      Bought two headphones for my wife and myself for viewing TV. We have problems hearing dialogue on some shows. These work great. They are comfortable to wear and we have not missed a word of dialogue when wearing them. Sound is so good that I also have hooked to stereo and can listen to music and not disturb anyone else.

      One concern I did have was over interference from other sources since I have wireless phones, internet and FM transmitter for listening to music throughout the house. There is no interference or noise and I can move throughout the house and not lose the signal.

      Purchased the RF985RK after damaging my RF970R and finding the RF970Rs were no longer available. Selected the RF985RK as a comparable replacement. Found it easy to set up and use except you must remember to manually turn off the headset after listening as it has a manual on/off switch, unlike the RF970R's automatic headband switch. Reception range is excellent and as advertised. Battery life is excellent, charges quickly (batteries are lithium ion rather nickel cadmium). However, I'm rating the sound quality only fair (heavy base, with mid and high ranges lacking). It is because of this that I have rated the RFR985RK only 3 Stars. Other than this, I found the RFG985RK easy to use once I had adjusted to its more base sound quality. Its affordably priced and a good buy for the money.

      Comments about Sony MDR-RF985RK Wireless Radio Frequency Headphone System:

      I often watch movies late at night -- read: early in the morning -- and do not want to disturb my neighbors. As I have a Sony Bravia TV, this system seemed to be the logical choice. The price is right and sound is fine, but falls a little short on the bass end. If you want true audiophile sound, look elsewhere.If your TV has only a single 3.5mm port, you will need a splitter for the headphone system if you are already connected to a sound system. Alternatively, the system can be fed through the sound system via an adapter.This system is an inexpensive way to see if wireless headphones will work for you.

          My wife has issues with white noise, making televion a bit of a challenge... These wireless headphones are easy to set up, and not only is the sound clear and static-free, but they are comfortable enough to be worn for hours. A great value.

            I like to watch "cops & robbers" TV shows. When there is a lot of shooting, etc, the noise bothers my wife who may be reading or preparing dinner. These ear phones were easy to install, plugged into the TVs audio out. Then you just have to mute the TV and turn on the earphones for clear sound that is better than the TVs speakers. Muting the TV mutes only the TV speakers and not the audio out.

                Great Product. I don't know how they do it, but B&H
                had them delivered the day after I placed the order.

                      These headphones are simple to use and install. The range and sound quality is comparable to other, more expensive, wireless headphones I've tried. Best of all, they have a very solid, well made feel to them that leaves me hopeful that they wont stop working after a year and a half as those other headphones did with dreary regularity.The only reason I couldn't rate them 5 stars is the need to hit the Auto Tuning button most times after turning them on and off. That gets annoying, and has caused me to take the headphones off every commercial break, instead of simply turning them off.

I called in to see if this product would work with my TV and the man I spoke with was knowledgeable, polite and got the job done in an expedited manner for no added charge! They came in a couple of days and work perfectly. My son is very happy. I will not hesitate to buy from B&H in the future.

                                  Comments about Sony MDR-RF985RK Wireless Radio Frequency Headphone System:

                                  I bought this RF wireless headset (to replace a similar IR unit) for watching TV when my wife prefers quiet. I find them quite comfortable, and the fidelity is good, with very low noise. I would not say they are terribly loud, but certainly adequate for my use. I sit less than 10 ft from the transmitter, and have had infrequent issues with signal loss that were fixed by reorienting the transmitter a bit. I would not say the headset is mechanically robust, but like most plastic appliances, they should last well if you don't abuse them. So far, the only problem I've had was one of my own creation. To reduce household parasitic power waste, I power the unit from a smart outlet box that turns off accessories when the TV is off. As a result, the heasdset only charges when on the cradle with the TV on. They charge 10X faster than they discharge in use so I have never had a problem with this setup. Once, I forgot to turn off the headset, so the battery ran flat on the cradle; my fault entirely. Given the price, I am satisfied with this unit.

                                      I tried 2 pairs of these before I finally gave up. There is constant clipping sound doesn't matter how close I get to the base station.

                                      Comments about Sony MDR-RF985RK Wireless Radio Frequency Headphone System:

                                      Very easys to set up and works right out of the box. The headset has 3 channels and my initial trial produced some static. But all I had to do was rotate through the channels until I found the static free one. The separate volume control for the headset is great.

                                      If there is one con it is that they headphones are quite large but as over the ear headphones they really provide privacy and little sound leakage.

                                          We're living in cramped quarters while we remodel so I got these so as to not bother my family when I get up and watch tv early. They work fantastically. very comfortable, great sound and incredible range. Very solidly built.Really a bargain.
