Even though getting a Bluetooth adapter for your system is not that complicated but you need to know what will suit your needs the best. Here are a few factors that you should consider before making the purchase:

  • Bluetooth Version

You need to get a Bluetooth adapter which utilizes less energy and is backward compatible with those devices which have a previous version of Bluetooth. For the same, any adapter with Bluetooth version lower than Bluetooth version 4.0 will surely disappoint you.

Bluetooth ve4.0 will offer you better stability and more range to connect even those devices which are at a distance.

  • Maximum Bluetooth Range

The transmission range of a Bluetooth device is determined by the class of Bluetooth it belongs to. You can find both Class 1 and Class 2 Bluetooth adapters in the market which offer a range of 100 meters and 10 meters respectively. 

Class 2 Bluetooth adapters are perfect for use if you just need to connect your wireless keyboard, mouse, or a headphone.

Aside from these two main features, a USB Bluetooth adapter should support the wide range of Bluetooth accessories that are available out there. Also, it should be compatible with both PC and other devices with other operating systems.
