I am posting here to 1) state that these RF headphones are fantastic, with great sound quality, and 2) to explain what one could try in case the sound through the headphones is noisy, or if you have sound in only one ear. So, I initially connected the headphones' red-black RCA jacks to the red-white RCA jacks of "Audio OUT" on the back of my (rather old) Vizio TV. The TV sound though the headphones was audible but had a lot of static, using the tuner (on headphones) and the channel button (on the sennheiser base) did not remove the static noise satisfactorily. This, turns out, is because the TV is old, i.e., the TV's RCA jacks are noisy/dusty/not making good contact, whatever. So I decided to connect the headphones directly to my Android box (I use an Android box delivering certain channels). The 1/8" (3.5mm) headphone socket included with the Sennheiser headphones fit into the AV (Analog video) jack at the back of the Android box, so I connected Sennheiser's red-black RCA jacks to Sennheiser's 1/8" (3.5mm) headphone socket which then went into the Android box's AV input (analog video input)). Now, the sound in the headphones could be tuned to be crystal clear, but the sound was only in one ear of the headphones. I figured this was because Sennheiser's 1/8" (3.5mm) headphone socket was not long enough to reach the stereo contact of my Android box's AV input. Anyways. I then realized the Android box did come with its own adapter AV cable (a cable with 3 jacks - one white, one red, and one yellow, the yellow is only for video). So, I now connected Sennheiser's red-black RCA jacks to the red-white jacks of my Android box's AV cable, and plugged the AV cable into the Android box AV input (analog video input). Finally! No static and crystal clear sound in both ears!

UPDATE. I wasn't ready to give up on these great headphones, so I did a little investigating. The power supply seemed fine, but the rechargeable batteries had given out. Once I replaced the batteries with new re-chargable ones they were back to working fine. I use Sanyo AA and AAA re-chargables around the house and had a couple handy, put in the new ones, charged over night and back to normal. All re-chargeable batteries have a life cycle, that's all it was. Easy to slightly twist the ear cap off (the side where the on/off switch is located) pop out the old AA's and put in some fresh and good to go. Don't use regular batteries thou . Some have complained about the volume and frequency dials being too close together on the right side, but it's not an "issue", it has to be somewhere and once you figured it out, it's not a problem. The little switch on the front of the charging unit is for changing frequencies, you have a choice of 3. I was getting some cell phone convo's on one position and switching to another position solved that problem. Although, its weird listening to someones phone calls and they don't know it. Kinda makes you think twice about who is listening to Your Call. After all, it's basically radio. works great, all around the house. I have it hooked up to the home office computer and use it when I want to rock out or it's late and don't want to disturb others. Also use to listen to podcasts, which I tried to listen to on youtube on the tv, but there is nothing more boring than listening to a podcast on tv. It's like listening to radio and staring at the radio. Hmm, guess people used to do just that. Maybe I'll get another set to hook up to the TV at some point. Sennheiser has been a top quality headphone forever and since I started using them as a DJ in the 70's. Glad they still have the great sound they are known for. My favorite "phones" have always been Sennheiser or Bose.

I struggle with hook-ups so I hope this helps you. I plugged in the stand (which is also the sound transmitter) and charged the earphones on it for two days. The transmitter has to be plugged into the audio of your TV. You have several choices. I used the adapter and plugged it into the rear of the TV and it worked. I had to adjust the volume and tune it, but that was easy. However, there was some kind of interference so the sound quality was barely tolerable (also that means another wire running to the TV). Having read other buyer letters, I then went to the cable box and found an audio out feed there. I didn't even need the adapter. (Happily, this eliminated the wire going to the TV!) Reception was better but still cut out annoyingly. Then I read that there is a tiny switch on the front, bottom edge of the earphone base/transmitter! I switched to the next channel. I tuned it again (easy) and it worked!!! It was clear as a bell! Love it. This means that the transmitter/ headphone charger stand can live near the cable box, my DVR and my DVD. The wire connections stay compact and no wires from this gadget go to the TV which is mounted up on the wall. I simply mute my TV, Turn on my earphones, adjust the sound on the earphone volume switch and enjoy.

My old faithful Sony wireless headsets went south during ur recent move into our house so I needed a hew wireless headset pronto. I've always liked Sennheiser so thought I'd give this one a chance, and for $60 I thought I could manage to live with it even if it didn't sound as good as the Sonys. WELL! It beat the Sony in every aspect. it's lighter weight, has fuller sound, a LOT more volume, farther coverage from the base, better overall sound though I do wish these wireless headphones had defeatable audio limiting on them. Otherwise, it's darn near perfect. I spent a lot more on those Sonys 5 years ago, but these more than met my expectations and hold a charge really well. They stay tuned to the transmitting frequency very nicely so you don't have to keep fiddling with the tuning knob. it helps that I live in a house so have no RF problems with other apartment dwellers on the same frequency, since there's enough separation between my house and the next one. I dare say that for $60 there's no better headphone I've ever found. My only real gripe is they have a tendency to fall off my bald head if I bend over for something or lean back unless I tighten them down a lot, which I don't like doing. if there was a way to stop that I'd love them even more. But I can walk around the house, listen to my favorite shows while I'm doing other things and getting some exercise, and no dropouts and no hiss. GREAT!

Ordered this on Saturday and received it bright and early this morning. This seems to be a excellent product. It feels solidly built even though it's mostly plastic, it doesn't feel cheap. The sound quality is very good. One concern I had was the ability to adjust both the TV and headphone volumes independently of each other. We had turned our TV's internal speakers off a long time ago and opted for a sound bar. The TV speakers are located in the back and sound horrible. We have the sound bar connect to the TV via an optical audio cable. So when the headphones arrived, we simply plugged them into the red/white RCA audio out ports on the back of the TV. Presto. I can listen to the TV with the volume set high on my headphones while my wife listens at a more moderate level via the sound bar. I watched an excellent review on these headphones on Youtube, which is what swung me to these. The headphones are pretty light so I don't see me having trouble wearing them for extended periods of time. I have to say I'm more than pleased with this purchase. I don't think you could do much better for a set of headphones at this price point. If you're considering this purchase I say pull the trigger and go for it. Update: 04/009/2017: I returned another wireless headphone set because I could not work out a few irks I had with them. Since I was completely satisfied with this headphone which I had already ordered once before for my TV, I decided to order another one for use with my computer monitor. At the time I ordered it, I never considered a problem with the fact both my TV and computer monitor (which is just a 32" TV but I'll refer to it as the monitor from here on) were both Vizo TV's. So the 2nd headphone arrives, and set it up with my monitor and at first everything is great. And then...... I'm surfing the web and me wife turns on the TV. Now I'm getting static. So I fiddle with the tuning wheel and get the sound for my video I was watching. I turn my head slightly and I start picking up the TV again. If I lean forward in my chair, I pick up the video, if I lean backwards I pick up the TV. I spend 2 days messing around with this problem, but could not come up with a solution. So I though, OK, let me swap out my monitor with my wife's which is actually a Sanyo TV. Problem persists. But then I notice something on the front of the charging dock which I completely didn't notice before. There is a tiny little, three position slider button on the bottom front of the dock. It occurs to me this must be a frequency selector. So I move the selector button to the second (middle) position, click a video from YouTube, and turn the adjustment wheel until I have a nice clear audio signal. Then I put on my TV headphones, turn the TV on and again turn the adjustment wheel until I have a nice clear audio signal. Then with the TV on, I put my monitor headphones on. Nice clear audio signal and no matter how I moved around I could not get a audio signal from the TV. So now my rating on this wireless headphone goes from excellent to perfect.

What was most helpful to me was another review explaining how to get these headphones working. He was correct, you only need to do this once. Our setup is a little different from plugging into a television so I wanted to share some slightly different instructions. We bought two of these. One plugs into a computer type, wired speaker headphone jack which is plugged into a television. The speakers are $20 Insignia. The other one we bought is plugged into our Yamaha sound system's headphone jack. But both installations were essentially the same. First, put in the batteries and put the headphones on the stand, the name Sennheiser facing backwards, which is also how you wear them, and the red light will come on showing the headphones are charging. Leave them alone for 24 hours, as the directions say. The red light never goes off when the headphones are charging or are totally charged. The next day, plug the charger into a power outlet and plug the 3.5mm audio plug in to the headphone jack of either your speaker or sound system. Our sound system took the bigger plug, which is in the package. This will work best if you turn the speaker sound or sound system sound way down and let the headphones control the sound. There are three channel positions on the bottom of the front of the unit. Our headphones are plugged in in rooms that are adjoining so one of us uses channel 1 and one uses channel 3 because we're watching different programs at the same time. But the directions are the same no matter what channel you use. Turn the headphones to the on position. Once you've put on the headphones, tune them by turning the dial until you get clear sound. You probably will have to turn up the sound on the headphone. Once they're tuned, you'll never have to retune them for your speaker or sound system again unless you accidentally rotate the tuning dial rather than the volume dial. I wish they weren't right next to each other, but it's something you get used to. These headphones are incredibly lightweight and can be easily sized. I have a fairly normal woman's head, which is generally too small for so many headphone sets. This one adjusts way down for an adult small head (not a child's) and way up for a larger head. They are extremely comfortable, far more so than the Brookstone ones we used for so many years. My husband uses them for hours at a time and they've never run down on him.

I was skeptical about the quality of mid-range priced wireless transmitter headphones. Have been using some cheap ones for 5+ years and was pretty used to the feedback that came with those headphones. After purchasing a 4K Tv recently (which I'm really pleased with...especially the up-scaling) the only downside was the headphone jack on this model would take over the audio output when the wireless headphones were plugged in. To solve this problem I ordered a digital-to-audio converter https://www.amazon.com/gp/product/B00NJCCAKY/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 which prevented me from having to plug in the 3.5mm input to the side of the TV at night, in the dark, every time I wanted to watch TV before bed. This solved that issue but just created another frequency that causes the buzzing/feedback in cheaper wireless headphones. When looking for a better high-end option I considered the Sony https://www.amazon.com/Sony-MDRRF985RK-Wireless-Headphone-Black/dp/B009A6CZYO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1480207207&sr=1-1&keywords=sony+wireless+headphones+for+tv but after looking further into those realized that they had a lithium-ion battery that can't be replaced once it goes bad. There were several other headphones I considered including Sennheiser's newest model the RS-175 https://www.amazon.com/Sennheiser-RS-175-Wireless-Headphone/dp/B00SLUI5SA/ref=sr_1_fkmr1_2?s=electronics&ie=UTF8&qid=1480207325&sr=1-2-fkmr1&keywords=seinheiser+wireless+headphones+for+tv that goes for $170 bucks among other options, but after doing some digging the RS120 has a second-generation iteration of the 120 II model for $99 and the one listed on Amazon is the 2009 model so I was skeptical. I ended up pulling the trigger and glad that I did. The Sennheiser is easy to set up, has incredible surround sound (the base is even great which I didn't expect) and there is literally no feedback from anywhere in our house. I would highly recommend this item for the quality but also the fact that I figured out I was spending ~$15 a year on replacing AAA batteries on the cheap one (this come with rechargeable batteries and charges by sitting them on the transmitter.) This would be a great X-mas gift for parents/grandparents who watch TV in the same bed at night and even younger gamers. I have no complaints and think would have bought this item several years earlier had I known how good they turned out to be!

There are great headphones if you live in an apartment, have others sleeping in the house, or otherwise can't have a large surround system. I like to be able to crank the volume sometimes late at night but don't want to disturb others and I've found these to be a nice solution. Obviously you're not going to get the same experience as a 7.1 surround, but I've always been pleased with the sound quality from Sennheiser products. The wireless factor is definitely nice too so that you're not tethered to anything. I've never seen any interference while using them, so it's easy enough to get up and walk to the kitchen or bedroom while still hearing the action. I like that the charger is integrated directly into the base and that the simple act of hanging the headphones back on the cradle pretty much guarantees a charge, since it's pretty hard to miss getting the charging plates to connect. I've also found that these are comfortable, even for wearing long-term, because they don't seem to so tight on the head as some others, which is especially nice since I wear glasses and some large headphones can be uncomfortable with those. Setup was a breeze and I've never had any issues with them not working clearly. The only minor complaint I have - and I don't know if this is a function of my setup or by design - is that if you pause what you're watching, the transmitter times out after a short time (I've never timed it, but just a few minutes) and I then get loud static through the headphones until I switch them off. I'd like it if I didn't get the static, but it's not a major issue.

This was a purchase for my husband who doesn't hear everything when there are other conversations or noises in the same room. We are very pleased these headphones have solved that problem. He can also listen and mute the tv if no one else is watching. Wish we had done this years ago!

Some customer said in an earlier review not to get caught wearing the headphones when the source goes silent. What happens is, as soon as the audio stops playing from the source [maybe in about 60 seconds], the base transmitter powers off. When that happens the headphones pick up loud white noise, but you can easily turn that down or turn the headset off. It is annoying, yes, but you can learn to anticipate it. There is no on or off button on the base transmitter, so it powers on when there is an input signal to it and powers off when there is no signal. so when your youtube video goes off, get ready for noise. the head phones work great for me, they are about the sound quality you would expect at this price range. and for anyone who cares, they are indeed RF, not bluetooth, so they wont be transmitting from your head, which is a big no-no for me. I sent back probably 6 or 7 bluetooth headsets because they were transmitting from the headset. I measured all of them with an electromagnetic detector meter and was seeing roughly 30 to 50 mW of radiation emanating from the headset. ALL OF THIS could be avoided if they don't include controls or voice audio input on the headset so that the headset has no need to transmit anything from your head to the connected Bluetooth device. but thats not what the public wants, they want devices which can transmit and receive signal
