The iEavesdrop app redirects internal microphone, external wired microphone or line input input audio to any Bluetooth audio device such as AirPods so that you can use your phone as a stealth listening device.
Using the correct line input cables, audio from any device such as an external microphone, in-flight entertainment or portable gaming device can be routed to your AirPods or other Bluetooth device.
iEavesdrop will work with all iOS devices.
THIS APP CAN ALSO BE USED FOR MANY OTHER PURPOSES SUCH AS A BABY MONITOR, HEARING AID OR ANY OTHER APPLICATION THAT REQUIRES YOU TO LISTEN IN OR ROUTE MICROPHONE AUDIO TO A BLUETOOTH DEVICE.
