The 10 Best iPhone FM Transmitters for Your Car in 2018

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.

With a sleek design that blends right into the background, Nulaxy’s Bluetooth car FM transmitter is a smart choice. Large menu buttons control the main functions of the transmitter, with seven buttons in total for channel selection, pause/play, shuffling music and making/answering calls. Incoming calls are displayed via a caller-ID-like feature on a 1.44-inch LED display. The display also shows the selected channel as well as signal strength and which device is currently connected.

The body of the transmitter can be angled up to 135 degrees in either direction for finding the best visibility while driving. Compatible with a variety of devices, the transmitter plugs into any car cigarette lighter or 12V auxiliary outlet. Once plugged in, it only takes a moment to connect it to your device via Bluetooth. Alternatively, Nulaxy provides a wired 3.5-mm cable for non-Bluetooth devices, as well as a TF card slot. Music can be installed on the TF card for offline listening, although the shuffle and repeat modes don’t work when played offline.

This car FM transmitter delivers crystal clear sound to deliver high quality audio when connected to your iPhone via Bluetooth. CVC technology delivers a duplex sound with noise cancellation technology to produce the most faithful reproduction of sound possible when accounting for radio interference.

In addition to stellar sound quality, this Bluetooth transmitter wirelessly transmits calls from mobile to the stereo system and can switch to handsfree mode from music whenever someone calls you. 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.

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.

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, newer iPhone 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.

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.

The GOgroove FlexSMART X2 has a gooseneck design that plugs directly into any DC outlet and allows you to find the ideal angle for reading the display. Once in place, the transmitter can sync up to two devices simultaneously for broadcasting music from multiple iPhones. The central knob rotates to navigate through available FM channels and switches to volume control when pressed. Placed around the knob are three buttons that work to play/pause audio, fast forward, or skip backward.

On the right-hand side of the transmitter is the monochromatic LED display that shows the currently selected FM channel and volume level, as well as a pair of buttons for answering and ending incoming phone calls. A five-volt USB port is available for charging most smartphones if the transmitter is using one of your existing car charging ports.
