RS 120 II

I am having difficulty tuning both left and right headphones in!

Assuming you are using an audio decoder converter between your tv and your Sennheiser I suggest you test the converter outputs individually. You may find one is not actually working (they should both work individually and give you stereo when both are connected. If one is not working you will need a new converter. Or you may find either left or right is not working well - perhaps one ear clear the other with sound but also static. I tried 2 converters as my first was quite cheap and did not work well. This was fixed by very gently readjusting the position of the plug (gently/slowly turn the connector and be ready to stop as soon as it hits the perfect spot). If you yourself are hearing impaired it might also help to have someone else in the family do the "tuning" as I've also found that the connector is very sensitive (sort of like tuning in a radio where you can hit the station but with a lot of static and have to marginally adjust to get the station without static). I turn it for my mother as she has trouble getting the precise point. And my biggest tip is that when you have set it never move the connectors or cords! Even the slightest bump seems to knock the connection enough to effect the sound. I am not sure how to include a utube link in this site but utube has some quite useful videos on optical connections for soundbars to android tvs, the principal is exactly the same and that's how I figured out how to fix it. Good luck.

Inserting the yellow power cord seems to be very stiff. The top light only shows for approx 1 minute. Should I force the power cable on a bit further ?

Can only suggest you give the two contacts on headset a clean with something that's not overly abrasive and do the same on the arms of the charging stand. Other than that ???

RS 120 II

The Sennheiser RS120 ll is connected OK but does not transmit the channel currently playing on the TV. For instance, I may be watching a broadcast on Channel 92 but the RS 120 ll is transmitting Channel 7!! Am I plugged in to the wrong socket? I am connected via a digital/analog converter using a coaxial cable. The TV is not a "smart" and does not seem to have a coaxial connection facility. Please advise.

Hi Ian, Not sure if I have experienced the same as you but I remember accidentally being connected to a neighbours base station and was listening to their tennis game when I had a football game on my TV. I suggest you check that your back station is powered on, connected and tinker with the tuning dial on your headphones until it syncs with your base station. If you have an neighbour with a similar unit try changing the channel on the base station as you could be using the same channel as them. Change the channel by moving the slider switch on the front of the base station and then re-adjust the tuning dial on your headphones until is syncs-up. Hope this works for you as it did for me.

Don't connect to the headphones port on your TV. This will cut out all the sound from the TV speakers. Instead, use the red & white cables and connect to the RCA ports at the back of the TV to the Sennheiser transmitter. In this way, others watching the same TV can hear the sound and adjust the desired volume (it shouldn't affect your headphones volume). You can adjust your own volume on the headphones.

My headphones lose the signal after about 5 mins. when I'm watching a replay through a recorder. As soon as I lose signal I switch to the TV and signal returns. What is the issue & how do I fix? This has only started to happen recently, have been using the headphones for a number of years without problem.

RS 120 II

I really hate the fact that these cut to very very loud static if no audio is being used for 2 minutes. Sometimes at work I need to pause my music for a second and focus on something, but I always have this nagging anticipation now that I either need to switch the headphones off or do what I need to do within the frightening time limit before the loud static attacks my eardrums. Is there still no fix for this?

...unless somebody designs a highly sophisticated integrated circuit and offers it for sale to be added to the inner electronics of the headset, which would check e.g. for 1 min. silence and then cuts off the battery supply from the headset and reactivates it again, when signal-flow continues, I do not see a fix for this...

PS: Also read my answer to puddy below: The static white noise actually has a purpose in fault-finding:
If you do not hear what you want, but at least white noise, you know that the issue is that these is no input signal being received by the sender...

They claim it's a feature / FCC compliance thing. They have to shut down the transmitter. My complaint is that the receiver doesn't detect loss of signal and mute, it continues to blast static a max volume.

I really wish I'd returned them for a refund, since I find I hate using them. I'll just fear the next blast of loud static.

You can compensate somewhat by making sure your PC volume is maxed, and only adjust volume with the headphones. That way they won't tend to be at such high volumes. But it's so incredibly annoying, and I'm amazed they're still selling the garbage.

How do you connect the Australian mains unit with yellow end to the base ? The video tutorial does not cover this and the quick guide isn't helpful. I've attempted to insert it into the base but get no power

RS 120 II

I have had my RF 120 II headphones for about 1.5 years and they've been great. But a few months ago I began experiencing a low background noise. It's not really a problem when I hear music, but when I'm watching movies or do other things without constant sound it's quite annoying. It does not seem to be due to the sound source (my computer) or the batteries in the head phones, but I suspect that it is the transmitter itself that's the problem. I have tried going through the channels on the transmitter, but that doesn't solve it. Any ideas what I can do? Thanks

Hi ‘Mads’, I also got a slight ‘background noise’ the other day, what I did is play around with the ‘TUNE’ sliding knob and fine-tuned that channel into the transmitter or you can change to another channel on the transmitter. I’m running my transmitter channel in the middle setting and once I fine turned it with the ‘TUNE’ turn knob it went away. You could also try to unplug the transmitter and replug it back into the mains and replace the batteries with new ones. Also, check all your connections to your TV set or wherever you have the transmitter pugged into. If that doesn’t work then you must have some sort of interference in the FM signal that is generated by your and around your environment (that wasn’t there before) check that also. If all that fails then, I would get the transmitter serviced as your unit is faulty. Hope this helps.

Just to be sure:
Changing the channel on the transmitter is one thing... - but you did not mention, if you fine-tuned the channel on the wheel below volume wheel on your headset...
Cheers, Peter K.

Yes, I have tried to fine-tune the channels. I do that every time I change the channel on the transmitter, but also every time I start using the headphones, so I'm sure to have the best possible sound. But the fine-tuning doesn't solve it.

With my Sennheiser RS 120 II's I'll be playing a game with very low noises were you rely on hearing peoples footsteps. I go a long time only hearing wind and birds waiting and after waiting a few minuets loud static fills my headset and I'm forced to tab out and make noise or make a noise in the game giving away my position how can I prevent this static?

Not familiar with your game but I can only suggest that the game itself at the point where you get the static, must issue sound in a format that your RS 120 headphones can't handle i.e. in other than Stereo format. Maybe the static is Dolby Digital (perhaps music) sound from the game. Check to see what sound formats the game uses. It also could depend on how your RS120 transmitter is connected to your sound output device. It may need a Digital to Analogue decoder which handles multiple sound source formats.

This is a design fault in the headphones. FCC regulations require that they switch off the transmitter if there's "no signal", which they determine to be an input volume below a certain threshold for a few minutes. That's annoying enough, but they decided that the receiver unit should respond to this by blasting loud static in your ears, rather than something like a gentle "no signal" beep and silence.

I find this design flaw unforgivable. Did they even test it?

Are you asking, if the Sennheiser HDR 120 II Headset used bluetooth to transmit the signals?
If that is the question: No!
Bluetooth transmission range is only a few meters - I think between 6 and 9 - which is, why bluetooth headsets are no option for me.
This Sennheiser headset uses RF (Radio frequency), the signals of which go quite a distance and through walls...

Hi guys, does this headphone come with separate cable so that I can use on wired mode?

No, you have to plug the sender and power it up as this is only an FM wireless headphone. I cant see the logic of wanting to use this device with a cord!
