Frequently Asked Questions

Q: What is a DAC USB-C headphone adapter and why do I need one?

A: A DAC (Digital-to-Analog Converter) USB-C headphone adapter converts digital audio signals from your phone or PC into high-quality analog sound for your headphones. Modern smartphones have removed the 3.5mm jack, and a high-quality DAC adapter like this one — featuring the ESS ES9318 chip — provides far superior audio quality compared to generic adapters, with support for Hi-Res audio up to 384KHz/32-bit and DSD decoding.

Q: Will this USB-C DAC adapter work with my iPhone?

A: This adapter is designed for Android devices with a USB Type-C port that supports audio output, as well as Windows 10 PCs via the included USB-A to USB-C adapter. It is not designed for use with iPhones, which use a Lightning or USB-C (MFi) connector with different audio protocols.

Q: What headphone impedance is supported by the ES9318 DAC amplifier?

A: The built-in 600Ω dynamic adaptive amplifier chip supports headphones ranging from 16Ω to 600Ω, making it compatible with a very wide range of headphones — from everyday earbuds to high-end over-ear audiophile headphones.

Q: Does this USB-C DAC adapter require any software or drivers?

A: No — this is a plug-and-play device. Simply connect it to your USB-C port (Android or Windows 10 PC) and it is immediately recognized without the need to install any drivers or software.

Q: What does DSD hard decoding (DoP mode) mean?

A: DSD (Direct Stream Digital) is a high-resolution audio format used on Super Audio CDs (SACD) and audiophile recordings. Hard decoding in DoP (DSD over PCM) mode means the ES9318 chip processes the DSD data natively, preserving maximum audio fidelity rather than converting it to PCM first. This adapter supports DSD 64, 128, and 256 formats.
