SENNHEISER Wireless Headphones RS 120 Closed

Question

Hello,
I just acquired a SENNHEISER RS 120 wireless headset to allow me to listen to the TV without disturbing my family at night, but unfortunately, I'm experiencing a transmission problem.
It worked well for some time, but then (around midnight or one o'clock) it started making a "pssssshhhh" noise for no reason. Despite several attempts to change the frequency, it didn’t help.
I made a new attempt the next day during the daytime to test if there was a problem with the headset, and for 4 hours (I was moving around the house and not sitting in my chair), there was no sound issue.
The next evening, I tried the experience again, and once more, after a certain time (around half past midnight), there was no sound, but a deafening "psssshhh" in my ears. The green light on the headset base (which indicates transfer) goes out, and I have to disconnect the base and reconnect it for the headset to work again, but unfortunately, only for a few minutes.
I read that there might be an automatic standby mode.
Could someone help me solve this problem?
Thank you in advance for your help.

Hello
User of a Sennheiser headset of the same model but on another TV, I noticed that this headset requires a certain sound level not to cut off (the SHHH). There is on my TV a mini jack stereo headphone input whose volume level is adjusted in the MENU/SOUND/HEADPHONES separately from the speaker volume level of the TV (thankfully). The INPUT LEVEL indicator on the base actually blinks if the sound level intended for the headset is too low or too high.
If that can help you?
Cheers

Yes, I'm interested too. It's been 5 years since my same-brand headphones have been in a box in the attic for the same reasons, and I've only used them two or three times...

I do have a little idea... as soon as the sound source is cut off, they immediately go into standby. When we listen to an mp3, and at some point there's no sound, the mp3 system makes it so that there's absolutely nothing, rather than a silence with a slight background noise inaudible to humans like in other uncompressed formats, and that's why it cuts off sharply, you see what I mean?

Now, this is just a hypothesis.

Hello
I also have this equipment to my greatest satisfaction, so I will try to help you with my experiences. I have a plasma television equipped with a headphone jack on the front (mini-stereo jack) and the headphone volume level at the jack is adjustable in the TV's SOUND menu (and independent of the volume control of the TV's speakers). The level displayed on the screen during adjustment should be at least about two-thirds of the range of the bar graph. The headphones deliver sound at the level you want with the dial included in the left earcup. The "Shhh" you hear corresponds to an insufficient sound level. The effective listening range covers the room where the TV is located and the sound easily passes through the walls in my house which are not made of concrete, as well as the floors. The limiting distance is noticeable when brief "shh" sounds are heard, especially when you tilt your head. Pressing the channel selector is only necessary once at startup to obtain clear sound. And should there be any neighborhood disturbances (your neighbor bought the same device as you!)
The top light turns on if the source sound is present, the bottom light blinks if the source level is too low. The battery light (middle) blinks (unnecessarily) when the battery (of the headphones) is charged
There you go, it should work to your greatest satisfaction
Happy New Year 2010

Hello everyone,
I’m glad my headset is working perfectly now.
I have a Samsung LCD TV. In the menu/settings, I changed the eco mode to Medium
Since then, I haven't had the sound issue anymore starting at midnight; the sound is perfect.
Thank you for your responses

Hello,
I also have the RS 120 and a Samsung LCD LE46B650.
The headset works perfectly with my computer, but on the TV, after 3 minutes, the green light on the base of the headset goes off, and there’s a huge "pssssshhhh" noise. When I plug it back into the TV, it works for 3 minutes and then it's the same again.
I tried setting the Samsung's 'ECO' mode to medium... same issue, configured the sound to 'external speakers'... same issue.
Thank you for your help.

Samsung support had me install the latest firmware on the Samsung but the same problem persists.
Then, on Bernorenard's advice, I increased the TV volume significantly.
And since then, no more issues... Should have thought of that.
Thank you very much, Bernorenard!

Hello,

I picked up a SENNHEISER RS 120 wireless headset that was working perfectly before, and when I try to connect it to my TV or my amplifier, I get no sound in the headset. What should I do?

Thank you for your help.

Hello everyone
Thank you for the information, I had a sound problem with the RS127
I think I have solved it after reading your various comments
The sound from my headset output was often at zero
I connected Bose speakers with an optical output and didn't realize that I had turned off the headset sound
Best regards

Hello,
Santa just delivered a RS 120 II to me.
I was also having issues with the connection between the headset and its base, and since I turned up the TV volume, no more problems and sound without interference.
