I have been using Philips SHC8545 wireless headphones wit my Mac to listen to the radio (internet). This means I pick up and move the Mac close to the docking station so that I can plug the headphones 3.5 mm stereo plug.
I then got an ipod (3rd generation) and thought it would be easier to move the ipod (lighter) instead of the Mac, to the room where I keep the headphones docking station. Tried to use the headphones with the ipod to do the same thing (listen to the radio) but after I plug in the 3.5 mm stereo plug I get no sound in the headphones no matter what I do. Just for comparison if I plug into the Mac next to the ipod-it works.

I don't really understand why it does not work with the ipod. It seems to me that it should be pretty straightforward.
Any ideas?

Thanks !
