Best USB Bluetooth Dongles for Windows

A Bluetooth dongle or a Bluetooth adapter is a USB device that connects to a laptop or a computer and gives it Bluetooth connection capabilities so that you can connect your external devices to your PC.

Bluetooth adapter comes in handy when you do not have built-in Bluetooth capabilities and also because they provide a greater range or stronger connectivity.

Some Bluetooth dongles aren’t the best for multiple uses and some are purely created for a designated device like a mouse or headphones.

You should also consider if you want one that has a good range or if you don’t mind having one with a lower range and stronger connectivity. Other factors include the Bluetooth version 3.0 or 4.0 or pairing features like automatic pairing.

Our Overall Number One Pick:

The Asus BT-400: This dongle is the overall best performer in all categories when it comes to Bluetooth Adapters. It provides connections to kinds of peripherals and is compatible with all devices. Furthermore, it offers stability, a small and comfortable design, and ease of use. The only downside we see with this one is that it is slightly more expensive than the other dongles but it is sure worth its price.

Cheaper Alternative

The ZexMte Bluetooth Dongle: This brings all of the Asus’s best qualities together and provides it at a cheaper price. Obviously, it does not have the exact capabilities of the Asus but it is not far off. The design, as well as a comfortable fit but, has a lower quality in comparison to the Asus. If you have a lower budget then this is your go-to dongle.

Musical Dongle Pick

The Avantree Leaf: For audio peripheral devices, the leaf offers connectivity speeds that favor audio devices and offers specific audio codecs to improve quality and give users the best experience possible.
