With WiFi speakers, you can stream music from your smartphone, tablet, or laptop via your wireless home network. You can connect most speakers to each other for a multi-room setup. The speakers have to be from the same brand most of the time, so the connection is smooth. So you can listen to the same music in every room in your house. That's why WiFi speakers are also called multi-room speakers. You can easily control a WiFi speaker with an app from the manufacturer. Some WiFi speakers have a built-in microphone, so you can control them with your voice. You can also use them to control your Smart Home.
