Questions about Sennheiser Rs 2000

U-bolt tension not adjustable. Minimal pressure. No great pressure on ear.

Transmission is by radio. It works perfectly well throughout the room where the transmitter is placed. Obstacles don't get in the way

I have connected my headphones to the UPC box (not directly to the TV), which is why other people in the room hear the sound from the TV (for the headphones this then results in a slight echo, but this is not very annoying).

Since I am a UPC customer, I can connect the headphones to the box and a second person can then continue to listen directly via the TV, unfortunately with a small echo effect for the person with headphones ...

Hello and good evening The battery can only be replaced by Sennheiser itself according to the manual; The Sennheiser partner in Switzerland would be Sennheiser (Switzerland) AG In the Luberzen 29 CH-8902 Urdorf ...and this is the direct "wire" to them: https://de-ch.sennheiser.com/service-support-kontakt LG

Unfortunately, I can't answer that. But call Sennheiser Switzerland, they are very helpful.

Yes, sure - go to the homepage of Sennheister Switzerland https://de-ch.sennheiser.com/sennheiser-ersatzteile . There you will find the plugs and their article no. Either order them online or call the customer service and order them there. I hope the answer is sufficient for you.

In principle yes, but as far as I know unfortunately not at digitec, but at other Swiss suppliers at approx. CHF 110. A maximum of 2 headphones can be paired with one transmitter.
