USB vs. Aux: What’s the Difference?

Which audio input is better and when should I use it?

Most phones and media players have both USB and auxiliary outputs, also known as auxiliary or headphone jacks. Both deliver music from your phone to your car or home stereo, but they work in different ways. We compared the two to help you make the best choice.

overall result

USB

  • It’s not as common or universal as auxiliary inputs.

  • Safer and more convenient driving: You can control your smartphone or tablet hands-free.

  • Not everyone will notice the difference, but the sound quality is excellent.

  • Digital to Digital: No lossy conversion of audio.

additive

  • Universal: Can be used with most smartphones, tablets, CD players, head units, portable speakers, mixers and some instruments

  • Converting audio from digital to analog can introduce noise or loss of information, but most people don’t notice the difference.

  • It tends to wear out faster than USB.

The main difference between a Universal Serial Bus (USB) connection and an auxiliary input is that USB cables carry digital information and Aux cables carry analog signals. A USB cable carries data like a computer, and an Aux cable carries audio like an amplifier or headphones.

Which cable you should use depends on your speaker system and setup. USB cables are usually more convenient and provide better sound, but they can only be used with digital systems. Aux cables are useful in situations where there is no USB or digital interface. B. Old car, record player or home cinema receiver.

In some cases, USB controls playback of the connected device. B. Car radio. Because Aux jacks only carry analog audio signals, they often do not have the same level of bidirectional capability.

Advantages and Disadvantages of Aux

Advantages

  • Universal: Can be used with most smartphones, tablets, CD players, head units, portable speakers, mixers and some instruments

disadvantage

  • It wears out faster than USB, making noise and hissing.

  • The sound quality is poor, but most people won’t notice a difference.

The great thing about Aux inputs is that they are widely used. It can be used with most smartphones, tablets, CD players, head units, portable speakers, turntables, and some musical instruments. (The biggest exception is all iPhones made after 2016.) Playback is simple and straightforward, and there are no compatibility issues that sometimes plague digital connections.

The main downside is that auxiliary cables tend to wear out faster than USB cables because of the small surface area of ​​the metal socket. Auxiliary cables also produce more audible noise due to short circuits in the current flow. Cables are often shorter, thinner and more expensive than USB. The standard isn’t as future-proof as it used to be, as Apple has announced that it will phase out the 3.5mm standard on its devices.

10 Best AUX Cables

USB Advantages and Disadvantages

Advantages

  • Great audio quality even though most people won’t notice the difference.

  • Digital to digital transformation: No information loss.

disadvantage

  • It’s not as common or universal as auxiliary inputs, especially on older devices.

When a cell phone or mobile device is connected to the head unit or other USB audio interface, the mobile device transmits unprocessed data. The head unit or speaker system uses a digital audio converter (DAC) to convert the data into an audio signal for clearer sound without loss of information. This is in contrast to Aux cables, which transmit digital audio only after it has been processed by the audio source, producing a more lost sound.

Some head units and audio interfaces directly control the smartphone via a USB connection. Also called direct control, this function is safer and more convenient while driving. The degree of integration varies from device to device.

Despite increasing usage, USB ports are not as common as Aux or headphone inputs. Aux ports are available on almost all audio playback devices except the newer iPhones. The same goes for USB.

5 Best USB-C Cables

Format and Definition: Old vs. New

USB

  • An industry standard for connecting computers to peripheral devices such as printers, audio interfaces, musical instruments, keyboards, external batteries, and hard drives.

additive

  • Any type of additional or auxiliary audio connection. Most commonly associated with the 3.5mm headphone jack.

Auxiliary input is not a specific connection type like USB. Indicates an additional or secondary connection. There are several types of auxiliary cables and connectors. The most common is the 3.5mm jack, which is the same type of tip-ring-ring-sleeve (TRS) or tip-ring-ring-sleeve (TRRS) plug used to connect headphones. (That’s why it’s called the headphone jack.)

Whenever a head unit, home theater receiver, or audio interface sees “auxiliary input”, it refers to that type of input (male to male 3.5mm TRRS cable). Home stereos usually share the same connectors and RCA, optical, 1/4-inch TS, and other connectors.

USB is an industry standard for digitally connecting computers and peripherals. Since its invention in the 1990s, USB has passed through generations and remains a wired form for connecting and controlling digital audio devices and peripherals such as storage drives, printers, keyboards, and modems.

What is a DAC?

DAC stands for Digital to Analog Converter. A DAC takes digital data and converts it into an analog signal that can drive speakers or headphones. Whenever you listen to digital audio in your car or home stereo, the DAC takes the digital information from your phone and processes it into an audio signal.

AUX input and USB are both ways to connect your phone to a stereo, but the quality may vary depending on the DAC involved. This is because the Aux connection uses the phone’s DAC. In contrast, data can be processed from a DAC in a car stereo or audio interface via a USB connection.

Overall Findings
USB

Not as common or universal as aux inputs.

Safer and more convenient for driving: Allows hands-free control of a smartphone or tablet.

Superior sound quality, though not everyone notices the difference.

Digital-to-digital: No lossy conversion of audio.

Aux

Universal: Available on most smartphones, tablets, CD players, head units, portable speakers, mixers, and some musical instruments

Converts audio from digital to analog, which may result in noise or loss of information, though most people won’t notice a difference.

Tends to wear out sooner than USB.

The main difference between a USB (Universal Serial Bus) connection and an auxiliary input is that USB cords send digital information while aux cables send analog signals. USB cords transfer data as you would to a computer, while aux cables transmit audio as you would to an amplifier or pair of headphones.

Which cord you should use depends on the speaker system and setup. USB cords are generally more convenient and deliver better sound, but are only available on digital systems. Aux cords are useful in situations where there is no USB or digital interface, like an old car, record player, or home theater receiver.

In some cases, USB controls playback from the device you’re connected to, like a car head unit. Since auxiliary jacks only transfer analog audio signals, you often don’t have the same degree of two-way functionality.

Aux Pros and Cons
Advantages

Universal: Available on most smartphones, tablets, CD players, head units, portable speakers, mixers, and some musical instruments

Disadvantages

Wears out sooner than USB, leading to noise and hiss.

Inferior sound quality, but most people won’t notice a difference.

The chief benefit of an aux input is that it’s widely used. It’s available on most smartphones, tablets, CD players, head units, portable speakers, record players, and some musical instruments. (The biggest exception being every iPhone made since 2016.) Playback is also simple and easy, with none of the compatibility problems that sometimes plague digital connections.

The main drawback is that aux cords tend to wear out faster than USB cords, due to the minimal surface area of the metal jacks. Aux cords also introduce more audible noise due to shorts in the electrical flow. The cords are often shorter, flimsier, and more expensive than USB. With Apple signaling its intent to phase out the 3.5 mm standard on its devices, the standard is not as future-proof as it once was.
