When driving most people love to listen to music, this love is only enhanced when hearing your favorite songs. For most people it increases happiness, concentration and decreases stress. Many cars, pickups and trucks have radio systems which integrate directly with peoples phones. Unfortunately this isn’t the case for everyone. If this is the case for you, the easiest way to play music from your phone through your vehicles speakers is an Bluetooth FM transmitter.

Bluetooth FM Transmitters are the most popular option for motorists all over the world — with good reason. This petite device fits into your car cigarette socket with ease allowing you to stream music effortlessly via your car stereo. Most also allow you to charge your phone and check the battery status of your car to.

We review what products the market has to offer, helping you buy the best quality Bluetooth FM transmitters on offer. 

Buyers Guide

It’s important to compare and distinguish the key features on any Bluetooth FM transmitter before you decide on one. There are several cheap low quality products from brands that promise a lot but deliver very little. The key characteristics of a good Bluetooth FM transmitter include:

  • Bluetooth 5.0 or 4.2 with noise reduction technology for clear and flawless sound quality
  • Next, you should look for a device that can charge your devices while it simultaneously playing music.
  • Lastly, it’s great if you can easily receive incoming calls with Hands-free technology. This should be a feature of any reputable Bluetooth FM transmitter.

Below we discuss a few features in-depth so you can use the information to make informed decisions when shopping for yours. 

Bluetooth Enabled

The most important features to look for is the device must be able to connect via Bluetooth.

Depending on the version of Bluetooth fitted in the transmitter, you often have the added advantage of higher quality audio, and a more stable connection to transmit music via FM channels. It is important to look for a FM transmitter with a minimum of Bluetooth 4.2 but preferably 5.0.

Connecting via Bluetooth is quick and simple. Once you’ve paired with the FM transmitter for the first time it will automatically connect in the future. Most people want to play audio via a phone, using Bluetooth instead of aux as it’s cleaner and cable free.

Different Inputs

It’s common and even expected that any Bluetooth FM transmitter must be able to give you different modes to access your music. Most are usually fitted with a USB port (flash drive) where you simply slip in your USB to access music. Many also provide an input for a Micro SD card to access your audio files saved on there.

Another input some FM transmitters have is an auxiliary cord which plugs into your phone’s headphone port, this feature is very useful but has become less common.

Some Bluetooth FM transmitters come with dual USB ports that allow you to charge two phones simultaneously. That can be very helpful as you don’t lose the valuable function of charging a mobile device simply to enjoy your music. Typically if there is two USB ports, one will be slower charging and the other much faster.

Noise Blocking

You should select a Bluetooth FM transmitter that can offer you the added advantage of a background noise-free listening experience. Most FM transmitters provides these features, often at a very reasonable price, don’t settle for anything less when selecting your next Bluetooth FM transmitter. Exceptional sound has become a given when buying from trustworthy brands, so using outdated technology isn’t necessary anymore, and it’s a waste of money.

Budget

Another important feature to be aware of is the price of a Bluetooth FM transmitter. Even though they’re usually not priced too high, there are some risk factors when it appears to be priced too cheap. Many poor quality products promise impressive features while not delivering.

Also, be wary of devices that are priced much more expensive than the norm. It doesn’t mean if something is expensive, it’s automatically the best buy for you. What’s more important is that it fits your budget and offers all the features that will make life more convenient.

FM Transmission 

The core function of a Bluetooth FM transmitter is the ability to effortlessly connect your music / audio to a clear radio frequency. There are many unused frequencies you can tap into with a Bluetooth FM transmitter for optimal performance.

Usually, FM transmitters are able to broadcast to frequencies between 87.5 – 108 MHz. This is the industry norm and nearly all products offer this.

Your listening experience should always be enjoyable after investing in a Bluetooth FM transmitter. If not, contact the brand for assistance or replacements.

Car Battery Status

An added feature to various Bluetooth FM transmitters is battery charge status when starting your car, pickup or truck. Most transmitters reads this information in the first three seconds when connecting to your car.

It’s a nice feature because the regular status updates when using your Bluetooth FM transmitter allows you to gauge the health of your battery. It will also alert you to whether something may be wrong with your transmitter — if it quickly depletes the battery power it may be faulty.

The sound quality is quite high making for good listening. Additionally, when you open the box it comes with a 600mm aux cable which is a nice added extra.

What I Don’t Like

It, unfortunately, doesn’t have the same capacity as its competitors that offer improved stable connections via Bluetooth. It also has limited noise reduction technology built-in. The build quality seems cheap.

Personally I’d avoid this transmitter as it doesn’t meet the standards of its competitors. If you don’t have Bluetooth on the device you want to play audio from it would be advisable to purchase the Nulaxy KM19 or the Sumind, both have Aux inputs which work well and produce good sound and have better build quality than JETech.

Pros

  • Very affordable
  • Connects easily to your device

Cons

  • No Bluetooth connectivity options
  • Poor build quality
  • Flimsy material used for adapter
