Nulaxy KM18 is the top selling FM Transmitter, though its new 2017 version KM20 is out in the market. This top hit Fm transmitter comes with a big 1.44″ screen that displays your FM frequency, Volume percentage, incoming call ID, Song Name and time while playing through TF card and USB.

A big dial for volume control with a multifunction button for the mode switch. With that you can switch to AUX, TF, and Bluetooth mode and if press long you can switch to loop, repeat or shuffle modes.

Then there are separate buttons for frequency and track control. On the right, there are AUX and TF card slots. With its flexible hose, you can control the position of the device. There is only 1 USB port to charge. No USB reading option.

It is compatible with all iPhone and Android devices. You can play music wirelessly via Bluetooth, pairing speed is fast. Also, handsfree calling is very useful with built-in mic. According to reviews, sound quality is also clear with noise cancellation technology.

Here I will prefer the Nulaxy 2017 model with more features in the same range.
