The purpose of a FM transmitter is to broadcast a signal from a portable device such as a smartphone to a stereo system. Most FM transmitters will feature Bluetooth that enables a wireless connection to your audio device without the needing an aux cable.
The best FM transmitter is the upgraded Nulaxy Bluetooth Transmitter, which has additional functionality such as sleep or wake mode and four different music playing modes that include Bluetooth, TF Card, AUX and USB.
Popularity of FM transmitters has seen a large increase because drivers simply want to listen to their own music as opposed to the radio. Without a Bluetooth or AUX, USB or TF card stereo, this has not been possible without the use of a transmitter.

Both the VicTsing and Nulaxy are very similar in terms of performance and features but the VicTsing is slightly cheaper. For that reason, it is the best FM transmitter for the money and will not disappoint.
IMDEN FM Transmitter For Car
For those that are looking for something stealthy and compact, the IMDEN FM transmitter is ideal and works right out of the box. It is important to keep in mind that it is primarily for Bluetooth connectivity as there is no AUX input.
Features of the IMDEM Bluetooth FM transmitter include:
- Real time car voltage meter

LDesign Wireless FM Transmitter
The LDesign FM transmitter is a completely different style to the rather large alternatives. It is also aimed at those that are on a budget and require multiple methods of listening to their music other than just Bluetooth.
Features of the LDesign FM Transmitter include:
- Available in 7 different colors
- TF, AUX, USB and Bluetooth play modes
- Frequency ranges between 87.5 and 108.0
- A2DP sound processing for improved quality
- Sleek and lightweight design

The main drawback with the design is that it has a limited display for caller information. However, if this is a key feature, you should opt for the more expensive Nulaxy or VicTsing alternatives that offer this. Overall, it offers excellent value for money and a unique design compared to other FM transmitters.
GOgroove FlexSMART X2 Bluetooth FM Transmitter
The Gogroove is a premium FM Bluetooth FM transmitter that allows for 2 devices to be connected simultaneously. As this is a more expensive device compared to the alternatives, it comes with an impressive 3 year warranty for peace of mind.

- LED display
Overall, it is a high performing car FM transmitter with usable features and an intuitive design. However, it is the most expensive device and when you compare it against the likes of the Nulaxy or VicTsing, it may not seem worth it.
However, if a long Gooseneck design is required, then this is by far the best option. Some cigarette lighter ports make it virtually impossible to use a FM transmitter but the Gooseneck makes things much more easier.
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 cost effective FM transmitter, you can switch to music streaming of your own music without any wires or complicated setup.
However, it is not just audio streaming that a FM transmitter can offer, it can also act as a Bluetooth handsfree car kit for safe and legal phone calls.
There are hundreds of different types of transmitters available and many that are cheaper than the ones recommended within this article. However, most of these cheap alternatives use older Bluetooth technology and are not viable options for handsfree calling. On top of this, they often do not offer long warranties.
The main purpose of the FM transmitter is to tune into an unused frequency on your stereo and match it to the FM on the 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.
All of our recommendations use Bluetooth for audio streaming but there are other forms of outputting the audio. Other modes include using the USB, TF and AUX input but the simplicity and compatibility with your smartphone make Bluetooth by far the best option for audio streaming.
Hot Key Buttons
The buttons on a Bluetooth FM transmitter can make a world of difference when using the device. Large hot key buttons that are easy to reach and do not require you to look down can make a huge difference. These buttons will be used for switching between songs and answering calls without touching your phone.
The majority of 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, which results in so many transmitters being returned.
If the fuse is working, check the continuity using a automotive multimeter to see if there is any current running to the cigarette lighter.
For those that are using their cigarette lighter for other devices, you could invest into cigarette lighter adapter, which gives you additional sockets.
The design of the FM transmitter varies massively too and much further than you would think. Not all cigarette lighter sockets provide adequate room for a FM transmitter to fit properly. However, with a Gooseneck design, you are able to use the gooseneck to allow the FM transmitter to have more room and be more visible.
Large displays are also very desirable because they are able to output signal strength, voltage, audio and caller ID information. Those that are smaller will simply display just the frequency.
Drawback of FM Transmitters
FM transmitters are one of the best inventions in the car audio industry but there is one main drawback. If you travel long distances, the FM station that you choose may reach another radio station that would not be present in your local area. This may interrupt with your audio streaming and become frustrating when travelling far distances as you may find yourself switching FM stations quite frequently.
If you cannot afford a new head unit with various audio inputs, then a FM transmitter is your best option. They are cost effective, easy to use and compatible with virtually all devices. When choosing a device, we highly recommend purchasing a Bluetooth FM transmitter as its the best audio playing mode compared to the AUX, USB and TF card alternatives.
