USB vs. Aux: What’s the Difference?

Which audio input is superior and when should it be used?

Most phones and media players have both USB and auxiliary outputs, sometimes called auxiliary jacks or headphone jacks. Both transmit music from a phone to a car or stereo, but they differ in the way they work. We’ve compared the two so you can make the best choice for you.

General findings

USB

  • Not as common or universal as auxiliary inputs.

  • Safer and More Comfortable for Driving: Allows hands-free control from a smartphone or tablet.

  • Superior sound quality, although not everyone can tell the difference.

  • Digital to Digital: No lossy audio conversion.

assistant

  • Universal: available on most smartphones, tablets, CD players, headunits, portable speakers, mixers and some musical instruments

  • It converts audio from digital to analog, which may cause noise or loss of information, but most people won’t notice any difference.

  • It tends to wear out sooner than USB.

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

Which cable to use depends on the speaker system and its configuration. USB cables are generally more convenient and sound better, but are only found in digital systems. Aux cables are useful when there is no USB or digital interface, such as an old car, turntable or home theater receiver.

In some cases, USB controls playback from the device you’re connected to, such as a car headunit. Since the auxiliary jacks only transfer analog audio signals, you usually don’t get the same degree of two-way functionality.

Useful advantages and disadvantages

Advantages

  • Universal: available on most smartphones, tablets, CD players, headunits, portable speakers, mixers and some musical instruments

Disadvantages

  • It wears out faster than USB, causing noise and hiss.

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

The main advantage of an auxiliary input is that it is widely used. It is found in most smartphones, tablets, CD players, headunits, portable speakers, turntables and some musical instruments. (The biggest exception is every iPhone made since 2016.) Playback is also simple and easy, without any of the compatibility issues that sometimes plague digital connections.

The main downside is that auxiliary cables tend to wear out faster than USB cables due to the minimal surface area of ​​the metal sockets. Auxiliary cables also make more audible noise due to short circuits in the electrical flow. The cables are generally shorter, thinner and more expensive than USB. Although Apple has signaled its intention to phase out the 3.5mm standard on its devices, the standard is no longer as scalable as it once was.

The 10 Best AUX Cables

Advantages and disadvantages of USB

Advantages

  • Superior sound quality although most people won’t notice a difference.

  • Digital-to-digital conversion: no loss of information.

Disadvantages

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

When you connect a phone or mobile device to a head unit or other USB audio interface, the mobile device transmits unprocessed data. The headunit or speaker system uses its DAC (digital audio converter) to convert the data into an audio signal, resulting in clearer sound without loss of information. This contrasts with auxiliary cables which only transmit digital audio when processed by the audio source, resulting in greater loss of audio.

Some headunits and audio interfaces take direct control of a smartphone via a USB connection. This is sometimes called direct control and is safer and more convenient when driving. The level of integration varies from unit to unit.

Despite their growing use, USB connections are not as universal as auxiliary or headphone jacks. You can use an auxiliary connection on almost any audio playback device, as well as modern iPhones. The same cannot be said for USB.

Top 5 USB-C Cables

Forms and definitions: old and new

USB

  • The industry standard for connecting computers to peripherals such as printers, audio interfaces, instruments, keyboards, power banks and hard drives.

assistant

  • Any auxiliary or secondary audio connection. It is most commonly associated with the 3.5mm headphone jack.

The auxiliary input is not a specific type of connection like USB. It means an additional or secondary link. There are a wide variety of Aux cables and connections available. The most common is the 3.5mm jack, which is the same type of ring-sleeved (TRS) or ring-sleeved (TRRS) connector used to connect headphones. (That’s why they’re sometimes called headphone jacks.)

When you see an “auxiliary input” on a headunit, home theater receiver, or audio interface, it refers to that type of input – a 3.5mm male-to-male TRRS cable. Home stereos usually have the same connection as well as RCA, optical, 1/4″ TS and other connections.

USB is an industry standard for the digital connection of computers and peripherals. Passing through several generations since its invention in the 1990s, USB remains the wired format used to connect and control digital audio devices as well as peripherals such as storage drives, printers, keyboards and modems.

What is the DAC?

DAC stands for digital to analog converter. A DAC takes digital data and then converts it into an analog signal that can drive speakers or headphones. When you listen to digital audio in a car or home stereo system, a DAC takes the digital information from your phone and converts it into an audio signal.

Aux inputs and USB are the two ways to connect a phone to a stereo, although there may be a difference in quality depending on the DACs involved. This is because an auxiliary connection uses the DAC on a phone. On the other hand, a USB connection allows the DAC of a car radio or an audio interface to process the data.
