You can save these individual sound settings and easily share them via the cloud.

Three integrated technologies in an exceptionally small package
The JIEZI combines a powerful USB chip, a high-sampling-rate DAC and ADC, and a high-precision DSP. It supports PCM 32-bit/384 kHz and DSD256 decoding, offering impressive performance at an affordable price.

Asymmetrical 3.5 mm interface, common-mode drive design
The JIEZI A, with its 3.5mm jack, is a portable dongle-format DAC/amplifier for users with 3.5mm headphones. It drives headphones with the same single-ended common-mode architecture, but its output power is comparable to that of similar devices with balanced outputs.

Lightweight and seamless design, constructed from aluminum-magnesium alloy
The integrated cable and housing design enable a truly seamless connection in an overall lightweight and compact design. The aluminum-magnesium alloy construction ensures a premium feel and long-lasting durability.

Golden ring, symbol of art and tradition
The outer casing resembles a golden hoop, adorned with auspicious clouds and geometric patterns. Though as small as a mustard seed and fitting in the palm of your hand, it offers boundless listening pleasure, as far as Mount Sumeru. The laser-engraved patterns create a multi-layered 3D contrast effect that brings the design concept to life while providing a crisp yet durable texture.

Complete compatibility, without any worries
Enjoy comprehensive plug-and-play compatibility with Android, iOS, HarmonyOS, Windows, macOS, and Linux devices. Thanks to support for UAC 2.0 and UAC 1.0, it works seamlessly with game consoles like the Switch and PS5, making it extremely versatile.

Supports app and web control for even more features
It supports connection via the FIIO Control App on Android smartphones and a web interface on computers, thus enabling access to even more user-friendly functions. These include switching between customizable PEQ presets, switching the UAC version, fine-tuned volume control, and much more.
*Due to system limitations, iOS devices cannot connect to or control the JIEZI via the FIIO Control App.

Hi-Res Audio certified, designed for great sound
This product comes from the experienced audio manufacturer FIIO, which continues its HiFi tradition with a meticulous, professional standard for every audio detail, thus guaranteeing exceptional sound.

High-quality cabling, both indoors and outdoors
The JIEZI uses high-purity, palladium-plated, oxygen-free copper, resulting in low impedance, minimal signal loss, excellent interference immunity, and stable transmission. The flexible silicone and braided double outer jacket make the cable flexible yet robust.
