SOURCE: No sound coming through my Sennheiser wireless headphones

Turning the transmitter on and off (Fig. 5)
Turn on the sound source. This automatically activates the
transmitter and the green LED “ON/OFF” lights up. If the sound
source is turned off, the transmitter is automatically deactivated
after approx. 3 minutes (the LED “ON/OFF” goes off).
Note: The automatic level control only functions if the volume of the
sound source is sufficient.

This worked for me (this solution was posted on another thread). Unplug the base and take out the headset batteries. Wait 30 seconds. Reconnect. Turn on head set. I could hear immediately!

Why don't either the charging or on/off lights come on when my transmitter is plugged in?


Bad connections. Plug in and withdraw multiple times, It may serve to "clean" and polish the contacts. Hope it works.

Sennheiser HDR120 - missing transmitter / alternative OR replacement?


The system is working in the 860 Mhz range, so not that common. Most of the time it is cheaper to by a complete new system then to tray to buy components. Just keep looking in the thrift stores you find a transmitter for this headphone for a good price.

assuming the battery is charged, have you tried to switch to a different frequency band, etc.?
check page 28 of the user manual for possible actions when there is no sound in the headphone.

I feel that the 'normal' background hiss is a problem that I would like to minimize with the sennheiser IEM 300. I'm currently using the IE 4 ear phones. Would a different/better earset with maybe a...


No, that will not help. The his is a function of the receiver NOT receiving a signal from the transmitter as they apparently do NOT have a "squelch" circuit to mute the receiver noise when no signal is being received. The noise level when no signal is received is pretty high and apparently the volume control is not enough to reduce the hiss.

To solve this, LEAVE the transmitter ON and make yourself a switch at the receiver. DO this using one of those little in line lamp switches that fit on zip cord. Make one on a short length of zip cor with mating connectors to fit the received jack and the headphone plug. Don't worry about unshielded wire as the impedance is very low. Then you use this switch to mute the headphones when you want to. There are other switch types you can use, I am just suggesting what might be readily available to you.

Sennheiser SHOULD have include a mute switch on their unit as turning the power off on the receiver would be a pain. They could have used a volume control with switch to kill the audio line out... simple solution... oversight on their part.
