I am not familiar with the "classic woodpecker" sound, can you please
describe it? I am assuming that if you just listen to the music on the
telephone instrument you do not get any noise?? When you are listening just
on the telephone, is it live - being downloaded as you listen, or is it music
that you have previously downloaded to the telephone?


It is the GSM noise cydrome references:

I do not get the noise when listening on the cellphobes speakers (But
my fellow commuters would probably complain).

I only gets the noise on the headphones when the active noise-canceling
electronics is turned on, not when it is turned off and it is working
like a regular headset.
