The Best Bluetooth Adapters for Your Car

Not everyone can afford a car with all the latest technology, and that’s okay! If you are tired of dealing with aux cables and want hands-free calling and crystal clear music streaming, a great Bluetooth adapter is all you need.

Although Bluetooth technology has been around for over 20 years, many people have yet to experience the simplicity and functionality that makes this technology so wonderful. Thankfully, the latest Bluetooth 5.0 car adapters are so inexpensive and easy to use that there’s often no reason not to upgrade. We made this guide to showcase the best Bluetooth adapters on the market so that you can find the perfect one for your vehicle.

Shopping for a Bluetooth Car Adapter

While searching for your ideal Bluetooth device, consider these key factors:

  • Compatibility: There are two main types of car Bluetooth adapters; devices that plug directly into your car’s aux jack and ones that power up via a 12V socket and play music using the FM radio. Many prefer the aux jack approach since this usually leads to clearer sound with less radio distortion. It also allows you to drive long distances without having to set the device to a new radio station. Some Bluetooth adapters offer both functions, giving you even more options for using your new device.
  • Charging Functionality: Since your new Bluetooth adapter may occupy your 12V socket most of the time, it is imperative that it still allows you to charge your devices. Look for a model that offers USB Quick Charge 3.0 technology or a USB-C port to ensure your devices can get charged as quickly as possible.
  • Bluetooth Quality: The sound quality of your calls, music, and podcasts is naturally another huge consideration. Thankfully, adapters utilizing Bluetooth 5.0 technology will benefit from the best performance Bluetooth has to offer in terms of sound and connection quality. However, be wary of older devices using antiquated Bluetooth standards as this can lead to sub-par audio and occasional loss of your Bluetooth connection.
