Question about Sennheiser HDR 120 Consumer Headphones

1 Answer

Sennheiser 120 green light goes off

I have had 2 sets of these headphones and stands. Everything worked fine with them for a few months. Now the red light goes on when charging but the green light no longer goes on and there is no sound to the headphones (besides static). The sound is set correctly and I even turned it way up, the channel is right but still nothing.

SOURCE: No sound coming through my Sennheiser wireless headphones

Turning the transmitter on and off (Fig. 5)
Turn on the sound source. This automatically activates the
transmitter and the green LED “ON/OFF” lights up. If the sound
source is turned off, the transmitter is automatically deactivated
after approx. 3 minutes (the LED “ON/OFF” goes off).
Note: The automatic level control only functions if the volume of the
sound source is sufficient.

SOURCE: There in no green light

The green light only comes on when it is receiving an audio signal.

Standard batteries will work.. if you NEVER use the charging station.. and plan on replacing them every x number of hours used.. IMPORTANT.. if you forget.. and place the headset on the charging station with standard batteries.. they will probably rupture.. and may well ruin the headset..

If you decide to replace the chargable batteries.. make sure you replace them with the right size and type..

SOURCE: No green On/Off light. Charge light is red. I hear only static.

Two things.. Check the batteries..
Also.. since these headphones have to have a signal sent to them to activate transmission (green light simply indicates they are receiving a signal) it can take a few moments after the signal begins to activate them.
I would hazard a guess that when you unplug the cables and then plug them back in.. the feedback that generates activates the base much the same as a regular audio signal would
Finally.. make sure the source is a fixed output.. if not.. and its variable..you will have to increase the output or volume to activate the base..

Good luck!

SOURCE: Sennheiser Wireless Headphone Stops transmitting signal

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.

Work fine for about 5 minutes than change to static


There's an auto-shutoff feature which kicks in when the audio input to the transmitter is too low. That's usually indicated by the green light on the transmitter turning off. Just increase the volume on the device connected to the transmitter, and you should see the green light come back on. As long as that's on, it'll stay transmitting and shouldn't just cut out to static.

Red and white cables?


My Sennheiser comes with a black and red cable. I plugged the red into the red in the back of the tv and the black into the white in the back of the tv and it works for me. Hope this helps.

I have a huge problem with these headphones (the Sennheiser HDR 120)... and my wife bought two of them... They have great sound on the computer, but once the green light turns off on the base? There...


The volume of the sound source (Mac) must be sufficient, otherwise the transmitter automatically turns off. Turn up the volume on the Mac, and turn down the volume on the headphones. There is no way to disable the Automatic On/Off function of the transmitter.

There in no green light on RS 120. There is a red light on indicating that the headphone is being charged. Why I cannot use non-chargeable AAA batteries?
