Buying Guide for the Best Bluetooth Transmitter for Cars

So far, we have discussed so many good Bluetooth Transmitter options, as you can see in the above-mentioned list. Although if you are not able to decide which of these Bluetooth Transmitters will be perfect for you, we will help you out.

In this detailed buying guide, we will mention all the facts and features that should be there is a Bluetooth Transmitter. Hence, if you want to pick the best option for yourself, we suggest you read this simple buying guide until the end as it will be a lot helpful for you to make the final decision about the purchase.

Bluetooth Version

In the Bluetooth Transmitters that are available these days, you will mostly find them equipped with Bluetooth 5.0, which is the latest version available currently for car devices. However, there are still some brands that use the older version, such as Bluetooth 4.2, which is not that great as compared to v5.0. The Bluetooth v5.0 offers better connection stability, higher data transfer rates, and has an overall better coverage area also. So, picking the option that uses Bluetooth v5.0 will be a decent choice.

Audio Inputs

Although you will be using Bluetooth most of the time to listen to music in your car. If you have stored your favorite music playlist in a USB drive or a TF micro SD card, you should look for an option that supports such audio inputs as well. Apart from that, there are plenty of good options available on our list that even come with an AUX port so that you can directly connect your smartphone or mp3 player with the device and listen to your favorite songs. The AUX input is also useful in situations like when your friends sitting in the car want to play their own songs; they can directly connect with the device using the AUX cable.

Supported Music Formats

In case you are going to use a USB drive or a TF card to play songs in your car using this device, you should know what music formats are supported by the device. Although the most commonly used music formats like WMA, MP3, are supported by almost every Bluetooth Transmitter device. However, not all of them have the support for higher quality formats like FLAC. Hence, if you generally use FLAC format music files, you have to check the supported music formats before buying the Bluetooth Transmitter for the car.

Calling Features

With these Bluetooth Transmitter devices, you get really advanced features that are present in almost all the latest car models. One of them is Hands-free calling which is possible as you connect your smartphone with the car using Bluetooth. Most Bluetooth Transmitters come with in-built microphones as well that allows you to receive calls without needing to take out your phone and receive the call.

However, the quality of the call is a major concern here also. For that, you should check if the Bluetooth Transmitter has the noise-cancellation CVC technology or not. Basically, the CVC technology cuts all the ambient noises from the environment and amplifies your voice to provide an overall better calling quality at both ends.

FM support

Apart from features like Bluetooth that allow you to play your own favorite music, Bluetooth Transmitters are also capable of playing FM channels as well. While some of the Bluetooth Transmitters have channel presets, some of them also allow you to cycle through the FM Channels and find your most favorite channel by yourself.

Charging Ports

As you might already know that the Bluetooth Transmitters take power from the 12V charging socket that’s present in all cars. However, by installing the Bluetooth Transmitter in the charging socket, you can’t use a mobile charger in the same socket at the same time. That is why most Bluetooth Transmitters come equipped with several charging ports as well. But, not all of them have the same type of charging ports.

A single transmitter can have multiple charging ports such as a 1A port, 2A port, or a 3A port. As of today, most of us have devices that support fast charging, so picking the option that supports Quick Charge 3.0 ports is always a better choice. However, if your device supports a 2A charger only, then you should pick the right one accordingly.


Last but not the least, we always suggest you pick the product that comes with a warranty. Although the products that we have mentioned are all of decent quality. Still, if a warranty is there, the customer has some peace of mind. There are several brands on this list that offer products covered under 1-year long warranty, so you can check that and pick the right one for yourself.


That’s it, these were some of the best Bluetooth Transmitters for cars that are currently available out there to purchase. With the help of the list and the buying guide, you should not be facing any difficulties picking the best option according to your budget and needs.

A quick tip from our side is that look for the option that provides you with all the latest technologies. This way, you will be easily able to find the best Bluetooth Transmitter to install in your car. In case you are interested to know our top picks from the list, here are a few recommendations from our side for you all:
