A Bluetooth transmitter is a device capable of transmitting digital data. It is based on Bluetooth technology. This transmitter has a Bluetooth transmitter and receiver. Data transmission is therefore wireless. In addition, the intuitive nature of Bluetooth technology makes this equipment very interesting and very useful.

The Bluetooth transmitter is an important gadget and it must absolutely be at home. Before purchasing a Bluetooth audio transmitter and receiver, you should keep in mind the following aspects.

  • Connections
  • Maximum Range
  • Bluetooth version
  • Support of Modern Audio Codecs
  • Multi-Pairing Support
  • Battery Life


Most Bluetooth transmitters have an analog audio connection such as the 3.5 mm AUX jack or the RCA cinch plug. The aux input corresponds to the standard of today’s speakers and headphones. In addition to the analog audio connections, many Bluetooth transmitters also offer a digital-optical connection such as the Toslink socket (S/PDIF socket) or a coaxial input.

Maximum Range

The range of a Bluetooth transmitter is a crucial quality criterion. High-quality Bluetooth transmitters have a range of up to 50 meters and more. Bluetooth has three different classes, which differ in their range and transmission power. A larger range also means more power consumption.

The range of the Bluetooth transmitter is divided into classes just like Bluetooth adapters, the range of Class 1 transmitters reaches up to 330 feet, while the Class 2 offers a height of 33 feet. Class 2 transmitters are the most common on the market and are sufficient for home use.

The maximum range is also reflected in the prices of the transmitters. The range required depends on the desired application. For example, if you want to connect the Bluetooth transmitter to your headphones, a range of more than 15 meters is appropriate.

Support of Modern Audio Codecs

Modern audio codecs include aptx low latency or aptx HD. These audio codecs ensure that the audio signals are transmitted to the receiver device with high quality sound and without delay.

The bandwidth determines the sound quality of the audio signals. Above a bandwidth of 320 Kbit/s one speaks of high quality.

It is important that the playback devices also support the aptX codec. IPhones, for example, only support the AAC codec with a lower bandwidth, while smartphones with Android 8.0 are equipped with the aptX codec.

Multi-Pairing Support

For example, if you want to connect the Bluetooth transmitter to multiple speakers at the same time, make sure that the Bluetooth transmitter allows you to connect to multiple devices at the same time before purchasing.

Always choose a Bluetooth transmitter that can be easily paired with the devices. It must have plug-and-play-play functionality. Most of the time, it takes a minute or a second to pair your devices. Configuration and connection may take longer on devices that need to be charged before use. You should work with different Bluetooth devices such as mice, headsets, printers, projectors, televisions, speakers, tablets, smartphones, etc.

In most cases, the Bluetooth transmitter can only be connected to a maximum of two devices; transmitters in the low price segment generally do not have this function.

Battery Life

Battery life plays a crucial role in a Bluetooth transmitter. High quality Bluetooth transmitters have a battery life of up to eight hours. The charging time can take several hours.

In most cases, a USB interface is integrated in the Bluetooth transmitter, so that it can be conveniently charged using a USB cable, even while on the move, using a power bank.

Weight and Design

A light and small transmitter is easy to move. You can use the device elsewhere, but make sure it has the built-in battery functionality. The design must be compact. Elegant and solid is a better choice. Most of the devices on our list are of this type, although few are configured and forgotten.


Finally, the price you should want to consider. The economical Bluetooth transmitter may be able to do the job, but not for longer use. Before buying, read the criteria carefully and choose what suits you. This could save you frustration and your wallet later.


A Bluetooth transmitter allows you to retrofit older sound devices such as your iPod or your old stereo system with the latest Bluetooth technology. The transmitter can transmit audio signals between two devices.

With the help of the Bluetooth transmitter, your TV can also send the audio sound to your headphones via Bluetooth. You can also watch TV in the future while your partner can work undisturbed in the living room.


  1. The Bluetooth transmitter is connected to the audio source either with a 2.5 mm or 3.5 mm jack plug (e.g. AUX) or with a digital optical connection (e.g. Toslink) using an audio cable.
  2. The input enables data transmission. The Bluetooth transmitter finally encodes the data. The data size is reduced so that the data can be transmitted via Bluetooth.
  3. Finally, these are transmitted losslessly to the receiver device and in turn, decoded in the latter. After the conversion into an analog signal, the terminal can play the audio signal.


Before you buy, you should ask yourself what you need the Bluetooth transmitter for. The decisive factor is which device the Bluetooth transmitter should be used for. If, for example, it is used in the living room for the television or the stereo, a stationary application with a power supply is advantageous.

You can also buy a dual adapter. It is both a Bluetooth transmitter and a Bluetooth receiver. The application can both send and receive audio signals and thus offers a more extensive function.


A Bluetooth transmitter is often the cheaper alternative to a device with an integrated Bluetooth function. You can get Bluetooth transmitters at a low purchase price of 15 dollars. The price range is between 15 and 200 dollars. The average price is around 30 dollars.

Expensive does not mean good quality at the same time. Search for comparisons and tests of the products in order to buy the Bluetooth transmitter with the best price-performance ratio.


In order to clarify in advance whether a Bluetooth transmitter is the right one for your desired application, we would like to show you below what alternatives there are for the Bluetooth transmitter.

Audio cable

With short distances between the devices, the conventional audio cable is still recommended. Problems such as background noise generally do not occur here, so that good sound quality can be guaranteed. However, if you want to put an end to the tangle of cables, the audio cable is probably not a suitable alternative for you.

Audio devices with Bluetooth function

Stereo systems, televisions, notebooks, smartphones, etc. in today’s market have already integrated the Bluetooth function in the device. However, devices with an integrated Bluetooth function are usually more expensive and who wants to replace their classic stereo system with a turntable, which has served well for years, with a modern system?

WLAN Adapter

The WLAN adapter is a good alternative to the Bluetooth transmitter. It allows larger amounts of data to be sent without loss. The range of a WLAN adapter is also significantly higher than that of a Bluetooth transmitter. The great advantage for the Bluetooth transmitter is that it can be used anytime and anywhere and does not require a WLAN connection.

TV Bluetooth Transmitter Importance?

With a Bluetooth transmitter for TV or PC, the focus is on sound quality and avoiding background noise. It is important that there is no time delay in the transmission of the audio signal, so that lip synchronism can be guaranteed.

In order to meet these requirements, the Bluetooth transmitter should be equipped with the latest Bluetooth version and support the modern audio codec aptX.

The range, on the other hand, is not important for this application, since you are usually only a few meters away from the television or PC. Most televisions or computers have an audio connection for headphones, which is why the analog connection for the transmitter is sufficient.

Stereo System Bluetooth Transmitter Importance

The Bluetooth transmitter for a stereo system usually has a long range. For example, if you pair your headphones with the Bluetooth transmitter, a connection should also be guaranteed over several meters in order to be able to hear the music in other rooms.

It is also advantageous if the Bluetooth transmitter can be coupled to multiple devices, so that audio signals can be sent to multiple speakers at different locations, for example. In most cases, an AUX connection is sufficient.

The support of modern audio codecs is less important in this application because a time delay is usually not noticeable. An integrated rechargeable battery or batteries is not necessary since the power supply can be ensured by the USB connection to the stereo system.

MP3 Bluetooth Transmitter Importance

Mobility is the most important aspect of the Bluetooth transmitter for the MP3 player. The transmitter should have an integrated rechargeable battery or batteries and, in the best case, also have a USB port.

A long battery life is an advantage if you use your MP3 player frequently on the go. In addition, the Bluetooth transmitter should ensure a long range, so that the MP3 player can also be used at home with the Bluetooth-enabled headphones.

Here too, the audio codec aptX does not necessarily have to be installed in the transmitter, since the time delay does not interfere with the audio sound. A conventional audio connection like AUX is sufficient for this application.

HOW DO I CHARGE A BLUETOOTH TRANSMITTER? Most Bluetooth transmitters have a power supply or a USB port that is connected to the audio source. In these cases, you do not need to charge the Bluetooth transmitter.

On the other hand, if the Bluetooth transmitter has an integrated battery or batteries, charging is necessary. The battery can usually be charged using a micro USB cable or a power supply cable. Batteries can be replaced.


In order to connect two devices such as the TV and Bluetooth-compatible headphones, the Bluetooth transmitter must first be connected to the TV using a jack cable at the AUX input. In addition, the power supply can be ensured by a USB cable or a power supply cable.

After the Bluetooth transmitter has been switched on and the Bluetooth function activated on the headphones, the connection is usually made automatically. The headphones now reproduce the audio signal from the television.


There are many causes for noise. Below we show our four essential tips to avoid noise.

  1. First and foremost, you should make sure that other Bluetooth-enabled devices in the room or in the vicinity are switched off.
  2. You should always place the Bluetooth transmitter as freely as possible in the room so that there are no obstacles when sending the audio signal. Reinforced concrete and metal objects, for example, dampen radio waves.
  3. You should also reduce the distance to the Bluetooth transmitter in the event of noise and interference. The permitted distance depends on the properties of your Bluetooth transmitter.
  4. When adjusting the volume, you should make sure that the volume on the audio source is always set as high as possible. The volume should only be adjusted on the player to guarantee good sound quality.


With a Bluetooth transmitter for the car one speaks of a Bluetooth FM transmitter. These are small FM transmitters with a short range. The Bluetooth FM transmitters often have a pin for the cigarette lighter to ensure the power supply.


If you are considering a high value Bluetooth audio transmitter, be sure to read the aspects of the buyer’s guide mentioned above. If you are planning a portable transmitter, make sure it has a built-in battery that provides a decent life. The protocol version of Bluetooth is also essential to ensure that it is version 4.0 or higher; this will provide a considerably faster transfer rate and a wider signal range.

There are basically thousands of Bluetooth transmitters on the market, if you want to land on the best Bluetooth audio transmitter, take a look at the features you need, narrow down your list and then take action.
