Description
Key Features
What Is OTG?
OTG (On-The-Go) lets a USB-C device act as the host for a USB peripheral.
Our cable’s 5.1 kΩ pull-down resistor on the CC line signals host mode, so your phone,
tablet, or computer outputs a digital stream to your Micro-B DAC for high-fidelity playback.
Compatibility
Works with
- Android USB-C phones & tablets (OTG audio)
- Apple USB-C iPhones (15 series) & iPads
- Windows / macOS laptops with USB-C
- Portable DACs/DAPs with USB Micro-B input
Notes
- Lightning-only devices need Apple’s Lightning USB adapter.
- Some DACs require more power than a phone/tablet supplies → use a powered hub.

FAQs
Will this cable power my DAC?
Most portable DACs draw bus power. If your DAC needs more current, use a powered hub.
Does this work with Apple?
Yes — USB-C iPhones (15 series) and USB-C iPads.
The built-in 5.1 kΩ Rd puts the device into host mode.
How do I check if my device supports OTG audio?
Look for USB Audio Class (UAC1/UAC2) support, or test with a class-compliant DAC.
