If you take a look around the gym or on the bus, you'll notice that Apple's AirPods are proving to be a very popular purchase.
However, it has been revealed that a trick can transform the AirPods from a merely handy, cord-free way of listening to music into basically modern spy equipment.
A software feature of the new operating system contains a 'Listen Live' feature, which was created to help hearing-impaired users.
It effectively boosts your hearing by getting your phone to work as a sort of microphone, allowing you to hear your friends talk more easily if you place your iPhone within close proximity to the person speaking.
However, it turns out that the AirPods have a 15m reach with their connection to the phone, meaning that you could leave your phone in a different room and, if you were so inclined, listen in to other people's conversations.
All we'll say is use this new-found power wisely...
