Although it can be plugged into your PC for charging purposes, the Logitech MX Master 2S can only pair to your computer via a wireless connection. It's one of the few mice on the market with a proprietary receiver, but it can also be used over Bluetooth. You can switch between three paired devices through a button on the bottom of the mouse.
Note: As of 2023, there's a variant of this mouse called the Bluetooth Edition, which doesn't include the 2.4 GHz USB Unifying Receiver. While we tested the original model, we expect the performance to be the same. Since the Bluetooth Edition is designed to be used over Bluetooth, we're unsure if it would still work with a Unifying Receiver; if you have this variant and can confirm, let us know in the comments.
