Convenience: Aux Is Faster Universal And Wired

  • Ranges up to 33 feet but requires a pairing process.

  • Not as universal as Aux, but increasingly common.

It’s easy and perhaps faster to connect a phone to a speaker system with an Aux cable, but the presence of a cord limits the range between a device and its host. There’s no need to digitally set up an Aux connection. You only need a headphone jack that runs from the audio source to an Aux input on a speaker or receiver. Unlike Bluetooth audio, however, Aux connections require a physical cord, which can get lost or damaged.

Bluetooth is a wireless standard, which allows for more freedom of movement between a device and its host. Most connections are effective at distances of up to 33 feet. Some industrial use cases range up to 300 feet or more. For car audio, Bluetooth connections allow for hands-free control through virtual assistants like Siri. This also allows you to make hands-free calls, which you cannot do with an Aux connection.

Bluetooth connections can be finicky. To connect a phone or media-playing device to a speaker system, you must place the speaker on a discovery mode and use a phone to locate the speaker. This process is not always as easy as advertised. If two devices don’t pair, repeat the process until it works. Because software is always updated, old or outdated devices can be a challenge to connect. Some pairings also require a passcode to complete a connection. All this can make the process of playing audio more of a startup hassle than an Aux cord.

Parrot is a leader in Bluetooth technology. Let’s start with the basics, the Parrot Minikit Slim. This is a simple portable speakerphone kit. It is self-contained, so you can carry it just about anyplace. Now, it also accesses the phone list inside your mobile phone and it has voice recognition, which means that you can just say the name that you want to dial and it happens. The main thing to remember right now is that these are both fully integrated car kits. They have a brain that wires directly into your car stereo. The nice thing about hard-wiring is that it gives this system much more functionality than just the portable device that basically just handles calls. It also has this dual mic array with built-in noise reduction so your callers can hear you much more clearly.

Types Of Bluetooth Adapters

Before we dig any deeper, lets look at different types of Bluetooth adapters that are available. Well be looking specifically at auxiliary adapters, but its important to understand what other options you have.

Auxiliary adapters are generally your most affordable option, and theyre the easiest to use in most circumstances. You pair your phone or MP3 player with the adapter, and plug the adapter itself into a 3.5mm auxiliary port. This allows you to connect not just to a car, but also to stereo systems. That said, it does require you to have a 3.5mm aux port to plug into.

FM adapters are a good choice for older vehicles which dont have an aux port available to plug into. These tend to cost a little more than auxiliary adapters, but they work with any car or stereo that has an FM receiver built in. You pair your phone or MP3 player with this kind of adapter just as you would with an aux adapter, and then select an FM channel to transmit over. These adapters can get annoying if youre driving long distances, though, since youll constantly have to change frequencies to a channel that isnt being used locally.

Compatibility: Aux Is Ubiquitous But Only For Audio

  • Aux inputs are found on CD players, car head units, portable speakers, record players, home theater receivers, musical instruments, and smartphones and tablets.

  • Only compatible with other Bluetooth devices.

  • Not only for sound systems. Also connects keyboards, printers, headsets, drawing tablets, and hard drives.

Because Aux connections are analog, there’s a wider range of compatible sound systems. Almost every audio-playing device has a wired Aux input, including CD players, head units, portable speakers, record players, home theater receivers, some musical instruments, and most smartphones and tablets. The biggest exception is every iPhone made since 2016.

Bluetooth connections are completely wireless and work with an array of peripheral devices, not just sound systems. Bluetooth can be used to connect keyboards, printers, headsets, drawing tablets, and hard drives to a host device. However, because Bluetooth connections are wireless, Bluetooth is less compatible with old or archaic sound systems.

While self-driving cars are making some serious advancements, the one in your driveway might be a bit less cutting-edge. So your car doesn’t have built-in Bluetooth no problem. The best Bluetooth car adapters upgrade your vehicle’s wire-free capabilities for relatively cheap. At the very least, your Bluetooth adapter should be able to play music and make hands-free calls through your car’s stereo system from your smartphone รข but you should also consider the means of connection and the additional features while shopping.

First, know which ports your car has. Some adapters plug into your car’s 12-volt auxiliary power outlet . Others use the auxiliary input that looks like a headphone jack, and some might even work through a car’s cassette player.

Even if your car has a few of these ports to choose from, each type of adapter has its pros and cons. For example, an adapter that plugs into the 12-volt outlet won’t need a power source, but it’ll probably require that you tune your Bluetooth to a specific radio station. Aux adapters, on the other hand, play straight through your car , but they often need regular recharging.

These five Bluetooth adapters come in a wide range of types to suit most cars, and they have some pretty cool additional features, too.

What To Look For

Car compatibility: The most important thing is that you need to make sure the Bluetooth receiver will work with your car. Most cars will have a 3.5mm AUX input. If your car doesnt have a USB port, some Bluetooth receivers will require you to purchase an inexpensive USB charger that plugs into the cars 12-volt DC outlet .

Charging ports: Many of today’s Bluetooth receivers come equipped with one or more extra USB ports. This is ideal for people who want to stream music and charge their smartphone while they drive. These extra ports typically increase the cost of the receiver, however.

Size and extra features: Finally, you want to make sure the Bluetooth receiver works best for you. They come in all different shapes and sizes and you might not want a bulky Bluetooth receiver to take up vital dashboard space. Also, some options come with various features, like a built-in radio transmitter or a built-in voice assistant , that you may or may not want.

Bluetooth Car Kit Prices

  • In the $20 to $35 range, expect to see a mix of high-end, hands-free kits and models with buttons optimized for phone calls. If you take a lot of calls in the car, or if you want a basic unit that has a few extra features , look at kits at the top end of the price range.

What To Do If You Have A Whiny Audio Cable

If youre hearing a whine with the audio cable plugged into your cars aux-in jack, as we have with some units, this is likely due to radio-frequency interference from your car, or even your USB charger. A ground-loop noise isolator should help eliminate the buzzing. But be aware that there can be trade-offs. When we tried one with our previous top pick, the discontinued iClever Himbox HB01, it actually decreased the overall volume and bass response, and left a slight distortion buzzing over the audio we found some Amazon reviewers whod had a similar experience. This might not be the case with every isolator cable on the market, but given the chance of a loss of audio quality, a high-pitched background whine could be a fair trade-off.

Who This Is For

If youre driving an older car without built-in Bluetooth and you want to be able to jam out to your tunes and make calls over your cars speakers without having to install a new car stereo, you have a few options. The three most common ways to accomplish this are with a Bluetooth receiver that plugs into a cars auxiliary-audio port with an FM transmitter that takes your phones Bluetooth-audio output and broadcasts it over FM radio waves that your car stereo can pick up or with a dedicated Bluetooth speakerphone. The first two options let you listen to music or phone calls over your cars speakers the third option, a Bluetooth speakerphone, has its own built-in speakers and is designed with better call quality in mind.

Guide : Digital Era Radio/cassettes And Cd Players

In the digital era, things get a touch more complicated. This refers to head units that use digital displays and push button controls, with a microcontroller running the whole show. Interestingly, many 1980s and 1990s radios used simple 4-bit microcontrollers, which had just enough capability to run a simple head unit while being presumably cheaper than the more usual 8-bit parts. Basically, if your 80s or 90s stereo has an LCD on it, this part of the guide may be for you.

Digitally-controlled decks typically use a chip called a mux or a multiplexer to determine which signal gets sent to the amplifier. The mux is basically a chip with many inputs and a single output. The main microcontroller in the head unit will typically control the mux chip, either by toggling a few GPIO pins or using a serial, SPI, I2C, or other interface. When a user presses the button for the FM radio, for example, the microcontroller will send a signal to tell the mux to route the FM radio input to the output to the amplifier. If they hit the button for tape, the microcontroller will instruct the mux to route out the tape audio instead.

Thus, by controlling the mux, you can control the audio that gets to the amplifier and thus the speakers. Depending on the mux chip used, and how integrated it is with the rest of the hardware in the stereo, this can be easy or rather difficult.
