Looking for a new Bluetooth adapter for your PC? There’s a wide variety of these devices available today intended for different purposes, ranging from connecting a set of headphones to linking a smartphone to a PC using NFC. In this guide, we’ll cover what bluetooth adapters essentially are, how they work, and things to look for when shopping. We’ve also sifted through the chaff to find the TOP 5 Best Bluetooth Adapters for PCs available in 2018.

Adding wireless peripherals has become inexpensive and convenient, but it often requires you to purchase a more powerful Bluetooth adapter than the one built into most laptops or computers. If you need to connect devices from further away than 30 feet or devices that need more bandwidth, buying a third-party Bluetooth adapter is a solution. It’s also possible to find adapters that convert wired devices like speakers to Bluetooth peripherals.

What You Will Learn from This Guide:

What is a Bluetooth Adapter?

Sometimes also called a “dongle,” a Bluetooth adapter is any device designed to connect to a PC, laptop, or mobile device and provide a Bluetooth connection service. Bluetooth adapters are often small USB plug-and-play devices with nothing more than an antenna for transmitting and receiving data and a few Bluetooth chips. Others are larger devices that sit on a desktop to provide connections to devices that aren’t wireless or give a boost to a connection’s range.

Features to Consider When Shopping for a Bluetooth Adapter

Bluetooth adapters aren’t as complex as they might seem, but there are a few features and considerations you should keep in mind when shopping for one. It isn’t just a matter of finding the best price if you’ll need better performance. Below is a list of the major factors to look at when comparing adapters.

  • Intended use: Bluetooth adapters are not always able to provide a good connection to every type of Bluetooth peripheral. Some are intended for low bandwidth devices like computer mice and keyboards but won’t be able to provide a proper connection for wireless speakers. Check an adapter’s intended use before making a purchase.
  • Maximum range: These adapters also have different effective ranges. If you need a connection's range to go beyond 30 feet, pay attention to the maximum range when comparing adapters. Most will have 30-foot ranges, but some reach as far as 60 feet.
  • Bluetooth version: Bluetooth 4.0 is the standard most devices support, but a Bluetooth 3.0 adapter will work fine if you don’t need to worry about high bandwidth or battery life. Otherwise, stick to Bluetooth 4.0. It’s more efficient and supports faster transfer rates.
  • Other added features: There’s a few other extras that separate some adapters from the pack. NFC compatibility is useful if you want to connect a computer to a smartphone. Automatic pairing mode is another nice feature that makes using Bluetooth devices more intuitive by eliminating the need to manually pair them.

Frequently Asked Questions

What is the Bluetooth 4.0?
Bluetooth 4.0 is currently the most widely adopted version of this technology. The specification was released in June 2010, and the first smartphones to support it began to appear in 2011. The most important improvement in Bluetooth 4.0 was the addition of a low power usage protocol designed to extend the battery life of mobile devices. Bluetooth 4.0 was updated to 4.1 in 2013 and 4.2 in 2014 to keep up with trends in mobile technology.

Can you use more than one Bluetooth adapter?
Only a single Bluetooth adapter can be enabled at a time for Bluetooth connections to work properly. You can install more than one adapter and only have one enabled at a time. You might do this when testing a new adapter or troubleshooting a connection.

How do you connect a Bluetooth adapter to Windows?
Most Bluetooth adapters are plug-and-play devices, meaning that they use a standard interface recognized by Windows. When you plug a USB adapter into a computer port, Windows will automatically detect it and install a driver to enable Bluetooth connectivity. See your adapter’s instructions for any special steps required by its manufacturer. If you already have a Bluetooth adapter enabled, you’ll need to disable it first.

How do you connect a Bluetooth adapter to Mac OS?
Mac computers often come with built-in Bluetooth connectivity, so it’s likely you’ll need to disable it to use a third-party adapter. Beyond this, you may need to go to some lengths to install another adapter and pair it with Bluetooth devices. Some Macs require you to install developer tools that include a Bluetooth Explorer program, which you can use to select which Bluetooth adapter to enable.

What is frequency hopping?
This is a security measure introduced to prevent eavesdropping of data transmitted between a Bluetooth device and its adapter. Essentially, the two devices agree to a pattern of rapid frequency changes that appears random to an outside observer. This breaks up the data into small chunks transmitted on different frequencies and makes it nearly impossible to reassemble if it’s intercepted.

What data can Bluetooth transfer?
Bluetooth connections transfer any type of data that can be transmitted over a wireless connection, including multimedia streams, data transfers, peripheral device data, and more. Adapters do vary in how much bandwidth and fidelity they support, which can make them better suited to specific types of peripheral devices.

What is the best Bluetooth adapter for a PC PS4 controller?
Not all adapters are designed with the bandwidth needed for a game controller, so be sure to get an adapter that’s designed to work with a PS4 controller.

What’s the best way to troubleshoot an unstable connection with a game controller?
Common issues that can contribute to connection problems for game controllers are the distance the controller is from the Bluetooth adapter and local interference. Try sitting closer to the adapter and installing it on the front of your computer instead of the back when troubleshooting a poor connection. Physical obstructions are not typically a problem for Bluetooth connections, but eliminating them will help maintain a stable connection when local interference causes difficulties.

What is the best Bluetooth adapter for PC headphones?
There are many Bluetooth adapters designed specifically for headphones, and there are also adapters that can convert corded headphones or speakers to Bluetooth technology. The Avantree Leaf adapter is an example of a high-performance adapter specifically designed to work with headphones.

Pros and Cons of Bluetooth Adapters for PCs


  • Eliminates the need for cables to maintain a connection between devices, allowing them to be further apart that is usually possible
  • Doesn’t require line of sight to establish a data connection like other short-range wireless technologies
  • Uses very little power, making it a good choice for mobile devices with limited battery life


  • Bluetooth data transfer rates are low compared to other wireless technologies like WiFi
  • Troubleshooting connections can sometimes be frustrating

Pro Tips

Tip #1: “Most pairing problems are caused by the device thinking it’s already connected to another Bluetooth adapter. Try keeping the two devices close together and resetting the Bluetooth on each device when this happens.”

Tip #2: “Built-in Bluetooth adapters on PCs and laptops are usually not intended for use with audio speakers or headphones. Look for adapters designed for audio devices for a high-quality audio experience.”
