JIEZI (芥子): A Small Body, a Vast World of Sound

Named after the Buddhist parable “Though small as a mustard seed, it contains Mount Sumeru,” the JIEZI (芥子) portable DAC/amp offers powerful audio technology in a compact format, delivering a tremendous musical experience wherever you are.

Precision DSP with 10-Band PEQ

Equipped with a professional DSP chip, JIEZI offers precise 10-band PEQ tuning, saving curves and sharing them via the cloud through the FIIO Control app or web interface—allowing users to easily create and share their personal sound profiles.

Triple-Core Integration, High-Resolution Audio

In its small body, JIEZI combines a high-quality USB chip, advanced DAC/ADC, and DSP, supporting PCM 32bit/384kHz and DSD256 decoding—professional performance at an entry-level price.

Golden Hoop Cable Design

Inspired by Chinese aesthetics, the gold hoop appearance and laser-engraved textures create a refined, durable look. The integrated cable-body design prevents messy wiring, while premium materials—palladium-plated OFC conductors, aluminum-magnesium housing, and a double-braided cable jacket—offer both stability and flexibility.

Multi-Platform Compatibility
