This video below shows how a RFID phone pouch can remove unwanted radio signals from the P-SB7.
If you use a external speaker be aware the wire to the external speaker will act as a antenna and still pick up signals close to it although this does not effect sessions as it would be a extremely rare case that you are less than 2 foot from a radio transmitter.
If you dont use a external and only the internal on the P-SB7 then it will block all radio.
We hope this helps as we was searching for a way to prove to skeptics when we get voices that its near impossible to be radio when we use this pouch.
