Mini FM Transmitter

So you love listening to your own music, but don't have an auxiliary port or tape deck in your car? What you need is this Mini FM Transmitter from Monoprice!

This FM transmitter can transmit the selected FM frequency to your car's radio in order to play music from your smartphone or MP3 player. Simply select an open radio frequency on the FM transmitter, and tune your radio to the same frequency. Any music played through the transmitter will play through your car's sound system.

The transmitter can be tuned to any FM frequency between 88.1 ~ 107.9 MHz at 0.1 MHz intervals. It has a frequency response of 20Hz ~ 16KHz and an effective range of about 5 meters.

The FM transmitter's 3.5mm plug can be used to connect to most smartphones and MP3 players' headphone jack. It uses your car's cigarette lighter/auxiliary power socket for power, so you don't have to worry about the battery dying during your favorite song.


  • Wireless audio transmission over the entire FM frequency range
  • Works with almost any smartphone or mp3 player
  • Built-in microphone lets it function as a hands-free communications device
  • Includes car charging cable adapter with an additional USB charging port

Pros: Easy to set up!

Cons: None that I can think of!

I had a transmitter that had a lot of interference and only three stations to set my Ipod to work thru the radio stereo....this product had several options and allowed me to find a station that did not have any radio interference. Works great!

Pros: Small, simple to operate, clear signal. Does everything an FM Transmitter is supposed to do.

Cons: None

I have tried several different FM transmitters all the way back to the early iPod days. This is hands down the best one I've ever used. Small, simple and it works better than much more expensive transmitters I've used.

Pros: Clear signal and audio
Small transmitter size, good cable length
Easy to operate

Cons: Connection is a little fuzzy when using the usb charging port

An awesome FM transmitter. I really don't understand why this thing has such a low rating. It's done wonders for me. It's very easy to operate, as it only has two buttons. All you have to do is find an unused radio frequency on your car radio and set the transmitter to that frequency and boom, your music is streaming clearly to your car. The only complaint I could possibly think of is that the audio gets a little fuzzy when making use of the charging port on the transmitter, but that's nearly impossible to avoid due to the interference from electricity being diverted to the usb port rather than the transmitter. It's a problem that all transmitters that have a charging port have. All around a quality device at an unbeatable price. If you're looking for a radio transmitter for you car, your search has ended. Just buy it already
