    It is a weird beeping sound? I've had that with speakers but not headphones. It should be normal because all consumer grade electronics are required to be subject to interference in order to comply with FCC standards. ;)

    can someone provide a more in-depth explanation.. cause i get that too.. although i never heard any voices or anyone talking whatsoever rather i just receive a lot of static that sometimes i react by taking off the headphones quickly.. - i mean if we understand why it happens perhaps we would kno how to prevent it :p

    its simple explanation, its like how any wireless transmission works

    you send out radio waves, which should be picked up by an antenna (i believe the waves induce electrical energy in the antenna, thus reproducing the wave signal down the antenna)

    now if you go through a path of radio waves, your headphones act like an antenna and end up picking up signals

    its called interference and happens to most wireless devices. The way to prevent this is to shield the wire so the radio waves never reach the wire. But its not necessary for a pair of headphones unless your willing to dangle 10mm thick wires off your head

    Shielding the cables alone won't eliminate the interference. The audio source will also be subject to the interference. It shouldn't occur frequent to cause a problem.
