A Bluetooth adapter is a small device that connects to the USB port of your motherboard and pairs itself with any device you have wirelessly to work with your PC. With the invention of these adapters, life has become easy for many as it can be used to wirelessly connect mice, speakers, headphones, and anything that supports connectivity over Bluetooth. However, not all the adapters available are created with quality in mind and there are many factors that can affect the performance such as the Transfer Rates, Compatibility, etc. We’ve picked the best of these for you considering compatibility with yet to release devices, transfer rates, OS compatibility, etc.

2. ZEXMTEE Bluetooth USB CSR 4.0

  • A large range
  • Poor connectivity with Bose headphones
  • Slower transfer rate with Windows 7 or older

2,549 Reviews

Bluetooth version: 4.0, 3.0, 2.0 and 1.0 | Transfer rate: 3Mbps | Compatibility: Windows 10, 8, 7, Vista, XP

Moving on, we recommend the ZEXMTEE’s Bluetooth CSR4.0 adapter for your needs. With next to zero reported connectivity issues, this dongle is an amazing choice for a quick solution.

This adapter is compatible with all versions of Windows (10, 8, 7, Vista, XP) as well as Linux. It can be used to connect various devices including headphones and keyboards etc. However, Bose headphones and speakers struggle sometimes to get paired with this dongle. You might need to turn it on and off a few times to get the trick done.

It’s very small size allows it to be properly plugged in a USB 2.0 port without blocking any adjacent USB ports. The Broadcom chipset is able to provide dual-mode data transfer at rates up to 3Mbps. It has a coverage distance of 10m in an open area, however, with enclosed environments we have experienced a working range of up to 13m.

The ZEXMTEE Bluetooth dongle is a very cheap solution for all sorts of purposes. Connections can be made with PC and console controllers. Moreover, it is on sale for an even cheaper price.

3. Asus BT-400

Bluetooth version: 4.0, 3.0, 2.0 and 2.1 | Transfer rate: 3Mbps | Compatibility: Windows 10, 8, 7, Vista, XP and Linux

Asus has been in the computer industry for decades now. With those years, they’ve familiarised themselves with every product related to computer needs. For our spot of number 3, we have Asus’s very own BT-400.

Like the previous ones in the list, this one too is of very small size and can be neatly tucked away. It’s compatible with all versions of Windows and Linux too. We witnessed a degraded audio quality with a headphones connection. But, it wasn’t enough to raise any major concerns.

With Bluetooth 4.0 and backward compatibility with 3.0, 2.0 and 2.1, this dongle covers supported devices of all sorts. Moreover, it has a feature called Bluetooth Low Energy which reduces the power drawn by this dongle to work. This may not look much but goes a long way when connected to laptops as it drains much less power.

So, to answer the question, yes- the Asus BT-400 is a good product for people looking for a Bluetooth connection in their older devices. It is a bit more expensive than the rest of the adapters in this list, however, with the name Asus attached to it, you’re sure to get the best performance possible.

4. Sabrent USB Bluetooth 4.0

With Long Range

  • Effective range of 40ft
  • Object doesn't need to be in line of sight to establish connection
  • Unrelated on-screen notification comes with software
  • Very buggy software
  • No plug n play for Linux

945 Reviews

Bluetooth version: 4.0, 3.0, 2.0, 2.1 and 1.1 | Transfer rate: 3Mbps | Compatibility: Windows 10, 8, 7, Vista, XP and Linux

The name Sabrent may sound unfamiliar to a lot of people. It’s quite an unknown brand but don’t let it alarm you. Their solution is also a very effective and reliable one but with a couple of drawbacks. Keep reading to find it out.

Sabrent’s USB adapter is also compatible with all versions of Windows- as is everyone- and features plug n play. It should be noted that plug n play with this adapter works only with Windows 10. The installation is straightforward however, the software is not even close to what should be considered ideal. It installs an unrelated program that displays notifications on-screen for pressing caps lock, num lock, etc. Moreover, these notifications are not hidden with Windows’s game mode and end up ruining the game experience. You’ll be much better off using this without the software.

This dongle also houses Bluetooth 4.0 technology along with the backward capability for 3.0, 2.0, 2.1 and 1.1 versions. Moreover, with this small little adapter, you can access the internet via a Bluetooth phone or PC with an internet connection. We were unable to really find a good use for it but for those looking for this feature, Sabrent has got your back. Printers, headphones, keyboards, mice and all other devices can be connected using this adapter.

Sabrent, an unknown company, provides a bang for buck performance with this Bluetooth adapter. It has a few drawbacks such as the software bugginess but, work your way around that and this dongle will leave you with good memories.

5. Onvian USB Bluetooth Adapter CSR 4.0

Cheap Bluetooth Adapter

  • Stable and disconnects free connection
  • Cheap solution
  • Only connects with PC
  • No official warranty
  • Only works with Windows 10 and 8

27 Reviews

Bluetooth version: 4.0, 3.0 and 2.0 | Transfer rate: 3Mbps | Compatibility: Windows 10, 8

At last, we have the cheapest product for you. Despite the low price, the Onvian Bluetooth adapter still manages to do, the few things it is capable of, right.

Compatible with all Windows 10 and 8, this is the simplest one out there. Plug it in and you’re set. Alas due to it being restricted to plug and play only, people using Windows 7 or lower will not be able to connect their devices. The previous version of Windows does not support Bluetooth plug n play, therefore, the Onvian dongle is a wasted purchase for them.

This being Bluetooth 4.0, is capable of transferring data at a speed of 3Mbps. It only supports backward compatibility of Bluetooth 3.0 and 2.0, nothing more. Other than that, the Onivian USB adapter works well and will satisfy the wireless needs, alas with no definitive guarantees and customer support.

The point of this dongle is to be the quickest and easiest solution for people wanting to rid themselves of wires. And this does just that, albeit with no flashy features. However, it compensates that with a very low price and reliable performance.
