About us

Our story

Founded in 2022, LETECIEL develops headphones and other personal audio devices. The brand team is composed of senior audio and software R&D engineers, professional musicians such as violinists and pianists, and artists including painters. Devoted to technology, art and life, they channel the expertise of their respective fields into the development of every headphone. As an original brand rooted in anime culture, LETECIEL is named after its chief mascot, Hoshimi Kaku. Every headphone is crafted as one integrated piece: illustrators design its form and key visual, engineers tune the sound to match, and the theme song, character voice lines and promotional PV are produced alongside — available on QQ Music, NetEase Cloud Music and other major platforms. LETECIEL also creates IP merchandise and everyday goods — what we hope you will own is not just a pair of headphones, but a complete anime life experience.

What we stand for

✳

Design first

Every silhouette starts from the mascot's character design — illustrators draw the form and faceplate, engineers refine the fit, so a headphone becomes the piece you want to carry every day, not just a tool.

♪

Sound above all

Violinists and pianists sit in our tuning room alongside the engineers, balancing every curve of the response. We chase not a chart of impressive numbers, but a voice that feels close and an ACG track that moves you — a sound you never want to pause.

Quality you can trust

In-house production and piece-by-piece quality control. From driver matching to shell consistency, every unit is checked and re-checked before it ships — stable quality doesn't just live in development, it belongs, more than anything, to the pair in your hands: a sound you can count on from the first listen to the thousandth.
