UGREEN USB Bluetooth 5.3 Adapter | 35995
The UGREEN CM591 (#35995) is a small black USB-A dongle that adds Bluetooth 5.3 to a Windows PC or laptop. Plug it in and you can connect Bluetooth devices such as headphones, a mouse or a keyboard to a computer that has no Bluetooth, or whose built-in Bluetooth is not working.




Bluetooth 5.3: The adapter uses Bluetooth 5.3, the version stated by UGREEN on the product and its packaging. It works as the Bluetooth connection of the computer for wireless peripherals and audio devices.
Plug and play on Windows: On Windows 11, 10 and 8.1 no driver installation is needed: you plug the adapter into a USB-A port and Windows sets it up. This makes it a quick fix for desktop PCs that came without Bluetooth.
Several devices at once: You can connect more than one Bluetooth device at the same time, for example a mouse, a keyboard and headphones together. If two audio devices of the same type (such as two headphones or two speakers) are connected, only one of them can play sound.
Compact design: The dongle is very small and can stay plugged into a laptop all the time. It also has a lanyard hole.
Who it's for / Works with
Windows 11, 10 and 8.1 computers and laptops with a USB-A port, used with Bluetooth headphones, mice, keyboards and other Bluetooth devices.
Good to know
Windows 7, Linux and macOS are not supported. When several audio devices of the same type are connected, only one plays audio at a time.
