There is a possibility that internal speakers have to be turned off to direct audio output to the rear connector. You can confirm this by going to the initial set up procedure to disable internal speakers.

Sounds like the turbo. Get a reconditioned turbo as they are very expensive new.

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.

I had the same problem when I plugged it into a new HDTV. The problem was that the sound on the TV was set too low. The transmitter has a feature that automatically turns off when the signal is off or too low. Try turning up the TV volume to a high/higher level and it should solve your problem. Using the headphone jack with the white input allows you to use the headphones while bypassing the TV speakers.

Yes All batteries are subject to failure and eventually need to be replaced, some last longer than others it's a manufacturing consistency problem. ...

There's an auto-shutoff feature which kicks in when the audio input to the transmitter is too low. That's usually indicated by the green light on the transmitter turning off. Just increase the volume on the device connected to the transmitter, and you should see the green light come back on. As long as that's on, it'll stay transmitting and shouldn't just cut out to static.

Sorry I have not had that problem with batteries but have had other noises and I usually stop using the headphones for a while and hang them up and start again.

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!!

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

The television audio out is the way to connect them. If you connect them to the cable box you may have audio lag.

If it works with one, it would work with both unless you have it hooked up wrong or are not using the proper settings.
