Best FM Transmitter That is Under $20

Today I’m going to be reviewing the Nulaxy KM24 Bluetooth FM Transmitter for your car. This is a great product to have if you have an older car with no Bluetooth or even no aux capability. I think this is the best FM Transmitter that you can buy for under $20.

You can play your music in many different ways and it is super reliable. This FM Transmitter has the Amazon’s Choice Recommendation, so you know it’s legit. If I were you and I was interested in purchasing an FM Transmitter, I’ll add this to my cart.

Unboxing Nulaxy KM24 Bluetooth Car FM Transmitter

The presentation is great for the price, but it’s nothing too special. I do like how it’s very straightforward and how protected the KM24 comes in though. Inside the box, you get a warranty card, user guide, 3.5mm to 3.5mm aux cable, and the FM Transmitter itself.

The KM24 plugs into your standard cigarette lighter socket. Towards the bottom, you have your power switch and a 5 volt-2.1 Amp USB charging port to charge your device. The power switch is to turn on and off the FM Transmitter so you don’t waste your car’s battery. Farther up, you have the flexible neck that you can use to adjust the angle of the top portion of this FM Transmitter. The flexible neck is pretty sturdy and will hold the angle you set.

All of the controls are on the head portion of the KM24. The volume knob adjusts your volume but it can also play and pause music, and answer and end calls. It’s tactile so that you can get very accurate when adjusting your volume. The CH button changes the frequency, the M button changes the mode, and you have rewind and skip buttons.

Hands-free Calling

Towards the top, you have a screen and a microphone that you can use when taking phone calls. The other person can hear me clearly when using this mic, but they can hear the car more audibly which means you can hear more background noise compared to a regular phone microphone. However, this is basically hands-free calling which means it’s safer while driving.

Play Music from A 32GB MicroSD Card

On the left side, you have a slot that you can put a Micro-SD card with songs into to play music. I believe that 32 gigabytes is the maximum storage capacity that it can read.

Play Music from A USB Drive

On the right, you have another USB port and an aux input. This USB port isn’t for charging. It has the same function as the Micro-SD card reader on the left side. You plug in a USB flash drive with songs and play music from it.

This FM Transmitter has a lot of options when it comes to where you play your music from. Using the KM24 is very simple to do. All you have to do is find a station on the radio that is not being used. Basically, if the frequency is just static, you should be able to use that particular frequency to play your music. All you have to do now is change the frequency on the FM Transmitter to the one that you found and you should be able to play your music now.

Of course, you can also play any other sort of audio that you want. The frequency range is from 87.5 to 108.0 which is a very wide range.

Play Music from your Device

My favorite way to play music is through Bluetooth. The pairing process is the standard Bluetooth pairing process, which is really quick and simple. You can pair pretty much any device that has Bluetooth capability which is nice. There are voice prompts when you turn on the FM Transmitter and when you pair your device which makes it easier to operate. The audio is very clear and I have had no connection issues when playing music through a Bluetooth connection. There’s no delay when playing music either which is great.

Display Features

The display is fairly bright and very clear. It’s a 1.44 inch display which isn’t huge, but I can read it with no problems at all. I can even see the screen in broad daylight. The information like the frequency you’re using, if you’re connected to a device, and what song is playing is right there on the screen. It even displays the phone number of the person when you’re in a call.

Appearance

The construction of the KM24 is mostly plastic, but it’s pretty solid. The flexible neck looks to be metal which is great because you’re going to be bending it a lot. With that being said, this thing is going to be staying in your car which means you won’t be moving it around a lot. I should mention that the radio that I currently have is very basic and a little broken, but this little product, for about $20, adds a lot of functionality to your car.

I personally think that it looks really cool, and it’s black which means that it can go with pretty much any car interior. There is no branding anywhere on the KM24 which makes it look really clean. It’s also portable so you can carry the KM24 in your bag and use it in, for example, your friend’s car if you’re catching a ride. It has a glossy finish to it though, so it is a fingerprint magnet, but that’s by no means a deal breaker.

Conclusion

Overall, the Nulaxy KM24 FM Transmitter is an amazing product and it’s a must-have if you like to listen to music in your car, but don’t have a modern radio with an aux port or Bluetooth connectivity. You can play music through Micro-SD, USB-A, Aux, or a Bluetooth connection, so you have a lot of options. This FM Transmitter, in particular, is very to set up and use, and the sound quality is amazing. It has definitely exceeded my expectations when I initially saw this FM Transmitter.

I think that it’s the best FM Transmitter for the price and I highly, highly recommend this one.
