Buyer’s Guide: How to find the Best Bluetooth Adapter

Choosing any equipment requires knowing the features that affects its performances. Bluetooth adapters are mostly USB plug-and-play and fairly easy to use. Nevertheless, to pick the best while sifting through dozens of products, here’s what you need to decide which one is perfect for you.


When picking your Bluetooth adapter, it’s important to know which devices you intend to link. Dongles can connect to almost every Bluetooth peripherals but the bandwidth at which said peripherals operate differs from one to another. Some use a regular bandwidth and others such as mice or keyboards for computers are compatible with a lower frequency. In case you’re wondering: can I use a Bluetooth adapter on my TV? You must know that you should check the adapter’s specifications to see if it will suit your needs.

Range: Class 1 Bluetooth adapter VS. Class 2 Bluetooth adapter

This criterion refers to the maximum range at which you can connect and use a device linked to your Bluetooth adapter. For class 2 adapters, depending on the product, you can get between 30 and 60 feet of range, which is more than enough for a regular use. For those who require a greater range, Class 1 devices designed for industrial peripherals can transmit data up to 330 feet. Although you will see many devices with the same range, you need to assess the efficiency of the transmission. As it is often the case, many devices with the same specifications can perform differently.

Bluetooth Version

Bluetooth technology is constantly improving. But to pick the best adapter, always choose a device with the 4.0 version. It’s faster, less power-consuming, and more importantly it is the most widely used version. If you intend to link peripherals that work on lower versions, you should know that recent versions of Bluetooth have backward compatibility. Your old devices will thus work with your new adapter; although you might have to install some drivers in that case.

Mostly used by new smartphones, Bluetooth 5 is more focused on data transmission in the Internet of Things (IoT). It is faster and allows you to control multiple peripherals from a single device. It is mostly used for Smart homes with multiple appliances such as thermostats, cameras and security systems, or kitchen gadgets. Although more advanced, you should remember that the 4.0 version is still the most used and is more convenient to transmit data between two devices.

Power Consumption

Introduced with the 4.0 version, BLE (Bluetooth Low Energy) is one of the three protocols included in that version. Mainly focused on reducing energy consumption to increase the battery life of devices, it is a must-have if you are looking for the best Bluetooth adapter. When picking your adapter, look for the Bluetooth Smart logo that will indicate the device is compatible with BLE.


You should also check a few additional features to pick the dongle that will best suit your needs. Will you be connecting a smartphone to a computer regularly? Then, you will need an adapter with NFC compatibility. Does your dongle allow automatic pairing? This feature will allow you to use your adapter and linked devices more intuitively. Will you be using Linux or Mac OS? If that’s the case, pick an adapter that is compatible with many operating systems. You will also need an adapter with drivers that are easy to find on the manufacturer site or comes with an installation CD.


Here are answers to some of the questions often asked by people looking to buy the best adapter.

1. How to get the best sound from Bluetooth adapter?

If you’ve experienced poor sound quality with your device, you may try these few steps to solve the issue.

  • Check your device’s tone settings such bass, reverb, treble. Tweaking the settings might help you have a better sound.
  • Move your adapter closer to your sound system as it may be a range issue.
  • Keep the adapter away from other devices that might create interference by generating an electromagnetic field. Common appliances such as your router or your microwave can be the source of the problem.
  • Re-pair your Bluetooth adapter with the multimedia system you want to connect to.
2. How to find the best Bluetooth Adapter?

To find the best device for you, you need to follow the criteria mentioned earlier in the buyer’s guide. Following these tips will not only help you pick a good adapter but will also enable you to choose the most suitable one for your needs.

3. What does Plug and Play mean?

Plug-and-Play refers to Bluetooth adapters that do not require the additional download and installation of files or drivers before use. These kinds of adapters already have preinstalled drivers by the operating system and require no further installation. But in case of older operating systems, additional drivers may be required for smooth operation.

4. What type of data can be transferred via Bluetooth?

A wide range of data types can be transferred via Bluetooth, some of which include audio files, video, pictures, multimedia streams, data transfers and many more.

5. How much power does Bluetooth adapter consume?

If you’re using your Bluetooth adapter with a Smartphone or a laptop, you might be wondering how much power does a Bluetooth adapter exactly use. No one really likes the battery low notification that keeps popping up when listening to music or making a call.

First, you should know that with the BLE protocol integrated with the version 4.0 in 2011, most devices use very little energy while the Bluetooth is on (used actively or on standby). But it mainly depends on what you are doing with your device.

Most adapters use both Bluetooth classic and BLE protocols. If you are listening to music or sharing files between devices, your adapter will switch to the classic protocol. While for IPS or location services, BLE is more practical and will be selected automatically, the differences are mainly in terms of transfer speed and energy consumption.

BLE offers a maximum speed of 200 kbps for data transfer with 0.01 W to 0.25 W energy consumption. On the other hand, the Bluetooth classic protocol offers 2–3 Mbps transfer speed for 1 W of energy consumption on average.

6. What Is Bluetooth 4.0?

Presently Bluetooth 4.0 is the most widely used version of the Bluetooth technology. This specification was released in June 2010 and was immediately adopted and used by smartphone manufacturers the following year. This was primarily due to its low energy requirement, the aim of which was a battery life extension for mobile devices. The two main updates to this specification are 4.1 and 4.2. The first update 4.1 enables communication with 4G LTE devices while the second 4.2 was designed to support IoT devices.

7. Can more than one Bluetooth adapter be used simultaneously?

In order for Bluetooth connection to work perfectly, only a single Bluetooth adapter can be enabled at a time. You are at liberty to install more than one adapter on the same computer but only one must be enabled at a time. The use of multiple adapters at the same time on the same computer can prevent it from utilizing Bluetooth technology. Nonetheless, it is possible to use multiple Bluetooth adapters to pair different devices.

8. What is the procedure for connecting a Bluetooth adapter to a Windows computer?

Are you wondering how to use a Bluetooth adapter for Windows 10? Since most Bluetooth adapters are plug-and-play devices, Windows will immediately recognize the standard interface used by the device and automatically install a driver to enable Bluetooth connectivity as soon as it is plugged in the computer. Any additional steps and installations will be specified by the manufacturer if required, in the case where it’s not a plug-and-play device.

9. What is the procedure for connecting a Bluetooth adapter to Mac OS?

Now that you know how to use a Bluetooth adapter for Windows 10, let’s take a look at how it should be done on Mac OS. Most Apple computers are usually furnished with an inbuilt Bluetooth system which usually gets in the way when you try using third party Bluetooth devices. The first step will be to disable the inbuilt Bluetooth system before installing the adapter in order to enable pairing with other Bluetooth devices. In certain cases, you may have to install developer tools that include a Bluetooth explorer program which is used to select which Bluetooth adapter to enable.

10. What is frequency hopping?

It is a security measure adopted by Bluetooth devices during data transfer. This is achieved by rapidly fluctuating the frequency at which different packets or sections of data are transferred using a pseudo-random sequence only known by the transmitter and the receiver.

11. What type of devices use Bluetooth?

Almost all new devices like smartphones, laptops, tablets and audio speakers are now equipped with standard Bluetooth connectivity. Other devices that also use Bluetooth for data transfer and communication include wireless keyboards and mice, game controllers, televisions and vehicle audio systems. Are you asking yourself “can I use a Bluetooth adapter on my TV?” The answer is yes. Some adapters indeed support TV and Home Stereo.

12. How to use a Bluetooth audio receiver in a car?

If you have the best Bluetooth audio receiver, you may want to use it with your car. You have 2 options to connect your car audio system to a Bluetooth device. You can either use an AUX-connection device or an FM transmitter adapter. The first type connects directly to the 3.5 mm auxiliary jack of your car stereo system, enabling you to make calls and play music wirelessly directly from your phone. As for the second, it is for older cars without an AUX jack but with a 12 V Cigarette Light Plug instead.

Both types of devices are Plug-and-Play and allow you to connect your smartphone in a few seconds to your car system in order to listen to your music, make calls hands-free and use Siri or Cortana. Make sure to pick the best Bluetooth audio receiver for car depending on your car model and the connection options available.

13. What is the best long-range Bluetooth audio receiver?

Whether you are planning to buy a class 1 or a class 2 Bluetooth adapter, you should consider the range carefully. There are a lot of devices that can help you exchange data between devices using Bluetooth. While most BLE devices consume less power, if you are looking for the best long-range adapter, they may not suit your needs. BLE is mostly used for low speed data transfer exchanges. Audio does not fall into the category of low speed data.

It is therefore preferable to pick an adapter that mainly uses Bluetooth classic protocol to increase your speed. Your transfer speed will have a direct influence on the quality of the sound as well as on range. Nevertheless, make sure to free the space between the devices that you connect and your adapter to improve the quality of the data transmissions. These criteria are also important if you are asking yourself “what is the best adapter for home stereo?”

14. How do Bluetooth audio receivers work?

Using a 3.5 mm jacket or a 3.5 mm RCA to connect your phone or laptop to your sound system can be challenging. If you have to do it all the time, not only does it restrict your mobility, but it is also inconvenient. Using a Bluetooth adapter is easier and more practical to enjoy your music on your speakers while walking around. These adapters work as a bridge between your devices, allowing you to share the audio from your phone or laptop (mobile) to your sound system (fixed). Remember to pick you adapter while keeping in mind that it must have a good range and provide high-quality sound at all times.

15. What are Bluetooth drivers?

A Bluetooth driver refers to any software that is designed to allow an operating system to effectively communicate with a Bluetooth device.

Knowing the criteria and most important specifications of Bluetooth adapters, you will now be able to choose the one that’s perfectly tailored to your needs. Remember the best Bluetooth adapter must have a good range, be plug-and-play, have a nice transmission speed and at the very least, use version 4.0 of the Bluetooth technology.

Our pick is the Aventree BTTC-500-W-US. If you’re looking for a Bluetooth car kit to turn your car into your stereo while moving, consider choosing one that is compatible with many devices and offers many different connection options.
