so a Sennheiser (my 1st choice) headphone was out of contention. I needed something to plug into the line out RCA connectors on the back of her set. This Sony unit seemed to fit the bill. I decided to have it sent to my home first to ensure it would work and to look for any idiosyncrasies. To my delight, I found none. Not a single problem...well, getting the headset out of the plastic packaging was a bit tough !

    I followed the instructions for the setup (I have a Sony, but a newer model) - easily done, by the way. I allowed the headset to charge overnight. So far, so good. I removed the headset from the cradle and placed it on my head...Voila...sound! And not just any scratchy audio, but rich and crisp. The audio compression circuitry was working as advertised and the headphone audio adjust allowed me to turn up the volume to an uncomfortable level. Perfect for a 92 year old lady hard of hearing.

    So, I gave it the range test...kinda. I gingerly stepped out of the house and walked around...perhaps 50 to 75 feet away. Not a hiccup or a dropout. I had a good feeling about this.

    So, I packed it up to be sent off to California...and my dear old aunt. I used my yellow Hi-Liter to mark areas of interest and attention in the instructions (my auntie is a bit of a Luddite).

    There are so many unwarranted negative reviews online these days that one begins to lose faith. These headphones work as advertised, wireless range is good (certainly greater then "4 feet"), there's little or no noise issue when properly adjusted, and they're reasonably comfortable and lightweight. Fitting them in the sleek inductive charger is child's play, and they fully charge overnight. While frequency response, bass reproduction, and definition are fine, they're not outstanding, but these are after all relatively inexpensive wireless headphones designed for the convenience and privacy of casual users, not audiophiles.

    As many have stated, there are enough cases of 1-star or 2-star reviews that I was very skeptical buying this model (or even the Sennheiser RS120 system for that matter). But I bought based on the "new" reviews that are showing up stating exactly HOW to set this up with your TV to get the result you want. So I will describe my exact setup and experience - hopefully it will help you make your decision.

    I have a Sony KDL-55EX620 LED TV and on rear side, it has a single "line-out/headphone combined" 3.5mm port. There are options in the TV in the "Audio" section to select between the two use cases and it configures the port accordingly.
    I believe newer TVs don't have a RCA/line-out with separate RED/White anymore, but they have a optical/coaxial digital audio out and a combined (or only headphone out).

    The new sony headphone manual explains the configuration really well (how to use with Line-out, or headphone-out, or on a receiver how to use the 2nd-zone or REC-OUT mode). I will describe the case for my setup.

    I don't have a receiver. TV is in bedroom and we both want to be on headphones to reduce noise at night waking up the kids (sleeping in close-by rooms). I configured my TV to use the combined port as "line-out" port. I believe this makes the audio coming out of line-out at full strength, and the TV Remote volume controls do not impact this output level. This allows the Sony Wireless Transmitter to receive a high-power audio signal and transmit high quality signal to the headsets. The headset volume control is there to personalize your required volume, so wife is happy getting a very high quality audio in her headphone and can control volume as she likes it.
