The Best Bluetooth Car Adapter – Buying Guide

The Best Bluetooth Car Adapter – Buying Guide


From HIFI sound security systems to simply taking calls, Bluetooth adapters can increase the potential of your system that doesn’t have wireless connectivity. If you have a vintage car with a high-quality sound system that doesn’t have wireless connectivity, a Bluetooth adapter can certainly help a lot.

We have picked and chosen a wide range of adapters coming from some of the most reputed brands after careful testing. A good adapter has high-quality sound streaming and clear sound quality during calls. Furthermore, it should be easy to use and should have a great controlling scheme. Some of the high-quality models have voice command support as well which eliminates the need to go for the adapter itself to operate it. This makes them easy to use as well as safer during driving.

While choosing these products we have made sure to consider all the above factors. So without further Ado let us get going.

How we picked and tested

First, we tried to find as many devices as possible that were rated highly by real-time reviews. There are a couple of places that we looked for reviews like CNET and PC mag. But the reviews on those review sites were years old and we needed fresh reviews to shape our opinion. So we poured in some Amazon reviews as well which brought us to new facts. Some of those we presumed because they were so obvious and some of them were tested.

There were a few things we kept in mind while comparing these. Whether these are noise canceling, whether they have a dual microphone for high-quality call quality, what is the quality of Bluetooth or FM connectivity, and how easy were they to use considering the common experience of users. Keeping in mind all those things, we choose the candidates for this list. For finalizing the products for this list we subject them to tests and established the following criteria for them to pass for this list:

Audio quality:

When you purchase a Bluetooth adapter, this is probably the most important factor to consider. If an adapter is loaded with features that may work well but has no sound quality, then there is no point in using it and listening to bad quality music. It is all about the experience so we give this factor the utmost consideration in choosing the products and don’t compromise on it.

Unless you have a crystal clear sound for calls and high-quality music, an adapter is good as a brick. But we focused more on the call quality as these devices are specifically designed to take calls primarily. Secondly, you can use them to play music as well. If you want a true Bluetooth experience, you need both high-quality calls and high-quality music. The products that didn’t have either of those were discarded.

 Ease of use:

You are most likely to use these adapters while driving and putting them inside your car is of no use if you have difficulty in using them. While driving you must focus on the wheels. If a device diverts your attention, it is not safe for you to use during driving. Therefore, we looked for those products that have easy to press and identifiable buttons so that you don’t have to look every time on the adapter when you want to change the music or attend to a call. For that purpose, we tried our best to choose products with voice command support.

 Power source:

Most of the adapters work with the 12v accessory port. But we also kept in mind to choose that transmitter that has at least one USB port for charging so that while you are using the adapter you can also charge it.

 Brand Reputation:

There are over a million sellers on amazon selling more or less the same thing with the same features. There is no associated brand name with many of them or at least no known brand associated with the products. Amazon offers hundreds of those products. So we only chose the products that have a good reputation based on recent customer reviews.

Elimination based on reviews:

Anything that had many bad reviews, we didn’t consider that product for this list. Anything we found to be suspicious or had low reviews, we discarded from this list.

Testing voice quality:

During our actual testing phase, we performed several voice quality tests before writing this guide. To gauge out the voice quality, we tried leaving voicemails to other phones to test how it sounds. We tried first with windows closed and then with windows open to see how good their noise cancellation works. Then we distributed the copies to different people in our team to test out the quality and give their feedback. Based on that feedback only we formed the aggregate and rated the products based on this factor. You will see that some products on this list may not have a lot of features but are still ranked on the top. That is solely because of the reason that our primary control factor was the voice quality above anything else. We followed the same procedure to test out music streaming quality.

Frequently Asked Questions (FAQs)

If you have a HiFi sound system that doesn’t have Bluetooth connectivity then Bluetooth adapters are worth buying as they can increase the potential of your already existing sound system without having to replace it. They are a supplement to your sound system. These kits are useful for use as a hands-free alternative for your system. They allow you to receive and make calls and listen to music wirelessly. You can connect them to various devices like headphones, phones, earphones, and even your home systems if they are in range.

2.  How Do Bluetooth Car Kits Operate?

They might be advanced gadgets but they work in a pretty straightforward way. To understand how these kits work, first, you have to understand that there are many types of Bluetooth adapters and each of them works differently based on its functionality.


These are the kind of adapters that usually don’t have the traditional audio jack. Instead of directly connecting to the jack they use an FM radio signal to connect to the already existing system of your car’s stereo system. To make them work, you have to tune both the adapter and your system to the same frequency. These kits also connect to various other devices like phones, iPods, tablets, and legacy devices like mp3s. These adapters relay each signal to the radio of your car through your phone. For connecting these to your car, the car’s cigarette lighter is used.

Jack operated  adapters

They also come with a docking station that has controls to comfortably use the device. They are powered by connecting them to your car’s lighter port.

Battery-powered transmitters

Other models connect to the stereo or your phone in the same way but they do not need to be plugged in all the time as they have a rechargeable battery that can run continuously for hours.

They can be charged via a USB cable if you have one inside your car or you can use an adapter that plugs into the lighter port to charge your devices.

3.  What Type Of Phones Does Bluetooth Car Adapters Support?

4.  How to Connect Bluetooth Car Kit to a stereo?

There are different ways to connect your adapter to a stereo and it depends on what kind of connectivity your adapter has.

6.  Can A Bluetooth Car Kit Harm The Car’s Battery?

There is a high likelihood that something like this can happen provided that you have turned off your car.

If your car doesn’t do those automatically, just remember to turn off the lighter port every time you switch off your car.

7.  Why do people hear An Echo When I Use The Car Kit?

There is no proper solution to this problem. If you are experiencing eco issues during your calls, then it might be a problem with your car kit and it is time to upgrade. Newer models use ambient noise and echo cancellation technologies to minimize this effect.
