Since you did not go into detail about how you connected the headphones I will make some assumptions

If you plugged the RF connectors into the back of the amp.. make sure to note what that output is.. and that the output is selected on the amp. Then turn the sound on the amplifier up slowly.

The green light indicates you have some type of signal activating the headset.. if you have the headphones plugged into a tape out connection and your amp allows this connection to constantly act as a monitor.. you may be getting enough of a signal to activate the base.. but not enough of a signal to generate audio as that connection is a fixed signal and pretty much unamplified..

When experimenting with outputs on the amp.. remember to turn the amp off when switching connections.. and turn the volume down before turning it back on.. always turn the volume down between selecting outputs ..

Finally verify the headphones work by simply plugging them into a headphone jack..(if you did not get that connector you can pick one up at radio shack) and turning the volume up slowly on the amp..

Good luck

I can only get static on my rs 120 head phones


Sennheiser remote/cordless headphones are ordinarily very dependable. From your description it sounds like the problem is with the base unit. Try power-cycling the base with the headphones sitting on the charger cradle (red charging light must be on when you do this) - Unplug the power cord for about 10 or 15 seconds then plug it back in. This action should cause the base and the headset to go through the automatic pairing process. Once the base is paired with the headset, it should begin working again. Check also the channel pushbutton on one of the headphones. Hope this helps!!

How do I get sound to my Sennheiser RS120 wireless headphones when it shows as working properly?


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

No audio just static


Surely the instructions for your new Samsung TV provide at least minimal information regarding what does what.

No green On/Off light. Charge light is red. I hear only static.


Two things.. Check the batteries..
Also.. since these headphones have to have a signal sent to them to activate transmission (green light simply indicates they are receiving a signal) it can take a few moments after the signal begins to activate them.
I would hazard a guess that when you unplug the cables and then plug them back in.. the feedback that generates activates the base much the same as a regular audio signal would
Finally.. make sure the source is a fixed output.. if not.. and its variable..you will have to increase the output or volume to activate the base..

Good luck!

There in no green light on RS 120. There is a red light on indicating that the headphone is being charged. Why I cannot use non-chargeable AAA batteries?


The green light only comes on when it is receiving an audio signal.

Standard batteries will work.. if you NEVER use the charging station.. and plan on replacing them every x number of hours used.. IMPORTANT.. if you forget.. and place the headset on the charging station with standard batteries.. they will probably rupture.. and may well ruin the headset..

If you decide to replace the chargable batteries.. make sure you replace them with the right size and type..

Audio from tv is not restored by turning off power on headphones


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

RCA wireless headphones


Hey, my rca whp141 is incredibly quiet. Go ahead and turn the volume up on the TV.
If that doesn't work make sure
  • The headphones and headset are on the same channel (like 1).
  • the transmitter is on and working (Power: GREEN LIGHT)
  • the headset is on and working (GREEN LIGHT)
  • the headset is receiving a signal (St: GREEN LIGHT).
Hope this helps.
