What is a bluetooth adapter?

Bluetooth adapter

First of all, we'd like to briefly explain what Bluetooth really is: While data was only transmitted via power cables until the 1980s, Bluetooth passed data over the radio. It saves a lot of cable clutter and you are much more mobile with your device. As the name suggests, the adapter brings together two things that cannot work together. A Bluetooth adapter is a small and handy device that always connects previously incompatible transmitters and receivers. For example, you can connect a new headset to your Xbox One or connect an old Hi-Fi audio device to USB headphones.

Likewise, you can use Bluetooth adapters for devices such as computer mice, keyboards, microphones, speakers, headphones, headsets, and even smartphones. With a Bluetooth adapter, you can also turn your notebook, laptop or PC into a Bluetooth receiver. With an adapter, you can, for example, use a Bluetooth mouse wirelessly, flexibly manage Bluetooth speakers without the hassle of connecting cables or connecting Bluetooth headphones to your PC. Even if Bluetooth adapters only come as small plugs, they are capable of great things. And that's what's special. You can take the adapter with you anywhere and connect it easily.

Bluetooth transmitters are now very reliable when it comes to sending data and there are almost no errors or disconnections. On average, Bluetooth adapters reach a range of up to 10 meters. It allows you to use a Bluetooth adapter, also known as a Bluetooth dongle, in a mobile and flexible manner. Make all your devices Bluetooth-enabled with a Bluetooth adapter. The only requirement is that they have a USB port.

Where did the term Bluetooth come from? The name Bluetooth comes from the Danish Viking King Harald "Blauzahn" Gormsson, who was said to have great communication skills. Bluetooth was originally a code name for the newly developed standard. The inventors then decided to use it as a brand name as well.

What Bluetooth versions are there?

Bluetooth adapter

Bluetooth has been around for 30 years and has continued to evolve since then. Over time, new versions keep coming to the market. The first version was Bluetooth 1.0 with a maximum data rate of 1 megabit per second. Then came Bluetooth 2.0. The maximum data rate is 2.1 megabits per second. Bluetooth 2.0 is also the first version to receive additional EDR for Enhanced Data Rate. That said that data rates have increased. Of course, Bluetooth 2.0 is compatible with the first version 1.0.

Bluetooth 3.0 soon followed, which at 24 megabits per second had significantly higher data rates than Bluetooth 2.0. In addition, high speed support is now provided by WLAN and UWB channels. With Bluetooth 4.0, the low energy consumption aspect is added to the extremely high data rates. Connection establishment is faster and security is also enhanced with 128-bit AES encryption. Versions 4.1, 4.2, 5.0 and 5.1 followed, whose data transmission speed and security were continuously improved. Most newer and very recent versions of Bluetooth are compatible with older Bluetooth standards.

Latest version: Starting with the Bluetooth 5.0 version, which has been available since 2016, the range has been quadrupled and data rates have been doubled. Additionally, location determination is added as a service.

What is the difference between Bluetooth and WLAN and what are the advantages and disadvantages?

In contrast to Bluetooth, WLANs are intended for networks with many participants, offering fast connections and, with the appropriate router, also much greater range than Bluetooth. Bluetooth is suitable for short distance data transmission, although data transmission is not as fast as WLAN. Therefore Bluetooth is ideal for devices that require only a small bandwidth. It is ideal for streaming music or making calls using a headset. In addition, Bluetooth is also energy efficient and cost effective.

  • No need router
  • Low energy consumption
  • Inexpensive
  • Maybe without driver installation
  • Stable connection
  • Limited range
  • Low bandwidth
  • The number of network participants is limited
What types of Bluetooth adapters are there?

Bluetooth adapter

There are two types of Bluetooth adapters:
  • USB bluetooth dongle
  • Bluetooth Audio Adapter (AUX)
Below we explain the difference between these two types.

USB bluetooth dongle

A Bluetooth dongle is a Bluetooth adapter that you plug into a USB port and that supplies your computer with Bluetooth. It allows you to use keyboards, mice, headsets, printers, game controllers, and other wireless accessories with your PC. You can also use a USB Bluetooth dongle to transfer data such as music or videos from your smartphone to the source device and play it completely wirelessly. A Bluetooth dongle looks like a USB stick. The nano adapter, which fits in every trouser pocket, is very practical. The Bluetooth dongle draws its energy directly from the connected device via the USB interface. Therefore, an additional charging cable is not required.

  • Wireless sending and receiving of all types of data
  • No additional power supply required
  • Connection and use of multiple devices can be done simultaneously
  • Inexpensive
  • USB port permanently occupied
  • Must be compatible with the operating system used
  • Additional driver installation may be required
Bluetooth Audio Adapter (AUX)

You can only transfer audio data with a Bluetooth audio adapter. This gives you the option to send and play music from your smartphone or tablet to your hi-fi system or car radio. You can connect a Bluetooth audio adapter using a cable or a 3.5-millimeter jack jack. This is the connector found in most audio equipment. The Bluetooth audio adapter cannot charge from the device it is connected to. Therefore, you still need an additional port for charging.

A suitable charging cable is included with most Bluetooth audio adapters. They are often charged like a smartphone via the micro USB in the USB port. You can continue to use the adapter while charging. Please note, however, that the USB port is only used for charging and not for using the adapter. Only USB Bluetooth adapter can charge and work via USB interface.

What does the AUX port actually mean? AUX stands for the English word "auxiliary", which means "extra" in German. Therefore, the AUX input is a secondary or auxiliary input.

With a Bluetooth audio adapter, a distinction is also made between a Bluetooth transmitter and a Bluetooth receiver. In the following sections of our guide, we explain the differences and which type of adapter is best for you.

What is a Bluetooth transmitter and Bluetooth receiver?

Bluetooth transmitter sends data, Bluetooth receiver receives it. Before you buy a Bluetooth audio adapter, consider whether you only need a Bluetooth transmitter, a Bluetooth receiver, or even an adapter that can do both. If you're now wondering what purpose each type of adapter serves, we'd be happy to give you two examples here:
  1. A Bluetooth transmitter is required if you want to use wireless Bluetooth headphones for your TV, for example. To listen to video sound through headphones, all you have to do is connect a Bluetooth audio transmitter to the 3.5mm audio jack on your TV and connect the transmitter to the headphones according to the instructions, which are referred to in technical terms pairing.
  2. You need a Bluetooth receiver if, for example, you want to play music from your phone or smartphone on your hi-fi system. All you need is a Bluetooth receiver, as tablets and smartphones usually have Bluetooth. Your music system speakers receive audio signals from your Bluetooth enabled device via an adapter.
2-in-1 adapters: There are also many Bluetooth audio adapters that can function as both a transmitter and a receiver. This is often referred to as a 2-in-1 audio Bluetooth adapter. However, the adapter cannot send and receive at the same time. To switch between send and receive, you must either unplug the adapter from the interface and reconnect it, or change the send and receive mode using the switch.

How much does a Bluetooth adapter cost?

Since Bluetooth chips are pre-installed in many PCs, mobile devices, and loudspeakers, USB Bluetooth adapters are not very expensive. Prices range from 8 to $12. Buying a Bluetooth audio adapter, on the other hand, is associated with somewhat higher costs. The background to this is that wireless music streaming is becoming more and more popular. These adapters are still affordable at 15 to $30 for the cheapest models. 2-in-1 adapters are available starting at $30. If you appreciate the elegant design and special added functionality, you'll also find top models from $45 in stores.

Where can you buy a Bluetooth adapter?

You can find a simple USB Bluetooth adapter at electronics stores. If you're looking for a Bluetooth audio adapter, it's a good idea to go online, as this type of adapter is hardly available or not available at all in mainstream electronics stores. You will also find a large selection of Bluetooth adapters on the Internet and can compare them in the comfort of your own home.

Which purchasing criteria should you pay special attention to when choosing a Bluetooth adapter?

Bluetooth adapter

To find a high-quality Bluetooth adapter that meets your needs 100 percent, you have to compare different models with each other. In the following sections, you will find out which criteria to pay attention to, what these are all about and what you should pay special attention to in individual points:
  • Bluetooth Version
  • Suitability
  • Install
  • Connectivity
  • Reach
  • Power and battery performance
  • Measure and weight
  • Multi-pair function
  • Loudspeaker
  • NFC Function
  • aptX codec support
Bluetooth Version

Modern Bluetooth adapters include models from version 4.0. They offer the required energy efficiency as well as speed and security in data transmission. The highest security standards and the fastest data transfers are achieved with Bluetooth 5.1. However, this Bluetooth version carries more weight in terms of price. As a rule, a Bluetooth adapter from version 4.0 is sufficient. Please note, however, that not all newer Bluetooth standards are automatically compatible with older versions.


You just need to make sure that the Bluetooth adapter is compatible with the device you are using the USB Bluetooth adapter with. Bluetooth audio adapter compatibility is more dependent on the connection. If the connectors fit, all is well and you can work with the adapter. A USB Bluetooth adapter, on the other hand, must be compatible with the operating system you are using. As a rule, all USB Bluetooth adapters are suitable for all common versions of Windows. If you are working with Linus and Mac, you will have to look carefully to see which USB Bluetooth adapter also supports this system.


If you choose a Bluetooth adapter with Plug & Play functionality, you do not need to install a driver, as the adapter is then tuned to an operating system that is explicitly mentioned by the manufacturer as a compatible system in its product description. Especially if you're not very tech savvy, Plug & Play is the easiest and fastest way to establish a Bluetooth connection. Non-Plug and Play USB Bluetooth adapters come with a driver CD or download link. Driver installation is usually not complicated.


The connection that came with your audio device and that of the Bluetooth audio adapter is a very important criterion in our buying guide. If you want to purchase a USB Bluetooth dongle, it must be compatible with the operating system of your PC or laptop. You don't have to worry about the existing interface.


A range of 10 meters is usually sufficient. It is Bluetooth class II compliant, which provides a range of 10 to 50 meters. If you need a longer range for various reasons, a Class I Bluetooth adapter offers a range of up to 100 meters. Class III Bluetooth adapters have the shortest range. Only 1 to 10 meters are covered here. For range, you have to consider whether the devices you want to use via Bluetooth are in the same room or on different floors, whether there are thick reinforced concrete walls in between and whether your living room has a very large diameter.

Power and battery performance

One of the advantages of a Bluetooth adapter is that you don't need any cables. The USB Bluetooth adapter even works completely wirelessly. For a Bluetooth audio adapter, on the other hand, you need an additional connection for a permanent power supply. However, some cellular models run on batteries and only need to be connected for charging.

Before buying, you need to find out if the Bluetooth adapter in question is compatible with the device you want to supply with Bluetooth in terms of power supply. If your audio device has a USB port near the audio interface, you can charge the Bluetooth audio adapter via USB while it is in use and no longer rely on battery life. If battery life is an important criterion for you, we recommend a minimum duration of 7 hours.

Measure and weight

If you're looking for a USB Bluetooth adapter, size and weight definitely play an important role too. After all, you want to be flexible with the dongle and, if necessary, be able to quickly slip it into your pocket. Therefore, almost all USB Bluetooth dongles are very light and compact these days. They are called nano USB adapters. But many Bluetooth audio adapters can also print with their small size and light weight. The larger model is actually just one of the stationary audio Bluetooth adapters. Some models can reach a length of 5 to 7 centimeters.

Multi-pair function

Thanks to this feature, you can connect multiple devices to the Bluetooth adapter at the same time. This way, you can quickly switch between multiple output devices such as smartphones or tablets without having to constantly pair them with a Bluetooth adapter. The multipair function is very handy if several people in the same household want to use Bluetooth with different devices.


With a Bluetooth adapter, you can not only listen to music wirelessly, but also make hands-free calls in the car. If you are looking for a Bluetooth adapter for your car radio, you should choose a model that also has an integrated handsfree system. You provide an adapter with power via USB on your cigarette lighter as usual.

NFC Function

The abbreviation NFC means "Near Field Communication". This allows your Bluetooth enabled devices to communicate wirelessly with each other by simply touching each other. This is the same process as making a cashless payment using a smartphone or bank card that has NFC. However, buying a Bluetooth adapter with NFC functionality is only useful if both devices you want to connect have an NFC chip. Before buying, make sure your smartphone actually has an NFC chip.

aptX codec support

Since this feature improves audio quality, it is found in many Bluetooth audio adapters. The A2DP Bluetooth profile usually offers the SBC audio codec. This encoding of audio signals is associated with acoustic loss as audio files such as MP3s are converted and compressed again before being sent to the receiver. This process is slow and energy consuming, and somewhat degrades the sonic quality of the audio file you end up hearing.

With the aptX codec, the audio signal is compressed in the same way, but the quality is not reduced compared to the original track during decompression.
