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

Precision DSP with 10-Band PEQ

Triple-Core Integration, High-Resolution Audio

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

Golden Hoop Cable Design

Inspired by Chinese aesthetics, the gold-dome appearance and laser-engraved textures create a sophisticated, durable look.
