The best Bluetooth FM transmitter is the upgraded Nulaxy Bluetooth Transmitter with additional functions such as sleep or wake mode and three different music playing modes from Bluetooth, TF Card and USB.

The Comsoon FM transmitter is lacking an AUX port and TF Card port however it has two USB ports that I find slightly odd. Nonetheless, the smartphone calling and controls are located on the side of the device.

Bluetooth FM Transmitter Buying Guide

Listening to the radio and music that you simply do not want to hear can become very mundane. With a cheap FM transmitter, you can switch to music streaming of your own music without any wires or complicated setup.

The majority of wireless FM transmitters are cheap to buy and some even come with warranty. You will usually pay additional if you want the hands free calling but 9 times out of 10 it is included within the package.

Music Streaming

The main purpose of the FM transmitter is to tune into an unused radio station and match it to your device. This is the way music is played through the cars speakers but the quality can be varied across devices.

If you have just purchased car speakers for sound quality but you have a cheap FM transmitter, it may output distorted music. Paying the small amount extra for a powerful FM transmitter such as the Nulaxy is worth the extra.

Hot Key Buttons

The buttons on the Bluetooth FM transmitter can make a world of difference when trying to use the device. The Nulaxy has huge buttons that allow you to switch between songs and answer calls but without this you will need to use your phone.

This can become an issue because you may need to unlock the device and more, which will distract you from driving.

Power Source

The majority of Bluetooth FM transmitters will run from a 12V cigarette lighter. For those that drive older cars and notice that the transmitter is not working, be sure to check the fuse that powers the cigarette lighter. From our research, this seems to be a common issue and not a faulty transmitter.

If the fuse is working, check the continuity using a car electric multimeter to see if there is any current running to the cigarette lighter.
