best bluetooth adapters

A PC without Bluetooth connection is not a problem anymore. There is no need to spend a fortune on a new laptop as you can just choose one of the best Bluetooth adapters and save your hard-earned money.

If Bluetooth receiver is a panacea for audio systems then Bluetooth adapter is the best choice for any laptop or desktop computer without Bluetooth connection. It’s a tiny thing, which sometimes may look like a USB Wi-Fi adapter, and which enables various connections. Nowadays Bluetooth adapter is a kind of a must for the owners of multiple wireless devices.

How to Choose The Best Bluetooth Adapter

When selecting Bluetooth adapter remember to check all crucial features any good product must have. Here’s the list of characteristics you should consider before choosing the best of the lot.


Obviously, the best Bluetooth adapter should support your PC and all devices you are going to connect it with. Almost all Bluetooth dongles are compatible with Windows OS but Linux or Mac OS can become a stumbling block. The best thing is to buy a highly compatible adapter which will serve you even if you decide to purchase a new PC with the other operating system.

Some operating systems support Plug-n-Play option (e.g. Windows 8/10). It means that you don’t need drivers to install a Bluetooth adapter. If such an option is not available then you can get drivers on the official website or on the CD attached to the product.

Bluetooth Technology

Another important thing to take into account is a Bluetooth version. Don’t buy Bluetooth adapter with Bluetooth version lower than 4.0 as its quality will definitely disappoint you. Bluetooth v4.0 and higher provides more range, so you can connect devices which are farther away from each other.

In addition to this, such version consumes less energy and that’s the crucial point for laptops. Note that if your dongle has Bluetooth v4.0, it is also backward compatible. It means that you can connect it to any other device with older Bluetooth versions.

Class 1 or 2

Choosing your best Bluetooth adapter, don’t forget to pay attention at its class. Class 1 adapters are suitable for industrial devices which need Bluetooth connectivity at long distances. As to class 2 adapters, they would be the best choice for consumer devices that aren’t aimed at long distances.

Transmission Distance

As you can already guess this feature depends on the pre-cited characteristics. Bluetooth adapters of class 1 can have a transmission distance of up to 330 feet. Class 2 dongles usually offer an operation range of only 33-60 feet. Still, always consider the quality of the connection. Sometimes devices with the same range may have different performance.
