I have HDR65/RS65 Sennheiser wireless headphones. I disconnected them to move stuff around, then re-connected them. Now all I get is a 2 second cycle consisting of: 1 second of static that builds in volume, then 1/2 second of actual signal , then 1/2 second of nothing. I have new fully charged batteries and a new signal cable. Any ideas??? -Kevin

do you can to try mine? i never happen that problem

The first thing to do is to disconnect the Sennheiser wireless unit and try another headphone, preferably a cable type and see if both channels work. If the sound is OK on both channels, the fault is within the headphones. If you are lucky it will be the wireless unit plug or the cable and can easily be tested and repaired by somebody familiar with electronics. Otherwise you will probably need to have it repaired by a service shop or a technician. I hope the guarantee is stilll valid.

Dirty volume control on headphones. Try moving the volume control back and forth several times to clean off the contacts.

Hello,
Sennheiser sent me the manual.
Thank you, Eletta

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.

I have a plasma, and found when I plugged my HDR65 to back of the plasma audio out, it worked fine. does this help?

It sounds as if you are plugging the base into a standard headphone jack located on the Television set.

RCA Headphone jacks (incl mini) automatically stop the sound output to the main speakers on almost every set I have seen.. or home stereo.. etc etc

In other words you can take a standard RCA jack.. with nothing connected to it.. plug it in while the music or sound is coming out the main speaker.. and it will cut off the output to those speakers..

If you set has audio outputs on the back.. preferably Fixed Audio Out .. you will need to connect your base unit to those.. turn your set volume to 0 and adjust the headset volume using the control on the right ear-cup.

If you have variable audio out.. you will need to go into your TV sets setup menu.. turn off the speaker.. and turn up the set until you achieve a signal and decent volume through the headset.

If you are missing these connections.. your current “work around” is your only solution.

Best of luck

Well it could be interference from the TV, computer, or other 900Mhz device (some wireless routers run on this frequency).

I'm currently dealing with the same issue myself, if I find a solution I'll post back.

They need a minimum level of signal to switch on the transmitter.
Verify if it works on yet another system.
Make sure you have the right output on your Samsung.
Try to increase the output level of your Samsung...(up the volume, but it may be a fixed output..)
