Listening to loud music with headphones is annoying - is there a jammer?
It annoys me when on a plane or train, when I need to concentrate, someone next to me is listening to music with headphones so loud that I can hear it. Then the whole headphone is useless. Is there such a device with which I can disturb the "waves"? I once noticed in the subway that someone had done it.
Of course, wireless headsets generally use Bluetooth channels or wifi channels to transmit sound, and wifi jammer can be used to shield surrounding wifi or Bluetooth signals. This frequency can be customized
