Are USB Audio Cables Different from Regular USB Cables?

There's an important distinction to make when it comes to audio-specified USB cables. Audio USB cables like Moon Audio's Silver and Black Dragon USB Cables are not meant for usual data transmission in the way that you would connect a hard drive to your computer. This is why USB audio cables will not work for high-speed/superspeed data migration or fast-charging applications. Each connector type has a specific amount of pins that the conductors are attached to. Audio cables do not need all the pins for data that usual USB cables utilize. We typically use 4-5 pins for audio transfer, which is all you need. More pins mean faster rates, more data, more conductors, and more expensive cables.

When we say that a USB cable is meant for audio transmission only, this means that the cable should only be used for connecting your source to a DAC or music streamer (just as an example). The only thing that should be transmitted through the cable is your audio data. You might ask, why would I get a cable that only does audio when I can get a stock USB cable that does everything? Answer: the same reason why audiophiles and music lovers buy a standalone DAC, or a high-end preamplifier or music streamer. The fact is that a standalone device or devices meant to do one thing, perform better than do-it-all devices. Better materials, better quality construction, and the fact that something was designed specifically for one purpose means the same thing for cables.

Audio Only Needs USB 2.0 for Data Transfer - It Will Not Benefit From Newer USB Technology

USB Audio will not benefit from the technological advancements and speeds of USB 3.0 and up. A typcial or standard 24-bit/192 kHz high-resolution stereo audio file only takes about 20mbps of USB bandwidth. USB 2.0 transfer speeds max out at 480 mbps. There is simply no need for any high data transfer size/speed for high-resolution audio for the near future.

What is OTG?

There are two different configurations offered on this webpage. Normal USB signal transfer as well as OTG (on-The-Go) USB signal transfer. What is OTG? There are two different configurations offered on this webpage. Normal USB signal transfer as well as OTG (on-The-Go) USB signal transfer. What is OTG? USB OTG is a specification that allows USB devices, such as tablets or smartphones, to act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mice or keyboards, or an external Dac to be attached to them. The USB connection is terminated slightly different than in a normal USB termination. This termination essentially tells the Android-based device to output a data stream. In the case we all care about, it is releasing digital audio so your external Digital to Analog Converter takes over control of processing the digital music on your Android based phone or tablet.

USB On-The-Go (OTG) is a standard available on many Android phones that allows portable devices to act as USB hosts. This is a great way to expand the utility of your smartphone or tablet. OTG protocol allows you to be able to connect external devices like a storage drive, camera, mouse, and keyboard to your smart device. The real benefit of this comes with transferring data. Before the OTG protocol, you would have to connect your phone to your laptop or computer, connect the external drive, flash drive, or SD card to the same computer, and initiate the data transfer through the computer. It was a tedious and time-consuming process.

With USB OTG, you can now connect the external drive directly to the smartphone or tablet, in which case the device would act as a host (like the computer in the previous example), and transfer the data directly without the use of a middleman. It's a more efficient and easier way to transfer data to your device. In order to use OTG you'll need a suitable cable or adapter from your external device to your phone or tablet. There are lots of options here, and you'll need to make sure that your devices can support OTG for this process. If you have any questions feel free to Contact Us and we'll be more than happy to help guide you through this process.

Dragon Cable USB-C Connectors

Moon Audio's USB-C cables are built specifically for digital audio transfer only. They are not designed with charging and fast speed data transfers in mind. High speed data transfer requires more conductors in a cable which would drive up the cost exponentially. That being said, while our USB cables will charge a device, they are based on USB specifications required for audio transfer only. Note that high-resolution audio data does not need any more bandwidth than what is provided by USB 2.0. This is our way of creating premium cables for incredibly low prices. For USB C charging cables we have a great affordable option HERE.

USB-C can be utlilized for both OTG and non-OTG applications as well. For example, when connecting an Apple MacBook Pro to your home DAC via USB-C, a standard USB-C to USB-B connectio is required. If you have an Android-based Samsung Galaxy phone or an Android-based digital audio player (DAP) like an Astell&Kern SP3000 to your Chord Hugo 2 DAC and Headphone Amp, then you will need a USB-C to USB micro-B OTG cable. It can be difficult to figure out, but feel free to Contact Us for help.

MFI-Certified Lightning USB Cables

Moon Audio also specializes in MFI-certified Lightning USB Cables for Apple devices like iPhone and iPad. Apple Lightning cables work in the same way as an OTG cable - they tell the Apple device to output digital audio. Note that the digital to analog converter must also be MFI-certified to accept this direct cable connection. If your DAC is not MFI-certified then a two-cable solution is required. In this case, you would need an Apple CCK adapter followed by a USB cable. The Apple CCK adapter acts as the OTG cable for this connection. For example, if you need to connect your iPad or iPhone to a Chord Mojo 2 or Chord Hugo 2 DAC and Headphone Amplifier then you would need an Apple CCK adapter plus a USB-A to USB Micro B cable. See HERE for an example of this connection kit. Also, please see our Apple-specific cables HERE.

How to connect:

Android Mobile devices to portable Dacs or Amplifiers:

  • Choose 3" right angle Micro B to right angle Micro B OTG - Perfect for use between older Astell&Kern DAPs and the Chord Mojo/Mojo 2.
  • Choose 3" right angle Micro B to right angle Mini B OTG - Perfect between an Android phone and an iQube V5 Amplifier/Dac
  • Choose 6" USB Straight Micro B to USB Straight B Micro OTG (for Android) - Perfect Between the older Astell&Kern DAP models and either Chord Hugo/Hugo 2 or Chord Mojo/Mojo 2.
  • Choose 4" right angle USB C to right angle USB B Micro OTG for newer Astell&Kern DAP models and the Chord Hugo/Hugo 2 or Chord Mojo/Mojo 2.

Quality You Can Trust

Generally, stock audio cables are manufactured with subpar materials, metals with impurities, poor geometries, and an overabundance of layers to make them look and feel like a fire hose. Inconsistency and lack of quality control in stock cables can lead to poor sound quality and a veiled sound vs. what the musician intended for you to hear and feel from the music. Dragon cables are handcrafted with the highest standards and made to order according to your specific needs. At Moon Audio, we create a Custom HiFi Audio Cable for you using the highest quality UP-OCC silver or copper conductors that can be manufactured. UP-OCC metals are void of impurities and are optimized for signal transfer and sound quality. We have one of the largest collections of audio and headphone connection options available online and we create limitless audio cable options depending on your specific gear and needs.
