Bluetooth is a technology that is very popular with car owners. In the car, you can use it to communicate via cell phone without holding the phone to your ear (especially since it is forbidden by law). Consequently, communication via Bluetooth still plays an important role in terms of the driver's own safety.

In this post, we have collected 5 Bluetooth adapters that will suit any car.

Anker Roav (under $30)

The Roav from Anker is slightly larger than a standard car charger, provides both a Bluetooth connection to your phone and an FM radio transmitter to your car stereo. By simply plugging the device in and using the Roav app to set up a blank FM station, you can add Bluetooth music streaming and phone calls wirelessly.

If your car has an Aux input, you can connect the Roav directly to it instead of relying on the FM tuner. This also results in clearer calls and less interference when listening to music.

Nulaxy KM30 Bluetooth Car Adapter (under $25)

The Nulaxy KM30 is the best Bluetooth FM transmitter we have seen so far. It offers an impressive combination of features, sound quality, and price. If you are looking for a Bluetooth FM transmitter with no unnecessary features and great quality, this is exactly what you need. The sound quality is adequate but very good for a Bluetooth FM transmitter. It is a bit muddy, so if you expect the sound quality to be the same as a wired connection, you will be disappointed.

How to choose an adapter for a car?

Connecting additional equipment to the car is sometimes difficult. The reason for this is that the connectors can easily be damaged and thereby rendered unusable. Accordingly, the choice of the devices to be connected should be taken seriously. There are several ways in which you can organize the playback of audio files:

  • FM transmitter - a small device that connects to the car player via radio frequency;
  • Using Bluetooth Flash - essentially a flash drive that provides a Bluetooth connection;
  • Via a Bluetooth to AUX adapter.

To avoid damage to your car or its connectors, you need to carefully select the adapter itself. Check if the adapter is compatible with your car and the smartphone you will be connecting to. It is best if it says on the box of the device that it is compatible with your model. If it says "single-platform model," then compatibility conflicts are very real.

Getting a display exclusively in Chinese is fraught with setup problems, so make sure that it supports English (or any other language you know). Check the system's ability to display numbers and other subscriber data. In addition, not all devices support voice dialing. Even if it is in the functions, additionally check whether it is tied to the intonation of the operator's voice.

Bluetooth-based adapters that support AUX are the most popular choice for a car. This is because it has not only a wireless connection but also AUX, which is the analog input of the car stereo. The device can also be powered via a USB connector. So it is good to have such a port in the car itself. Thus, you can connect the adapter through both the cigarette lighter and USB. This connection has quite a lot of advantages:

  • Stable signal;
  • The sound without interruptions;
  • Compactness;
  • High quality of audio;
  • Universality.

All in all, adapters with Bluetooth and AUX are still the best buy if you want to communicate with people wirelessly in the car. Such a connection is superior to other means of voice transmission. For example, an FM transmitter is connected to the cigarette lighter at all times. You won't be able to turn anything else on through it. The simplest transmitters also have a narrow range of radio frequencies. Some radio stations may simply interrupt your connection. Bluetooth Flash is unstable in the transmit signal. Sound suffers the most from this - it disappears or is intermittent. This technology also has a small number of devices that support it.
