Modern Android phones with Bluetooth 5 and later versions can connect to multiple Bluetooth devices simultaneously. This means that you can connect two or three different wireless earbuds and speakers to your phone at the same time.
If you have various Bluetooth devices connected to your smartphone, you can switch the audio output to any device you prefer. The audio is not played through all connected devices. If your phone is connected to your wireless earbuds as well as your Bluetooth speaker and you get a call, you might not want to answer the call on the speaker. Or you might not want to watch a video on your speaker.
