Tiny yet Powerful, JadeAudio Mini DAC and Headphone Amplifier JIEZI (芥子) Is Officially Released!
This compact headphone amplifier is named “JIEZI (芥子)”, drawing from the Buddhist parable “Though small as a mustard seed, it contains Mount Sumeru”. Just as a tiny seed can hold a towering mountain, the “JIEZI (芥子)” portable DAC/Amp, despite its small size, condenses rich acoustic technology, allowing users to fully enjoy a vast musical world.
The JIEZI (芥子) adopts an integrated cable-body design that eliminates complicated wiring. It supports 10-band PEQ tuning and curve saving/sharing, bringing high-precision PEQ tuning technology to entry-level products. Its compact body integrates multiple chips, supporting PCM 32bit/384kHz and DSD256 decoding. Users can choose between inline call control and unbalanced single-ended common-mode architecture, with distinct characteristics between A/B versions. Its golden hoop staff-like appearance and patterns showcase Chinese aesthetic style. At just an entry-level price, JIEZI (芥子) delivers professional and rich audio experiences for audiophiles.

Dual version with differentiated configurations, choose whichever you like
The JIEZI A, with its 3.5mm jack that supports in-line controls, especially for Huawei phones, can do calls, karaoke, recording, and in-game voice chat— making it a popular and versatile all-in-one solution. The JIEZI B, with its 4.4mm jack, uses the same single-ended common-mode architecture, whose power output rivals that of comparable balanced-drive devices.
Golden hoop cable design, high-quality cable material
The laser-engraved patterns create a layered 3D contrasting effect, bringing such a design concept to life while ensuring the texture is clear yet durable.
