If you’ve got an old car and have trouble getting your phone’s music to play in it, then you might want to consider some alternative hardware. While Aux connectivity is usually the first solution that comes to mind, connecting your phone with the car’s aux port seems like a cumbersome process. This is where Bluetooth Aux adapters come into the equation.

How does a Bluetooth AUX adapter work?

A Bluetooth Aux adapter establishes a wireless connection between your car and any device you choose including your smartphone, tablet, or even laptop. All you need to do is plug in this adapter into the Aux or Auxiliary port.

Almost every car in existence today comes with an AUX port out of the factory, so you shouldn’t have trouble connecting a Bluetooth Aux Adapter with your car. After this, it’s as simple as finding and pairing with the adapter using your smartphone or other devices that support Bluetooth audio streaming. If done correctly, the audio should start playing on the car’s speakers.

With this in mind, picking up a cheap Bluetooth Aux Adapter should help you enable Bluetooth connectivity in your car even if the manufacturer doesn’t support Bluetooth connectivity by default. This is also known to be one of the most cost-effective methods to enable Bluetooth audio on an unsupported car.

So let’s take a look at some of the best Bluetooth Aux Adapters out there.

Best Bluetooth Aux Adapter

1. TaoTronics Bluetooth Receiver

This manufacturer has several Bluetooth products to its name, but the one that stands out is the TaoTronics Bluetooth Adapter/Receiver. This is considered to be among the best Bluetooth adapters and with good reason. Though it has a pretty basic design, the manufacturer has ensured that it stands out from the competition. In terms of features, this device comes in a fairly small box and has a single button on the front that takes care of pausing/playing audio or even answering your phone calls.

There’s even a dedicated volume rocker on the side of this adapter, which makes sure you can control all aspects of audio without taking your eyes off the road. Keeping up with the times, this adapter comes with Bluetooth 5.0 by default and is backward compatible with older Bluetooth standards as well. The company mentions that you can pair two Bluetooth devices at a time on this Bluetooth receiver.

The best part here is that Apple users can enable one-touch Siri voice assistant to provide voice commands while driving. There’s a built-in microphone here that assists with hands-free calling at any given time. This Bluetooth receiver has a battery life of 10 hours while it can reportedly last for 200 hours on standby. There’s a micro USB charging port here, while the company offers a charging cable as well.

2. Toksel Bluetooth Adapter

This is a well designed Bluetooth Aux Adapter for your car that can save a lot of space in your dashboard. The manufacturer even offers a display on the adapter that can show the status of the audio playback as well as the battery indicator. This product can also help enable surround sound on your home stereo.

Speaking of which, this adapter runs entirely on battery power with the manufacturer claiming that it can last for up to 13 hours per charge while it can last for up to 120 hours on standby. The battery can be recharged within the car using the car charger and the supplied USB cable. As far as compatibility goes, this adapter works with practically any Bluetooth device that allows Bluetooth audio streaming via Android devices, iPhones, iPads, and more. Using this product is fairly easy, as it’s a plug and play product.

To make things even better, this car adapter comes with a couple of buttons – one that allows you to pause/play music, and another to enable hands-free connectivity while driving. There’s a power toggle on the right that lets you control the adapter’s functioning at will. There’s no microphone on this particular car adapter, which means you will have to use the mic from your phone if you’re answering calls on the go.

3. Mpow Bluetooth Adapter

This is pretty similar to the car adapter that we discussed above, but it comes with a slightly rounded design. Moreover, the buttons are combined into one which is a neat trick to save space. On the right, you will find a toggle/switch to turn the device on or off. One of the major advantages of this Mpow in-car Bluetooth adapter is that it offers a noise-canceling microphone onboard to allow crystal clear phone calls every single time.

There’s a small display on board, though it can only show some functionality related metrics and not much else. One cool feature the company has included here is the ability for the adapter to turn on automatically when you start the car. However, this will require the adapter to be charging.

This car adapter supports pairing with two Bluetooth devices at the same time with the ability to switch between them seamlessly. In addition to the large 3.5mm to 3.5mm plug, the manufacturer also offers this in a cable form if you’re looking to keep some distance between the aux slot and the adapter.

4. Tekhome Bluetooth Audio Receiver

This takes the concept of small car Bluetooth receiver to another level as it only weighs around 9.07 grams (0.01 lbs) and is smaller than your conventional key. In fact, this size is perfect for a car aux adapter given that it can basically blend in with any design. However, the size isn’t without its limitations. The manufacturer mentions that it will not work with PCs or media players, which narrows down its use to only cars.

We love the fact that it has an LED indicator, which can be very helpful during night driving. The lights are not stationary, however, as they can change depending on the battery status. Thanks to the inclusion of Bluetooth 5.0 technology, connectivity, and sound quality is far superior as compared to conventional Bluetooth adapters. This receiver can last for around 5 hours on a single charge, and can be charged using any micro USB cable.

There are conveniently placed buttons here that allow you to pause/play audio, and even skip tracks or increase the volume. This means the driver has extensive media controls even without the phone around which helps keep your eye on the road at all times and avoid distracted driving. Users can also reject or answer calls from this device, making this one of the smallest yet the best devices we’ve come across.

5. TUNAI Firefly Bluetooth Receiver

This Bluetooth receiver has a slightly unconventional design, but it’s also one that works the best in most circumstances. One of the big differences with this receiver is that it needs both a 3.5mm aux port and a full-sized USB slot to function. While this may be hard to achieve on some cars, the feature basically negates the need to charge this adapter given that it’s always powered on.

The cable between the 3.5mm and the USB plug maintains some separation which can be handy if the two slots are not positioned together on your automobile. There’s also an extender cable to help. This aspect also means that this can only be used with cars and it won’t work as intended on products like home stereo. After you’ve plugged in both ports, the job is pretty much done.

It runs on the Bluetooth 4.2 standard which means it’s compatible with practically every device out there. Perhaps the biggest downside with this product is that there are no buttons on board to control audio or answer/reject calls. However, you can enable hands-free calling if you have Google Assistant or Siri enabled on your phone.

6. SONRU Bluetooth Aux Adapter

As you can probably tell already, this Bluetooth car adapter is slightly unconventional in terms of design, but that’s not necessarily a bad thing. This product runs on Bluetooth 4.2 which basically means that it can run with practically any modern-day smartphone, tablet, or music player out there, though we would’ve much rather liked to see Bluetooth 5.0 here.

In terms of battery life, the company mentions that this car adapter can run for around 12.8 hours at a time while the standby time is rated at 250 hours. This is pretty impressive by any measure and gives it a significant advantage over rival offerings. It has a micro USB port while a cable is offered in the retail packaging as well. Moreover, the 3.5mm cable is removable on this adapter which means that you can plug in your own lengthier cable if you need more distance between the adapter and your car’s aux port.

Though it only has one button, it can let you control audio or even answer/reject phone calls. The best part here is the inclusion of a microphone, making this an excellent adapter to enable hands-free calling on your car. The manufacturer offers a 12-month warranty with this adapter.

7. ZIIDOO Bluetooth Transmitter

This is one of the few aux receivers that come with Bluetooth 5.0 on board. Though the design is not too flattering, the manufacturer has packed in some exciting features underneath. The inclusion of a dedicated button/toggle to enable transmission mode or receiver mode makes this one of the most versatile devices in this segment. This adapter also has a wide compatibility list including home stereo devices.

The battery life here is fairly decent, though certainly not comparable with the best Bluetooth adapters in the business. There’s a dedicated button on the front of this adapter that lets you pause or play music while also serving as the power on/off button. This can be somewhat confusing but not too hard to get used to.

We also like the fact that the 3.5mm cable is removable which allows you to add your own. If you’re looking for a budget-friendly Bluetooth car receiver that can also act as a transmitter, this one has to be on top of your list.

8. Comsoon Bluetooth AUX Adapter

This is a well-designed Bluetooth car adapter in line with some of the devices we’ve talked about earlier in the article. The first thing that every prospective buyer is looking at is sound quality. In this regard, this particular car Aux adapter is one of the best thanks to the inclusion of Bluetooth 5.0.

There’s a builtin microphone included here that offers crystal clear phone calls each time and also comes with noise cancellation included. Both of these features combined make for excellent hands-free calling. The company also mentions that this device comes with a CVC 8.0 Noise cancellation for high fidelity audio quality. This Bluetooth car adapter can reportedly last for up to 16 hours on a single charge. It can be juiced up using the Type C fast charging cable which is also included in the package.

9. PALOVUE Bluetooth Aux Receiver

This is very identical to a Bluetooth receiver we discussed earlier, and perhaps one of the few devices out there that needs no charging. This is primarily because it remains powered at all times via the USB port. This product is also known as a car kit which basically establishes a stable Bluetooth connection with your automobile using the 3.5mm Aux port as well as the USB port.

This offering by Palovue comes with Bluetooth 5.0 technology built-in which basically means that it can establish a stronger connection with Bluetooth devices, and there are quite a few out there right now. In addition to using your smartphone wirelessly, you can also use your iPods or tablets for Bluetooth audio streaming. A notable design attribute here is the braided cable.

Unlike other Bluetooth car adapters, this product doesn’t come with a removable 3.5mm cable which is understandable given the design. Topping off the features list is a single LED that tells you if the device is paired and working or in standby mode. This product also comes with a built-in microphone that offers support for hands-free calling with compatible Bluetooth devices.

In addition to working in your car, this can also be an excellent addition to your home media or even wired headphones to enable Bluetooth audio streaming. The manufacturer mentions that the device can work for 8 hours at a time, which is pretty decent for a Bluetooth audio receiver of this size.

In terms of audio quality, the company mentions that the adapter supports 24-bit stereo audio, making it compatible with most car Bl audio systems out there. There are a total of three multifunctional hardware buttons here with one dedicated to pause/play music or answer/reject calls. The up and down button serve as skip and previous buttons as well as a dedicated volume rocker. This is an excellent use of the limited space available on a car adapter though it can be quite for first-time users.

This car adapter comes with dual microphones that are complemented by noise reduction technology. Needless to say, hands-free calls are going to be a breeze with this particular offering. This adapter can be charged with a micro USB cable, which is a common feature among Aux Bluetooth adapters.
