What should you look for in a good Bluetooth adapter?
Before you go grab the first adapter you see, there are a few factors to consider when purchasing a USB Bluetooth dongle. Learning about these factors first will save you the potential hassle of having to return your purchase. The following is a rundown and brief description of all the relevant lingo.
Like all computer tech, Bluetooth is constantly evolving at an accelerated rate. There are multiple versions of Bluetooth on the market at any given time. The higher the version number, the faster and more stable the connection will be. Try to shoot for a device with at least Bluetooth 4.0 for the best experience.
Operating system compatibility
USB devices must install drivers on your operating system to be compatible with your computer. While most drivers will install on Windows, there are many that won’t recognize Mac OS or Linux. If your computer is a Mac or you have a Linux kernel installed, be sure to check that the adapter is compatible.
Even though the connection is wireless, there is still a limit to how far it extends. Determine how far way your two devices will be before buying an adapter. Most commercial adapters have a range of about 30-60 feet.
Bluetooth adapters are divided into class 1 and class 2. Class 1 devices are primarily for industrial use. They have ranges that can extend hundreds of feet to account for large working spaces. For this reason, most people are perfectly fine choosing a class 2 adapter. Class 2 Bluetooth devices are primarily for commercial use. As stated above, Class 2 devices hardly ever extend beyond 60 feet.

Now that you know what to look for, you can find the Bluetooth adapter that perfectly suits your needs. To save you some time, here is a breakdown of the most viable options in 2021. This list will surely contain the Bluetooth solution that you seek.
