Today, Wi-Fi and Bluetooth are common features on most speakers. While both are convenient features, speakers pair differently via each connectivity method. For Wi-Fi speakers, you can control the speaker via smart devices on the same Wi-Fi network. By being on the same network, users can play music across multiple speakers. On the other hand, Bluetooth sends signals within short ranges (normally between 15 feet to 30 feet) to a speaker from a particular smart device.
