USB-C HiFi DAC Adaptor

The LORDWORLD HC1 is a compact USB Type-C digital audio adaptor that embeds HiBy's low-power HD DAC for hard-decoding PCM up to 384kHz/32bit. It targets listeners who want portable high-resolution playback from phones, tablets or computers without relying on built-in headphone sockets. The unit supports earphones ranging from 8 to 100 impedance and delivers a dynamic range of 120dB for detailed sound.

Signal purity and power efficiency

At a 32 ohm load the device achieves a distortion figure of 0.0018%, keeping artefacts well below audible thresholds during normal music and video playback. Its low-power decoder architecture draws minimal current from the host device, so battery drain stays negligible even during extended listening sessions. No active cooling is required and the adaptor remains silent in operation.

4Pin-lock Cu4 cable system

The HC1 uses a screw-cap 4Pin-lock connector that mates with the optional Cu4 cable to form a complete HiFi-grade headphone lead with integrated decoding. This locking mechanism prevents accidental disconnection when the adaptor is used on the move. The bundle replaces a traditional 3.5mm jack, letting legacy wired earphones connect directly to modern USB-C only devices.

Questions about this item

How do I install the HC1 plug with a Cu4 cable and what step is often missed?

Insert the USB-C plug into the device then screw the 4Pin-lock collar onto the Cu4 cable until it seats firmly; the step often missed is fully tightening the screwcap so the lock engages.

What maintenance or replacement will the HC1 plug and Cu4 cable need over time?

The USB-C connector and 4Pin-lock threads should be kept clean; if the screwcap threads wear or the cable jacket frays, replace the Cu4 cable while the HC1 plug itself has no user-serviceable parts.

What limit appears first during sustained high-resolution playback with the HC1 plug?

The USB-C port on the host device limits sustained current, so extended 384kHz/32bit sessions may trigger thermal throttling on the phone or tablet before the HC1 plug reaches its 120dB dynamic range ceiling.
