USB-C DAC Adapter for Hi-Res Audio

The Fervit KT02H20 adapter converts a USB-C port into dual 3.5 mm sockets for headphones and a microphone. It targets laptop, tablet and phone users who want high-resolution playback up to 32-bit 384 kHz PCM without installing drivers. The dongle draws power from the host and works with Windows, macOS and Android devices.

32-bit 384 kHz PCM Support

The built-in KT02H20 chip decodes PCM streams at 32-bit depth and 384 kHz sample rate, which is the single figure that determines whether the adapter meets a listener's hi-res requirements. It also auto-detects CTIA and OMTP headset wiring so the microphone and remote functions work correctly. No other specification in the data defines audio fidelity.

Driver-Free Plug-and-Play Installation

Insert the USB-C plug and the adapter is recognised immediately on supported operating systems. The dual 3.5 mm jacks accept a single headset for simultaneous charging, music playback and live broadcasting. The only common issue is that devices lacking USB-C audio output or OTG support will not recognise the dongle at all.

Questions about this item

What does 384 kHz 32-bit mean when I plug this adapter into my laptop?

The KT02H20 DAC can decode PCM audio up to 384 kHz and 32-bit depth, so high-resolution files play at their native sample rate without down-sampling.

Which USB standard does the Type-C connector use and what does that limit?

The adapter draws power and audio data through the USB-C port; bandwidth is sufficient for 384 kHz 32-bit PCM stereo, so the USB link itself does not cap the advertised resolution.

What physical space do the dual 3.5 mm jacks need on my device?

Two standard 3.5 mm sockets sit side-by-side on the dongle, so you need room for both a headphone and a microphone plug next to the USB-C port.
