Not only smartphones but also modern PCs support Bluetooth. And since modern Bluetooth earphones can be registered with multiple PCs/smartphones (multi-pairing), it is possible to share one Bluetooth earphone with a smartphone and a computer. You can use your favorite Bluetooth earphones on your smartphone when you go out, and on your computer when you get home. However, when trying to use Bluetooth earphones on a PC, they may connect to a smartphone. Conversely, if you try to use it on your smartphone, it may connect to your PC. If you pair your Bluetooth earphones with multiple smartphones/PCs, you may not be able to switch between them as you wish.
It is possible to share one Bluetooth earphone with a smartphone and a computer, but the reason is the "reconnection" function when the Bluetooth earphone is turned on. An increasing number of Bluetooth products have the ability to remember the last connected device and automatically reconnect to that device the next time the power is turned on. Reconnecting is convenient, but it is important to note that the connection is limited to the last connected device. To avoid falling into this "reconnection trap", turn off the Bluetooth function of the smartphone/PC you do not want to reconnect to before turning on the Bluetooth earphones. Automatic reconnection will not be performed, but you can connect manually by opening the Bluetooth setting screen of the smartphone / PC you want to connect and tapping the name of the Bluetooth earphone, so it will not be a big burden.
