Question about Sennheiser RS 120 Consumer Headphones
I have my headphones on with the transmitter plugged into my computer. It works for approximately 15 minutes before the transmitter stops transmitting a signal, the green light (on/off) goes blank and all i hear is a loud static sound.
I had the same problem when I plugged it into a new HDTV. The problem was that the sound on the TV was set too low. The transmitter has a feature that automatically turns off when the signal is off or too low. Try turning up the TV volume to a high/higher level and it should solve your problem. Using the headphone jack with the white input allows you to use the headphones while bypassing the TV speakers.

Unfortunately these headphones have a “feature” that shuts them off after a set amount of time has passed. If no audio signal is detected.. after x number of minutes.. off they go.
A great feature for extending battery life.. a poor feature when using with sources that often have long pauses between signal output.. like using with a PC.. Often when listening to music while working on a document.. the music ends.. and a long pause ensues.. and the headphones turn off.
You need to turn them on and off again when you are sure an active audio signal is being sent to the base unit.
There is no workaround..
Since your problem doesn’t state they quit working during listening.. the above answer is all I have for now.
Other obvious things to check.. batteries.. and connections.. especially the connection on the base unit.
Best of luck

If you're using a mac, I've made an instructable on how to make this a little more bearable..
I'm sure there is a way of doing it for a pc using a batch file or something but I'm not too up on my pc programming anymore..
Hope it helps..

First thing is you need to have a signal going to the headphones for them to work.
If you are getting a signal the green light should be lit.
If only the red lamp is lit the headphones are not getting a signal.
If hooked into a television you should have them plugged into a Fixed Output not variable output..
If you only have a variable output then you must turn the speakers off on the television and then turn the volume up on the TV in order to send a signal to the headphones.
If you are using a amplifier make sure you are using the correct output. Tape Monitors generally will not work as this output is not amplified.
Lastly try using an rca to headphone adapter and plug them into a headphone jack.
