Portable DAC for headphone listeners

The LORDWORLD Octave is a USB-C dongle built around a single ES9039Q2M decoding chip. It targets listeners who want higher fidelity than a phone or laptop jack provides without carrying a separate amplifier. The CNC titanium shell weighs 25g and includes a silver-plated USB-C cable plus a USB-A adapter.

PCM 768kHz 32bit and DSD256 native decode

The chip delivers 130dB dynamic range and 0.0001% distortion through multiple low-noise power stages. Dual SGM8262 op-amps provide 150mW at 32 ohms from the 3.5mm single-ended jack and 550mW at 32 ohms from the 4.4mm balanced output. A high/low gain switch matches sensitive IEMs or high-impedance headphones, while 100-step hardware volume resets to mid-level on reconnect.

Broad OS support with one Android exception

The dongle works with Android, HarmonyOS, Windows 10, Windows 11, macOS and iOS over USB-C. An official NICEHCK app adds an 8-band parametric EQ for Android users only. The 3.5mm port supports inline microphone, call recording and playback control where the host system allows. Xiaomi 14 Ultra is explicitly not supported.

Questions about this item

Will the 4.4 mm balanced output drive my existing 32-ohm headphones cleanly?

The 4.4 mm balanced jack delivers 550mW into 32 ohms via dual SGM8262 op-amps, and the high-gain setting is intended for higher-impedance loads.

How can I verify the ES9039Q2M DAC is decoding PCM 768kHz/32-bit and DSD256 correctly after setup?

Play a 768kHz PCM or DSD256 test file; the Android NICEHCK app shows the active sample rate, and the 130dB dynamic range with 0.0001% distortion means you should hear a noise-free background.

What cables and adapters are included, and what must I buy separately for a USB-A laptop?

The box contains a silver-plated USB-C to USB-C braided cable and a USB-C to USB-A adapter, so no extra purchase is needed for USB-A hosts.
