Extra headphones for Sennheiser RS 135-9 [ Rowlan  Jan 21, 2019 ]
A
Have a set now but it is inoperable. The only thing I don't like about the system is that the head set does not fit well. If you bend over to pick something up they will fall off your head. [ Raymond  Jan 04, 2019 ]

We have had these earphones for years and the sound is perfect so I ordered another set.. [ Ida  Dec 12, 2018 ]
A
They are wonderful but they wear out after 10 years or so. Bought here 'cause they told me about how to check my receiver which was still very good, only needing the earphones. Worth a bit more than some nobody selling the same thing cheaper which might take up my valuable time dealing with a mess....Thanks Mac!!! [ Joan  Jun 23, 2018 ]

Q
no sound, I put new batteries in, still no sound? what can I do?
[ Kay  Apr 03, 2019 ]

Do you have static if the TV is not turned on. You should if it is tuned properly, and audio turned up. If no, chances are the transmitter is not transmitting. Try a different channel on the transmitter. Are you getting audio out of the TV? Try swapping left and right channels. Sounds odd, but try licking the positive end of the batteries. Saliva is a conductor. Hope something works.
[ Paris M.  Apr 04, 2019 ]

Addendum to my earlier email answer: The customer mentioned that she put in new batteries. In order for the headphones be charged/recharged on the cradle, I believe that only rechargeable batteries as those that come with the headphones should be used.
[ GARY  Apr 04, 2019 ]
A
According to the instructions, the headphones need to be charged for 24 hours before use. This is done by placing them on the cradle (which, of course, needs to be plugged into a power source). A red light will appear. I then plug the wire from the cradle into the phone outlet on my receiver. I turn on the receiver and the on switch on the headphones. Additionally, the headphones need to be tuned by moving the tune dial on the headphones (as one would tune a radio dial to get a station). I recharge the headphones on the cradle every night, follow the above procedure, and they work beautifully.
[ GARY  Apr 04, 2019 ]
A
Try turning the little thumb wheel at the bottom of the right ear cup. If that doesn't work, return them for another pair.
[ Richard  Apr 03, 2019 ]
A
Since you have new batteries we can move on to other possibilities . Easiest first. Have you tried to adjust tuning dial on headset? Also, if you have a new TV it may not have analogue sound capability which is required for the Sennheiser HDR 120. Check your TV settings to make sure. If not, you will need a digital to analogue converter. Also be sure that cable connections in back of the 120 are plugged in securely. Mine we very snug and difficult to get good connection.
[ Chris  Apr 03, 2019 ]
A
Make sure the sound is turned up sufficiently from the device that the transmitter is plugged into. Tune the headphones with the tuning dial so that they are receiving sound from the transmitter. It is like tuning into an old style transistor radio. Make sure the volume is turned up sufficiently on the headphones themselves. Hope this helps.
[ Cory  Apr 03, 2019 ]
A
Is your charging stand connected to the correct sound output. We have ATT and the charging station has to the connected to their equipment not to the TV. I have also noticed if the batteries are not pushed in all the way then we have no sound.

Q
RS 120 come with base chargeer?
[ Jonell  Mar 16, 2017 ]
1 answer
A
Thanks for your question. I'm sorry, no, there is no base included. On the main product page you can see what's in the box which is HDR-120 Wireless on-the-ear headset and 2 "AAA" Ni-MH rechargeable batteries (1.2V/600 mAh). For the base to be included you would have to purchase the RS 135-9 at the link below, hope this helps. https://www.crutchfield.com/p_143RS1359/Sennheiser-RS-135-9.html
