If it seems as though the transmitter signal is being received but there is no audio, disconnect the 3 or 4 pin connector of the mic and touch the different pins while transmitting to the receiver. If there is audio hum or buzz, the mic itself is probably dead. A wire could be off inside its connector.

Try to get a one track sound mixer and your problem will be solved.

More then likely you can get it at your local music dealer, and they might even be able to fix the mic for good.

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.

I thought this was another example of the proprietary world of Apple, whereas any non-Apple made or certified headphones/headsets with mic and/or volume control will not work with an iPhone or iPad (I am not sure about iPod). It took me many headsets to figure out what was going on. However, your headphones seem to be made for iPhone and sold in Apple stores. If this is the case, I will go back to any Apple store and talk with the tech people there about your situation.
