Covert listening device

A covert listening device is a tiny thing that someone can use to secretly listen to other people's conversations without anyone knowing. It's like a little spy gadget that can pick up sounds and transmit them to people who want to listen.

Picture a baby monitor that parents use to listen to their baby while they're in another room, but instead of parents listening to their baby, someone else is using it to listen to other people's conversations without their knowledge.

Covert listening devices can be hidden in objects like pens, clocks, light bulbs, buttons, and even inside books. Sometimes spies hide it in someone's clothing, hair, or glasses so no one suspects that they're even listening.

It's important to know that using a covert listening device is not okay as it's an invasion of other people's privacy. It's best to speak openly and honestly with people instead of using sneaky gadgets to listen to their conversations.
