Bluetooth adapter - what is it, how it works, what it is needed for, main types, existing profiles

Bluetooth adapters are modern useful gadgets for creating accessible wireless communication between various devices: tablets, mobile phones, smartphones, laptops, PCs, speaker systems and TVs.
Adapters create a reliable connection for the quick exchange of useful information, files and work commands. Stable and high-speed wireless connection protocol – Bluetooth. The choice of adapter directly depends on the specific tasks it is intended to solve.

What is a Bluetooth adapter?

It is a device that receives a signal via a wired connection and transmits it wirelessly, that is, via Bluetooth. The gadget can be equipped with various inputs and outputs. Thus, many models are equipped with jack or AUX inputs for connecting headphones and can themselves be connected to other devices via a wired connection. Such options are ways not only to transfer music from a smartphone to headphones, but also to connect it, for example, to car radios or any speakers that do not support wireless pairing technology.

Device classification

Experts divide Bluetooth adapters into several classes based on range:

• Class 4 – outdated models, connection range no more than 2-5 meters;
• Class 3 provides a stable signal at a distance of 5-10 meters;
• Class 2 with a connection range of 50 meters;
• Class 1 – these include models that allow you to connect at a distance of 100 meters.

Pros and cons of the connection

The advantages of this method of sound transmission are as follows:

• The absence of connecting wires and docking stations between the sound source and receiver and, as a result, increased comfort when watching movies or playing games on the console.
• Sound quality is no longer dependent on the acoustic characteristics of the room, the quality of the TV speakers and extraneous noise.
• People who are hard of hearing can watch TV without disturbing family members.

The Bluetooth transmitter reduces the sound quality and volume.
The disadvantages of this connection method are the following:

• A decrease in sound quality and volume when the receiver moves away from the source by 10 meters or more or when there are barriers impenetrable to radio waves.
• Limited number of devices connected to the adapter. The more there are, the more expensive it is.
• The sound lags behind the picture due to poor compatibility of the adapter and headphones.

Adapter capabilities

Using this small gadget, depending on its configuration and functionality, you can solve a number of problems:

• Connecting wired headphones to smartphones that do not have a corresponding connector;
• Transferring data from a smartphone to a PC (if Wi-Fi or a wired connection cannot be used for this);
• To connect car radios or speakers that are not equipped with a wireless communication module to a smartphone;
• To connect to a PC another device with a built-in wireless adapter (headphones, a modern printer, and so on).

How to choose a Bluetooth adapter

When choosing, you should pay attention to a number of characteristics:

• Protocol version;
• Supported codecs;
• Housing and connectors;
• Power supply.

Protocol version

When choosing a model, pay attention to the Bluetooth version - the newer it is, the better. The fact is that each new version is characterized by increased signal transmission quality and pairing range. Today, purchasing devices with a version lower than 3.0 does not make sense.

When pairing two devices with different versions of Bluetooth, the signal is transmitted using the low version.

The pairing range depends on the wireless version. For Bluetooth 2.0 and 3.0 it is 10 meters. Bluetooth 4.0 and higher already works at 50 meters or more.

Codecs

Data transmission can be carried out using three codecs:

• A2DP;
• SBC;
• ACC

The first two imply a high degree of compression of the media file during transmission, which will negatively affect the sound quality. For audio playback, the AAC codec is considered the best.

It's also worth considering audio latency when using wireless headphones. When streaming music or watching movies, the lag is automatically compensated, while in cases of computer games, the sound appears unexpectedly and compensation will not be made

Housing and connectors

Adapters are available in different housings. They are usually quite compact in size. They can be made in the form of a keychain or flash drive, made of plastic or metal. The kit may include several cords: for charging and wired connection. Models in the form of a flash drive usually have a USB plug for recharging.

Power supply

When choosing, pay attention to the type of built-in battery and its capacity. Models with lithium-ion and lithium-polymer batteries can be a very good choice. A fairly popular model from the Chinese manufacturer Xiaomi Mi Bluetooth Audio Recevier is equipped with a polymer-type battery with a capacity of 97 mAh, which provides 5-7 hours of continuous operation.

The maximum range of the adapters is 50-60 meters, so they are used in apartments, houses, offices and shops.

This technology is used to quickly exchange audio, video and text files; you can manage RAM, send and receive photos, and manage work programs.

The module is connected without additional cables and adapters, via a standard USB port. The advantage of the module is the ability to transmit data at high speed. The modules are capable of establishing and maintaining wireless communication even with short-term wave interference that occurs between devices.

Can a Bluetooth adapter become a replacement for wireless headphones?

To summarize the article, it is necessary to answer this question. Unfortunately, there is no clear answer.

If the Bluetooth receiver will be used to improve the mood during sports training, or the user is not particularly demanding of quality, then the cheapest of the listed devices will be sufficient.

In the case where the user is a music lover, and minor sound distortion is not acceptable, then it is worth purchasing one of the expensive devices. In this case, the combination of a Bluetooth receiver with wired headphones will be an excellent alternative to full-fledged wireless headphones and will allow you to enjoy high-quality sound.

Best Bluetooth Adapter - Asus BT-400

After weighing the pros and cons of the three Bluetooth adapters mentioned above, the one made by Asus is the best.

It offers a stable and responsive connection, is easy to install and use, and even the design is quite grippy, making it easy to remove from the port. Plus, the device even comes with a detailed manual, which is missing from most cheaper products.

Ultimately, we only recommend purchasing any other dongle if you want to be as budget-friendly as possible, and either of the other two dongles on this list would be a good choice!

Bluetooth USB adapter

Bluetooth USB adapter - designed to connect to a computer or laptop via a wireless connection to a printer, headphones, keyboard or smartphone.

The ultra-compact and lightweight Bluetooth USB adapter allows you to connect to a huge variety of Bluetooth devices and transfer data at speeds of up to 3 Mbps over distances of up to 10, 30 or 50 meters. A wide range and competitive prices will allow you to find and buy a Bluetooth adapter for your computer with a suitable version of Bluetooth 2.0, Bluetooth 3.0 or Bluetooth 4.0.

Bluetooth speaker adapter

Which adapter is suitable for TV

Not all TVs, even those with Smart TV technology, support Bluetooth. Some newer models simply require you to enable the built-in module. But regardless of the type and “age” of the panel, you can always connect an external adapter to it.

Bluetooth modules for TV will help solve sound problems that arise when watching. If it’s too quiet, you can connect a wireless speaker and place it nearby, and in order not to disturb others, connect wireless headphones and watch movies when everyone in the household is already asleep.

Some adapters allow you to transmit sound from a smartphone, tablet or computer to your TV.

Before purchasing a Bluetooth adapter, you need to make sure that the device can connect to your existing TV. Most modern models are equipped with a standard 3.5 mm jack, and some have an RCA output or an optical digital audio output.

adapter is powered via a built-in battery or via an additional connection to a USB port. Modules with a built-in battery are more convenient to take with you, although this is not so important for a TV - after all, the adapter will be located near the display.

Don’t forget about coverage radius : how far is the user from the TV when watching? In the case of a home TV, this point will not be a big problem.

If the Bluetooth module will be used to listen to music from a smartphone, you will probably need a device with a long range and a strong signal that passes through walls and other obstacles. These requirements are met by adapters that support the latest Bluetooth specifications - from 5.0 and later.

If you want to output sound from the TV to multiple speakers or headphones, you need the adapter to support working with multiple devices at once . A significant portion of the models on the market can cope with this task, but before purchasing, it is better to check the availability of this feature.

How to choose a Bluetooth adapter for your car

Modules of this type are connected to the car’s audio system, linking and synchronizing it with the media - that is, a smartphone, tablet or other gadget. Such adapters do not take up much space in the cabin, are convenient to use and increase the safety of the driver and passengers. The user will be able to receive and make calls without being distracted from the road, and music will be transmitted without interference or interruption.

There are many car Bluetooth adapters on the market in different variations, but the most common ones are:

Devices with AUX input

A common and very versatile type. They connect to a 3.5 mm jack, so they can be connected to almost any radio. Adapters of this class are capable of receiving calls and playing audio from a phone or flash drive.

The advantages of AUX models include compactness, signal stability and high sound quality. The disadvantages are higher cost than other types of devices.

FM transmitters

Models of this type use FM radio frequencies into which the audio signal is converted. Such adapters connect to the cigarette lighter, allowing you to receive calls, listen to music and radio.

Among the disadvantages is a more bulky design than that of AUX models, as well as the resulting noise and hiss. The main advantage is the low price. In addition, this is one of the few options for cars without an AUX input.

USB adapters

They resemble a regular flash drive and connect to the USB port of the car radio, becoming another solution if there is no AUX connector.

The strengths of such models are compactness and low price, but the disadvantages are low sound quality and poor signal stability. In addition, not all car radios are compatible with USB adapters, even if they have a corresponding port.

"Visors"

Not as common type as others. Such models are usually more expensive because they are equipped with built-in speakers for hands-free calling. The sound is transmitted through them, and not through the car audio system, so speech and music are reproduced very clearly: without distortion, interference or echo. This type of adapter attaches to the sun visor.

Among the useful points, management . Some devices have LCD displays, while others only have multi-function buttons. Before purchasing an adapter, you need to determine which option will be more convenient for you.

A high-quality model also supports automatic pairing. Thanks to this, you do not need to configure the adapter every time you connect to your devices. The Bluetooth module independently remembers previously connected equipment, and when it is within range of the signal, it pairs with them.

If the user plans to frequently receive calls from the phone in hands-free mode, he will have to look for a Bluetooth module with a microphone and noise reduction . This will help reduce background noise on the road during a call.

When there is often not only the driver, but also several passengers in the cabin, a Bluetooth adapter designed for simultaneous pairing with several devices will be a plus. Otherwise, only one gadget will be able to connect via VT.

Bluetooth headset

A Bluetooth headset is the best option for communication on the road and while driving - your hands are always free and your actions are not constrained by wires.

In NICS you can choose and buy a SONY or Plantronics Bluetooth headset with voice control support and the ability to connect to two phones, with a button to accept/end calls and volume control. When choosing a Bluetooth headset for your phone, pay attention to such characteristics as how it is attached to the ear - whether it will be an in-ear headset or an earhook is up to you to decide. As a rule, Bluetooth headsets, due to their comfortable design, are suitable for wearing on both the right and left ear. Here you will find models of wireless headsets with Smart Sensor technology. This function detects the moment you put on the headset and allows you to answer a call without pressing a key. Bluetooth headsets are comfortable to wear, easy to set up and use. They are charged via USB, and their battery life can last up to 11 hours of listening to music or talking. Attractive prices will allow you to buy a Bluetooth headset for your phone with the optimal version of Bluetooth 3.0, Bluetooth 4.0 or Bluetooth 4.1, as well as NFC support. Listen to music, talk on the phone comfortably and enjoy freedom from wires.

Asus BT-400 Bluetooth Adapter

Asus is the first big and recognizable company name on this list, although it may seem that the brand is the only thing that distinguishes the company's dongle from other cheaper ones on the market.

Once again we have an incredibly small USB adapter that is invisible when plugged into a laptop or the front of a PC. It's also a little easier to remove from the port due to the design.

The dongle includes plug-and-play functionality that's compatible with both Windows 10 and Windows 8, and Asus's provided drivers work correctly with Windows 7, although we weren't able to test the device on XP. Even if you encounter some problems, you can always download the latest drivers from the Asus website, and the adapter itself comes with a detailed manual.

We found virtually no faults with the device, except that it is a little more expensive than others in its category. However, we think it's more than worth it given how well the dongle works and the instructions and support offered by Asus.

Pros:

Stable signal; Good driver support; Plug-and-play functionality with Windows 10 and Windows 8.

Minuses:

A little more expensive than competitors.
