Meet our detailed and comprehensive review on how to choose the best FM transmitter for iPhone!

A small gadget called the best iPhone FM transmitter is needed to connect a regular flash card with a USB connector and FM radio. Usually, the device is used in cars that are older than 10-15 years, which are equipped with primitive type tape recorders. With the connection of the device, it becomes possible to play music tracks recorded on a USB flash drive and other digital media using a radio cassette recorder.

It is possible to interact with a phone or a laptop to play audio files from them without transferring these files to a flash card. As such it greatly facilitates the life of the old car owners and allows you to do it without replacing the car stereo with a new digital audio device.

A typical device is equipped with a connector for a car cigarette lighter, from which it receives power. Virtually all models are equipped with a small display, which reflects the operating frequency and other parameters. A set of models includes a remote control that allows controlling from the rear seat.

Modern device for iPhone has a USB-connector for connecting a flash drive, and a slot for a micro-SD card. Transmitters, capable of switching to a phone or laptop, do this via a standard cord with an audio connector or via Bluetooth. Another option is to connect – with the help of appropriate applications for phones, which can be downloaded from the application store.

The main node is an electronic unit that reads the information in digital format and transforms it into an analog radio signal of the selected frequency. The reading occurs directly from the connected media, or at first, the information is rewritten to the internal memory of the device, and from there it is fed to the modulation.


When choosing the best choice for your car, it is easy to get confused in a variety of models and functions, so you must first at least be a little acquainted with the capabilities of different devices. We can divide transmitters into such types:

Cheap Budget FM Transmitters

The simplest best iPhone FM transmitters provide, as a rule, only one function – the ability to play audio on car audio from a USB-drive with small memory capacity. They are equipped with a minimum of control buttons and a small black and white display. A full scan of the playlist is often impossible; playback is performed in the order of recording in the root directory. This device does not have internal memory, and the playback quality is average.

FM-Transmitters Of The Middle Price Segment

These devices have small internal memory and a color display on which photos or other graphic images can be displayed. Due to this fact, the processing speed of information is increased in comparison with the simplest models, so the function allows creating your own playlists and process files in several different formats. As a rule, such devices can switch to smartphones and other media players with their own memory, for which a cord with an audio connector is provided. In addition, the design usually accommodates a slot for micro-SD memory cards.

FM Transmitters With Bluetooth

The absence of a cord for connecting to a smartphone ensures the convenience of using the best iPhone FM transmitter. In addition to audio playback, they serve to maintain a speakerphone, allowing you to talk on the phone without interrupting traffic on the road. There are other features – video playback, control panel and so on.


Depending on how it will be used, three user modes can be distinguished:

The source of background sound – for those who do not pay too much attention to playing melodies, do not like to create playlists on their own, and for those who can limit themselves to the simplest and inexpensive tool;

Audio + Bluetooth – the optimal iPhone FM stereo transmitter for those who spend a lot of time on the road every day, often have to answer calls, need a high-quality and convenient speakerphone. If you are one of such users, choose Bluetooth FM tool;

Maximum capacity is an option for those who value high-quality sound or feel the need to play video files.

So, choose your occasion and make a choice, depending on your wishes. When choosing such a device, be sure to check with which gadgets it is compatible, the quality of the microphone and the purity of the sound.

No, iPhone does not have such a function. The maximum that you can is to download the app that will work only through the Internet. Moreover, this is not always convenient, especially if you are in a wild place where there is no internet. Therefore, it is better to buy the FM adapter for iPhone.

This is a very long procedure. Moreover, you will not be able to guarantee the quality of the device you made, and you will spend more money on spare parts for such a device. It's easier to buy an iPhone 7 FM transmitter or a simple Bluetooth car adapter and save your time and nerves.

No, you do not need worry about the safety of the battery. It will not harm it.

Initially, the iPhone 7 FM transmitter is designed for use in a car. In your best interest, do not try to remodel the Bluetooth FM equivalent. The iPhone or another device can be connected with it only in a car.
