A personal FM transmitter is a low power FM transmitter that allows you to take the signal from a portable audio device, cell phone, or tablet, and transmit it to your FM radio.

Best Car FM Transmitter Buying Guide – What to Look for When Shopping for a Wireless or Low Power FM Transmitter

You’re heading to an important meeting you’re almost late for. Luckily enough, the traffic isn’t heavy. As you near the intersection, a call you’ve been expecting comes in. Just then, your smartphone signals “battery low” for the third time. You move to reject the call and, as you look back up to the road, it’s too late. You’ve already run the traffic light. To quickly get out of the intersection, you increase your speed amid several screeching tires.

You make it through unscathed and pull over to catch your breath. After you’ve gathered yourself to continue your journey, you hear a knock on the window. It’s the traffic cop, enquiring if you’re all right and, with a sigh of relief and a smile, you affirm you’re okay. But, he saw you run the red light and almost cause an accident, so he has to process you for a ticket. Now, you’re going to be late for that meeting.

You could have answered the call while driving, hands-free of course, while simultaneously charging your device, if you had an FM transmitter in your car. This would have spared you the dangerous event that led to your ticket. FM transmitters are often wireless devices that let you answer calls via the speakers of your car.

The best FM transmitters have a wide frequency spectrum. They easily pair with Bluetooth-enabled devices and remember them. They can also play audio from your compact flash cards and flash drives. FM transmitters are compatible with many devices that have Bluetooth connectivity. As you read on, you will get more information that will guide you toward choosing the best FM transmitter for your needs.

The amount of technology used in creating an FM transmitter is the primary factor that affects pricing. An FM transmitter with all the bells and whistles can cost around $40, while an alternative with fewer features might go for less than $15. The cheap FM transmitters are the types you don’t even want to think about, let alone buy them. We haven’t bothered with them either, as we believe only top-quality products should make it to our page.


FM transmitters are affordable and easy ways to listen to your favorite music and audio in your vehicle. They also perform other practical functions you will get valuable benefits from. The following are features you should look out for if you plan on getting one:

  • Type
  • Range
  • Spectrum
  • Compatibility
  • Connectivity
  • Usage

The following sections will further enlighten you on how these features affect the performance of FM transmitters.

Construction and Design

Auto FM transmitters are a great add-on to any vehicle. They can be wired or wireless, but nowadays, the wireless versions are almost the only types you will find. The popularity of Bluetooth technology is largely responsible for this, and it is the connection protocol mostly adopted in these auto devices. However, many FM transmitters can also connect to the car stereo via AUX cable.

The quality of the transmission you get is largely dependent on the range of your transmitter. Since you’ll be using it in your car, the range of the transmitter you get should be sufficient. Most transmitters have a range of between 10 and 30 feet, which is more than enough for good reception for your devices within your car.

You might want to choose an FM transmitter with a wide spectrum. This is because you need to tune to an unused frequency to stream audio from your device; the wider the spectrum, the higher your chances of finding an unused frequency. If you’re tuned to a used frequency or a free one that is close to an occupied one, you will have signal interference and noise. So, to get a clear audio signal, you should use a free frequency. Preferably, get an FM transmitter with the whole frequency spectrum.

Performance and Ease of Use

Most FM transmitters are wireless – kudos to Bluetooth technology for saving us from those ugly wires. Bluetooth technology does not only make it convenient to connect; it also facilitates superior audio quality. Since Bluetooth is the most common type of connectivity for FM transmitters, they are equipped with the Advanced Audio Distributed Profile (A2DP), which lets them produce stereo-sound quality. As long as the transmitter is Bluetooth enabled, you are assured it is fitted with A2DP.

The FM transmitters available nowadays are compatible with most devices across most brands. Most of them are fully compatible as long as your device is Bluetooth compliant. They are all designed to fit into your vehicle’s 12V cigarette lighter port, where it gets power from. Pairing your devices with the FM transmitter will allow you to enjoy the benefits the transmitter has to offer.

How you use these audio devices and what they are capable of varies from one brand to another. Once you’re done setting it up by pairing, you can answer calls hands-free, using the built-in mic on the device, and you hear feedback through your car speakers. You can also follow your favorite radio stations by tuning into them with these transmitters – that’s where they got their name from in the first place. You can play music from your phones and MP3 players, and some transmitters support playing from TF cards and flash drives.

One awesome feature some FM transmitters have is the ability to charge your devices via a built-in USB charging port (and some even come with more than one port). Talk about juicing up your devices on the go! Some audio kits have back-lit displays that show information about songs or the station you’re tuned to, just like the Radio Data System fitted with your vehicle’s stereo. It is even common to find some with sound equalizer functionality. Great audio quality is imperative for audio devices, so most FM transmitters have noise filters that maximize sound quality.

This information is aimed at letting you know how these features affect the performance of FM transmitters. This will, in turn, guide your decision on which features are critical to you, depending on how you want to use it.

FM Transmitter FAQs

How does an FM transmitter work?
An FM transmitter connects an audio signal from a device (such as a smartphone) to the car FM receiver. It acts as an extension to help you amplify audio from your phone through the car stereo system of another kind of sound system. So, your phone connects to the transmitter wirelessly via Bluetooth; the FM transmitter converts acoustics from the phone into an FM signal. You can then connect to it by tuning the FM receiver to an unused frequency.
Where to buy an FM transmitter?
You can buy an FM transmitter from Amazon, the largest online retailer. This site has not only the widest variety of products but also the best deals. If you are looking for an FM transmitter to buy, we have reviewed some of the best.
How to use an FM transmitter?
You can use an FM transmitter by first programming the car stereo. After powering the car stereo, turn down the volume, and select the FM function. Pick an FM frequency from 88.1 to 107.9 and make sure no station is using it. To install the FM transmitter, turn the frequency dial and select the frequency on the car stereo. After plugging in the transmitter, wait for it to display the frequency you had set. Start playing audio files on your phone, ensuring the equalizer and bass boost functions are turned off. Rotate your stereo receiver’s FM antenna to get the best possible reception.
What is the best station for my FM transmitter?
The best station for your FM transmitter is one whose frequency isn’t in use, at least in your present location. It can be anything between 88.1 and 107.9 FM, depending on the frequency you prefer.
