เสร็จซะที

But once you block the path with walls or other sources of interference, the signal will start to become choppy or completely cut off. Be warned that your body can also block the signal. Cupping my hands completely around the transmitter would pretty much turn the signal to crap beyond only a few feet from the BT receiver. In most cases, as long as I'm witin a one or two feet, the signal still comes through, but the more I block the signal and the further I go, the more the signal would degrade, as is to be expected.
