An Apple tool designed to help the hearing impaired unwittingly allows vulgar criminals to spy on people.

The Live Listen feature loaded onto Apple’s wireless AirPods makes it easy for tricksters to eavesdrop on a conversation – by giving them super hearing.

The little-known tool is included in Apple’s latest version of iOS and appears as an ear icon once you activate it.

It helps the hearing impaired by allowing them to place their iPhone close to a person they’re having trouble hearing.

But people can commandeer Live Listen to snoop on their target by hiding their iPhone in the same room as the victim.

Anyone using the tool can simply turn up the volume on their iPhone’s microphone to listen through the AirPods.

The iPhone microphone will beam whatever is said to a trickster in a different room, up to 50 feet away.

Eavesdroppers can also use an Apple Watch to spy on people, leaving the watch in a room with someone whom they want to listen in on.

Apple fans expressed concern at the new feature on social media.

“AirPods can live listen now. SMH ! Men about to be caught caught lol,” one person tweeted.

“Just wait till all these new AirPod kids figure out ‘live listen’ and become amateur James Bonds,” another wrote.

“Using live listen to eavesdrop on my parents arguing and make sure my name isn’t dropped,” said one Twitter user.

Apple was not immediately available for comment.
