SOURCE: 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.

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.

How do I charge batteries?


The headphones will automatically charge wirelessly when placed in the cradle that should have come with the package. To make sure the headphones are placed correctly, a red light should illuminate letting you know they are being charged and are properly placed.

HDR 120 PHONES. Sound on right phone has dissapeared but right phone is ok. Batteries have been checked and are fully charged. Any suggestions. I have checked all the connections and all look solid on both...


Hi, What test did you preform to know the right phone is OK? Connections can look solid to the naked eye but not be the case. What are you using to test these phones? Make sure the the plug you are plugging your jack into is functioning properly so you know you will get a proper test of the phones themselves. With the phones on your ears and plugged in and music playing can you wiggle any of the wires or connections and hear any crackling? This will give you a good starting point to address. Good luck.

Have not used them for a while


These systems have some signal detection, so needs an input to fire it all up. That is the same for the greenlight, when initially switched on for my HDR 120.
