USB-C Digital Audio OTG
A Shorter, Cleaner Link Between Your Phone and DAC
Connect a compatible USB-C smartphone, tablet or computer to an external USB-C DAC, headphone amplifier, microphone or digital accessory without carrying a long loose cable.
USB-C Host to USB-C Audio Device
Purpose-Built Digital Connection
Let the External DAC Handle the Audio
The USB-C host sends digital audio through the cable while the connected DAC or amplifier performs digital-to-analog conversion and powers the headphones.
DIGITAL AUDIO
Connect an External DAC
Route digital audio from a compatible USB-C device to a supported portable DAC or headphone amplifier.
BUS POWER
Power Compatible Accessories
In OTG mode, the host device can provide limited power to a compatible DAC, with the page listing up to 5V/400mA.
USB 2.0
Data and Peripheral Use
The cable can carry USB 2.0 data for supported DACs, cameras, microphones and compatible USB-C peripherals.
Important Product Distinction
This Is a Connection Cable, Not a DAC
The cable does not contain an audio conversion chip or headphone jack. A compatible USB-C DAC, amplifier or audio interface is required.
Carries digital audio and USB data between compatible USB-C devices.
Does not provide a built-in 3.5mm headphone output.
Does not guarantee compatibility with every USB-C DAC or Android device.
Compact Mobile Audio Setup
15cm Keeps the DAC Close to the Phone
The short cable reduces excess slack when a portable DAC is carried beside a phone, clipped to a bag or placed on the same desk.
Suitable for portable stacks where a long cable would create loops or snag inside a bag.
Layered Signal Construction
Copper Conductors with Internal Shielding
The braided cable combines oxygen-free copper conductors, separate power and signal wiring, insulation and aluminum foil shielding.
Oxygen-Free Copper
Conductors designed for power and digital signal transmission.
Aluminum Foil Shield
Designed to help reduce external electrical interference.
Power and Signal Wiring
Page imagery identifies 24-AWG power and 28-AWG signal conductors.
Nylon Braided Jacket
Flexible exterior intended for portable handling and storage.

Product Details
Specifications
USB-C Only
Both physical connectors are USB-C. The original reference to a Lightning connector is inaccurate and should not appear in the product description.
OTG Support Required
The host device must support the required USB OTG or USB Audio mode. Some phones may also require a software setting or compatible application.
Peripheral Power Limit
DACs and USB accessories that require more bus power than the host can provide may fail to start or disconnect during use.
Highlights explained
Connector layout
USB-C → USB-C
This product uses USB-C → USB-C connections. Match the plug, socket and required function to your equipment; connector shape alone does not establish charging, data, audio or video support.
Cable length
15cm / 0.5ft
The listed 15cm / 0.5ft length helps you position the connected devices without relying on an unsuitable extension. Choose a length that suits the distance between the source and accessory.
Purpose-built OTG
Digital audio
Use this Digital audio connection with compatible host devices and supported peripherals. Check direction, accessory power and operating-system support. An OTG cable is not automatically an ordinary phone-charging cable.
Conductor design
Oxygen-free copper
The description specifies Oxygen-free copper conductors for the cable connection. Use the correct host and compatible accessory; conductor material does not guarantee compatibility with every device.
Practical use
Keeping a portable DAC beside a phone
Use the product for Keeping a portable DAC beside a phone, with compatible equipment and the specified connection. Plan the space, power source and accessories needed for that task before ordering.
Before ordering
External DAC required
This is a connection cable without a built-in audio conversion chip or headphone jack. A compatible DAC or audio interface is required.
