Restraint is the loudest thing we make.
Earbuds built from recycled aluminum and recycled ABS, wrapped in full-grain leather. Built in Hong Kong.
We don't do fake-premium.
Most "premium" audio brands sell soft-touch plastic, a velvet pouch, and a film shot in slow motion. We started from a different question — what changes if the materials are actually expensive, not just lit to look that way. We partner with a recycling firm to source both the aluminum housing and the ABS structural core — nothing virgin, nothing landfill-bound. Full-grain leather, hand-wrapped. Nothing sprayed on, nothing simulated.
How ONYX came to exist.
Every earbud case on the market looked the same — plastic, disposable, and never recycled. ONYX started as a reaction to that, not a business plan.
Sketches, sourcing calls, and early drafts of what ONYX could be — recycled aluminum and recycled ABS, wrapped in full-grain leather, nothing simulated.
The first working prototype came together in Hong Kong — recycled aluminum housing, hand-wrapped leather case — now being tested and refined ahead of a wider release.
The design is locked. The final prototype brings the recycled aluminum housing, hand-wrapped full-grain leather and finished internals together for a last round of testing.
Testing wraps up and the design is signed off for manufacturing — the point where ONYX stops being a prototype and becomes a product.
