How we picked the best products for this article

We have taken you through the best Bluetooth receivers on the market. Now, let’s share a few hints on how and what to consider when picking out the ideal Bluetooth receiver for your car. They are the same features we based on to bring your our list.


A Bluetooth receiver does not need to have a wide range because you will be near it most of the time. However, in preparation for when you go out for a picnic and need your car to play some music, you will need a Bluetooth receiver with a good range of about 30 feet. 


After you confirm that the device you are looking at has the correct range for you, you also want to look at compatibility. The Bluetooth receiver you choose should be compatible with your car’s inbuilt stereo system. Working with a good Bluetooth receiver should be a matter of plugging and playing.


Since you are using the Bluetooth receiver to listen to music or pick calls, you need the audio quality to be good at the very least. The device’s technology will largely determine how well the sounds play out.

The most common codecs today are aptX, aptX HD, and aptX Low Latency or aptX LL. Amongst them, the aptX LL is the best. Look for devices with low latency because there will be a minimal delay or lag with the sound.

Check for which Bluetooth version the device has. The most up-to-date Bluetooth version is Bluetooth 5.0. Its technology is the most advanced, which translates into a quicker response time, connectivity, and very minimal lag.


The last factor you should consider is the battery life. This consideration is because most devices can operate for about 10 to 15 hours continuously. Although some may not come with built-in batteries, most will come with the option of charging while playing. These are the best because they will not have any delays when the battery is low or not fully charged.


Many cars are manufactured without Bluetooth connectivity in their stereos, while vehicles with a Bluetooth provision usually have outdated Bluetooth technology. Both scenarios can be very inconvenient. Therefore, one may need a car Bluetooth receiver to help them get the best sound to enjoy music from their phone and phone calls when out on drives or picnics.
