FiiO JIEZI USB DAC/AMP — Type-C to 3.5mm / 4.4mm (Unbalanced) Earphone Adapter

The FiiO JIEZI (芥子) is a sleek, featherweight USB DAC/AMP that blends triple-integrated digital audio technologies with refined Eastern aesthetics. Packed inside its aluminum-magnesium body are a high-performance USB interface, a high-sampling DAC/ADC, and an audiophile-grade DSP enabling 10-band PEQ, PCM 32-bit/384 kHz and native DSD256 decoding. Available in two variants for different use cases:

  • JIEZI A — 3.5 mm jack with in-line mic/remote support for calls, karaoke, recording, and in-game voice chat.
  • JIEZI B — 4.4 mm (unbalanced, common-mode drive) jack for users with 4.4 mm plugs seeking stronger portable output.
32-bit/384 kHz PCM DSD256 Native Audiophile DSP 10-Band PEQ Type-C Plug & Play Al-Mg Alloy Lightweight & Seamless

Highlights

  • Triple Integration — High-performance USB chip + high-sampling DAC/ADC + high-precision DSP in an ultra-compact body.
  • Audiophile-Grade DSP & 10-Band PEQ — Fine-tune filter type, frequency, gain, and Q in the FiiO Control App or web interface; save and share tunings via the cloud.
  • Dual Output Options — Choose between 3.5 mm with in-line control (JIEZI A) or 4.4 mm common-mode drive (JIEZI B) that rivals many balanced dongles in drive capability.
  • Calls & Communication — JIEZI A supports in-line controls, voice calls, karaoke, recording, and gaming chat (device OS dependent; see notes).
  • Seamless, Durable Design — Integrated cable + body, lightweight aluminum-magnesium alloy construction, and elegant “golden-hoop” accent.
