First thing is you need to have a signal going to the headphones for them to work.

If you are getting a signal the green light should be lit.

If only the red lamp is lit the headphones are not getting a signal.

If hooked into a television you should have them plugged into a Fixed Output not variable output..

If you only have a variable output then you must turn the speakers off on the television and then turn the volume up on the TV in order to send a signal to the headphones.

If you are using a amplifier make sure you are using the correct output. Tape Monitors generally will not work as this output is not amplified.

Lastly try using an rca to headphone adapter and plug them into a headphone jack.

Blue light is not blinking or on at all when i set phones on charging dock.

ck that batteries are installed correctly and contacts are clean. Put the old batteries in, if it is not trying to charge them, sounds like the charger is bad.

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...

Try connecting them to an MP3 player or connect wired headphones to the same source to make sure the sound source is working correctly. If that works, verify the voltage on the batteries is 2.4 volts after charging. Mine stopped charging fully and the headphones wouldn't work at all, but when I connected a couple of AAA batteries to it in series, it worked great.

The headphone does not turn on anymore

I have got exactly the same problem with mine. Mine are RS140.
So if there is anybody that can help with this I would be very happy to find out what the problem is (as only used them twice)

Brand new Sennheiser RS140 headphones stopped working

Mine is a bit older (2yrs), but I have exactly the same problem. Absolutely no sound from the headphones (no beeps). I also tried new batteries, but still nothing.

If you have a solution, let me know!

Headphones cut in and out - distorted sound

Dance_to_it -
I have had these great headphones over 15 years (I think!)
1. Are the batteries getting a full 8 hour charge?
2. Have you tried all 3 channel options?
3. Is there anything else close by that is an RF transmitter or receiver? If so, move the headphone base or other RF instrument away from each other.
4. If these are the original batteries you probably need new ones.
5. When purchasing new batteries I recommend original equipment Sennheiser BA151 batteries, not any other brand. I have tried 3 or 4 other brands, all with less than satisfying results. I have no affiliation with Sennheiser corp., just a consumer of their products (and Grado's for wired headphones)
Good luck!

Sennheiser rs-126 connection

Yes, you may. RCA connections are universal, just don't connect an input lead to an output jack: you might damage the jack.

Did you try charging the batteries with another charger?

Hissing and poor sound quality

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.
