Check your connections

 

Check the backs and bottoms of your phones and computers for strange devices. Scan the length of every transmission wire leading into and out of your house. Even if you don’t find a listening device, keep an eye out for a stripped section of cable—that’s where a device was or will be connected. Occasionally disassemble your phone and look for small, extraneous microphones. These may not be obvious, so look carefully, and choose wisely before you decide to remove something from your phone and smash it with a hammer. What you think is a listening device might just be your telephone’s brain.
