Wireless headset issue with SENNHEISER on TV

Have you tried moving the transmitter of this headset?
The SAT decoder may be interfering with this transmitter.

yes, I tried that too, no noticeable difference...

Hi.
Do you have the possibility to test the socket on the TV with another headset?

To return to the distance of the transmitter headset from the decoder, I imagine it's connected with an "extremely long" audio cable (30 or 40 centimeters).

You have a test on your Hi-Fi system. Is this system in the same cabinet or far from the TV setup?

Is there any other device emitting waves in the immediate vicinity of the headset transmitter (Internet Box with WiFi enabled, video transmitter, etc.)?

If not, if possible, try the headset with a device that has a headphone output (MP3 player, cassette player, etc.). Once away from the decoder, and another time with the transmitter "in its place."

Another possibility is to try with the TV but with the decoder "off."

Here are some possible interference sources to look into.

Well! It's also a solution.
