Okay kiddo, so you know how in movies and TV shows, sometimes there are scenes where people are talking to each other on phones or radios, and you can hear them really clearly even though they're far away? Well, those people are probably using something called a clipse!
A clipse is kind of like a little microphone that you can clip onto your shirt or jacket. It's really small, but it can pick up sounds really well. So, if you're talking to someone on the phone or on a radio, you can clip the clipse onto your shirt, and then the person on the other end will be able to hear you really clearly, even if you're not holding the phone or radio right up to your mouth.
Clipses are really handy because they make it much easier to talk to people when you're busy doing other things, like driving a car or cooking dinner. Instead of having to hold the phone or radio up to your mouth, you can just clip the clipse onto your shirt and talk normally.
So, that's what a clipse is! It's just a little microphone that you can clip onto your clothes to make it easier to talk to people.
