Most Adjustable: Sumind BT70B Bluetooth FM Transmitter

FM transmitters have come a really long way. With Bluetooth capabilities popping up on most cars, manufacturers of old-school-style FM transmitters have to do a lot to differentiate. One of the big issues is the placement of the transmitter itself; so many cars have the cigarette lighter buried under the console or point 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, including a 2.0 smart port and a 3.0 Quick Charge port. There’s a super-bright 1.7-inch LCD screen that shows song and phone info but will also display the car battery level. There are three means of connecting audio here, too: your phone’s Bluetooth connection, a standard aux cable, and even the capability to read a microSD card. Unlike some of the lower end transmitters, it supports more lossless audio than MP3 including FLAC, and with support for A2DP and headset protocol, it’s the perfect phone accessory for cars that are lacking some modern AV.

Best Budget: JETech Wireless FM Transmitter Radio Car Kit

View On Amazon

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 newer iPhones that don't have headphone jacks.)

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.
