A full-screen LED display quickly turns your car into something reminiscent of The Jetsons. A quartet of multi-function buttons allows for quick and easy control, and the articulating armature ensures that the Nulaxy is always within arm's reach.

LIHAN makes a no-nonsense device that gets straight to the point. The Handsfree Bluetooth Transmitter by LIHAN features a 3.1A and 1A input, offering 12v and 24v charging for both you and a passenger. Your mobile devices can charge while listening to your favorite music. Its wireless Bluetooth 4.0 connectivity also offers low power consumption with a 5 percent loss of battery to your device each hour. Like many transmitters, it includes a microphone for hands-free calling. This product has been praised for its ease of use and adaptability. More critical reviews noted that the connectivity could sometimes be an issue. Built-in Display: No | USB Ports: 2 | USB Audio Playback: MP3, WMA | Operating Voltage: 12V-24V LIHAN LHFM1039 Wireless Bluetooth FM Transmitter Review Most Adjustable Sumind BT70B Bluetooth FM Transmitter 4.2 Lifewire / Benjamin Zeman View On Amazon What we like Quick charge and standard USB-A ports Large display and buttons Clear audio What we don't like AUX input doesn't always work Difficult viewing angle for display Gooseneck cable is difficult to adjust FM transmitters have come a long way. With Bluetooth capabilities popping up on most cars, manufacturers of old-school-style FM transmitters must do a lot to differentiate. One issue is the transmitter's placement; many vehicles have the cigarette lighter buried under the console or pointed off at an angle. The Sumind Bluetooth FM Transmitter gives you the versatility to change the angle of the screen with a sturdy 270-degree gooseneck that will hold tight in the orientation you set. But that's not where the features end. There are two USB output ports for charging phones: a 2.0 smart port and a 3.0 Quick Charge port. A super-bright 1.7-inch LCD screen shows song and phone info but will also display the car battery level. There are three means of connecting audio here: your phone's Bluetooth connection, a standard aux cable, and even the capability to read a microSD card. Unlike lower-end transmitters, it supports more lossless audio than MP3, including FLAC. With support for A2DP and headset protocol, it's the perfect phone accessory for cars lacking some modern AV. Built-in Display: Yes | USB Ports: 2 | USB Audio Playback: MP3, WMA | Operating Voltage: 12V-24V Sumind BT70B Bluetooth FM Transmitter Review Best Budget JETech Wireless FM Transmitter Radio Car Kit Amazon View On Amazon What we like Sleek design Low price Simple interface What we don't like Lacks multiple USB ports No way to play audio files through USB There isn't a huge price difference between the top-of-the-line and the budget FM transmitters. 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, 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 newer iPhones that don't have headphone jacks.) The transmitter has an easy-to-read display with intuitive buttons for adjusting frequency. It also has an extra USB port to charge devices while driving. For best performance, we recommend using lower channels in the 80s and 90s. Built-in Display: No | USB Ports: 1 | USB Audio Playback: N/A | Operating Voltage: 12V-24V Best Lighting Criacr V5.0 Bluetooth FM Transmitter Amazon View On Amazon What we like Durable and compact Fast pairing Multiple charging ports What we don't like Mic isn't great Limited controls This minimalist FM transmitter from Criacr provides a quick and straightforward way to link your phone to your car's audio system. Besides allowing you to pair with various devices via Bluetooth, this transmitter also can play music from a 32GB flash drive or microSD card. The Criacr FM transmitter also features two USB charging ports to keep all your devices topped off and a trio of multi-function buttons for hands-free calling and music controls. The best feature, however, is the built-in LED lighting strip that can be set to six available colors or cycle through them to provide some necessary flair to your car. Built-in Display: No | USB Ports: 2 | USB Audio Playback: MP3, WMA | Operating Voltage: 12V-24V What to Look for in an FM Transmitter Display The most basic transmitters don’t have displays, but units with screens are easier to set up and use. Some even have caller ID or can show other important information when connected to your iPhone. Connectivity FM transmitters connect to phones using audio jacks, USB, and Bluetooth. If you have a newer iPhone that doesn’t have an audio jack, get a transmitter with a USB port or Bluetooth compatible with your phone. Hands-free calling If you go with a Bluetooth transmitter that has a hands-free mode, you’ll be able to make and receive calls without taking your hands off the wheel. Transmitters with this feature can also mute or pause your music during a call and start it again when you’re done. FAQ Does the iPhone have an FM transmitter? The iPhone does not have an FM transmitter, most phones tend not to have this feature built-in, and none of the iPhone models have ever had an FM receiver. That said, there are internet radio apps that you can use, but you won't be able to listen to actual live radio station broadcasts without using one of the transmitters on this roundup. How to connect the FM transmitter to your iPhone? An FM transmitter for the iPhone works by transmitting audio from FM frequencies to your phone. Most FM transmitters are Bluetooth-enabled. All you need to do is plug the transmitter into your car socket, pair your device, and you can start listening to the radio wherever you are. With many phones getting rid of the 3.5mm headphone jack, you're not as likely to find wired FM transmitter solutions anymore. Is there an FM transmitter app for iPhones? There are FM transmitter apps for the iPhone, like ClearFM. It lets you listen to the radio over your iPhone or iPod, giving you a list of music stations that are the clearest for your FM transmitter. You will still need an FM transmitter since the app alone won't be enough. Was this page helpful? Thanks for letting us know! Get the Latest Tech News Delivered Every Day Subscribe Tell us why!
