Question about Sennheiser HDR 120 Consumer Headphones

1 Answer

Why are my sennheiser HDR 120 wireless headphones not transmitting any sound

Why are my headphones not transmitting any sound? The headphones are charged and plugged into the TV. I am not sure if I have them plugged into the right place. Also On the charger stand there is a channel switch that has 3 positions: right, middle and left, I am not sure which position it should be in. Lastly there is a tuning dial below the volume dial-do I have to use that to get sound?

You plug the charger base in the AUDIO OUT of the TV, not the headphones. You wear the headphones. You use the volume dial to lower or increase the volume. And don't forget to plug the base in a power outlet and turn on the headphones.

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.

First of all if the right side is working the wireless is working alright and the fault is in the processing section, the left audio preamplifier , the left side power amplifier and the left side earpiece.

So you might have to test with a audio signal to confirm from the preamplifier, the low-power amplifier driver for the earpiece and the earpiece.
Once this is confirmed the focus can be the wireless section, possible fault in the receiving section.
The use a a multimeter to check and knowledge of electronic circuits is necessary to check around this section. Please check and respond.


The advice/tip given is with the belief that you are competent. You must attempt to do it yourself only if you are technically/logically able, especially when dealing with delicate devices, damaging while trying to open, Probing electrical/electronic circuits with high voltage or delicate components. Since the advice given by me is with the inputs provided and not based on a visual inspection, there can be further reviews required in some cases.

How do I charge batteries?


The headphones will automatically charge wirelessly when placed in the cradle that should have come with the package. To make sure the headphones are placed correctly, a red light should illuminate letting you know they are being charged and are properly placed.
