The 8 Best iPhone FM Transmitters for Your Car

The number one best selling iPhone FM Transmitters on Amazon is chockfull of all the best qualities this line of technology has to offer. The Nuxlay KM18 offers a well-rounded price for any newcomer who wants to get the most out of an iPhone FM transmitter. It features a crystal clear blue LED display, ergonomic sound dial and buttons, as well as wireless Bluetooth connectivity.

The Nuxlay works with virtually any Bluetooth-enabled device, from your tablet to your smartphone. The device goes the extra mile with its included 5V-2.1A charging port, auxiliary port and even built-in microphone so you can take incoming calls with a breeze.

Users love the overall power and setup of the Nuxaly, with the most complaints coming from the rare occurrence of a pairing issue.

When it comes to FM transmitters, there’s not a huge price difference between the top-of-the-line and the budget. In fact, it might only come down to a few dollars. But the JETech Wireless transmitter will save you a few bucks while still getting its job done. To use it, simply connect your device via its 3.5mm headphone jack, set it to a random FM channel and tune your radio to that channel. (Remember that it won’t work with an iPhone 7, which ditches the headphone jack.)

The transmitter has an easy-to-read display with intuitive buttons for adjusting frequency. It also comes with an extra USB port, so you can charge devices while driving. For best performance, we recommend using lower channels in the 80s and 90s.

This car FM transmitter delivers crystal clear sound to deliver high quality audio when connected to your iPhone via Bluetooth.

With Bluetooth 4.2 it picks up new devices easier than ever before. It also has a sleek elegant design with blue LED lettering. Finally, you can play music from 206 stereo channels or even from a MicroSD card.

Considering most iPhone FM transmitters hover around the same price range, the main thing that differentiates them is feature controls. The Otium FM transmitter bests all others when it comes to that category. With near universal compatibility, the transmitter works with all devices that have a 3.5mm headphone jack. (Sorry, iPhone 7 owners.) It has a built-in microphone that enables hands-free calls and music streaming via Bluetooth, plus a USB port to let you charge up your other devices, even tablets. Its high-contrast 1.44-inch LED display shows information such as voltage of storage battery, song info, caller ID and more. Its controls are highly intuitive and Amazon reviewers note that it feels solidly built.

Looking for a unique style and design on par with Apple’s products? The LDesign comes in a variety of colors and is shaped like an L. It's only 4.9 x 1.5 x 3.8 inches, so it's small enough to fit in your front pocket. It comes with HI-FI stereo sound quality with echo cancellation and noise suppressing (CVC) technology. This means you can take in a call with its built in microphone and enjoy your music at a lowered volume without any overlapping sound interferences.

Besides its wireless capabilities, the device offers a TFcard and auxiliary input, so you can play music in your preferred method. It also comes with a 5V 2.5A USB port for quick charging. Buyers praise it for its design and ease of setup, while more critical reviewers state it’s prone to sound interference if your phone isn’t positioned in close proximity.

The CHGeek weighs 1.1 ounces, measures 1.3 x 1.3 x 3.4 inches and has some of the highest user ratings on Amazon to date. This is the go-to FM transmitter if you don’t want anything bulky or taking up too much room in your car.

With its Bluetooth capability, the CHGeek can connect to virtually any one of your mobile devices from your iPhone 7 to your Samsung Galaxy. Despite its small design, it’s packed with a built-in microphone that lowers your music volume when you get a call and allows for hands-free phone conversations. It also includes two dual smart USB charges, an LED voltage display and even a voice prompt that assures its connectivity.

Users on Amazon have occasionally reported some white noise static when connecting to their radios. Others praised its easy setup and Bluetooth connectivity.
