Macro detail of the Open One earbud: a lime woven grille inside a machined aluminium ring, resting on a cobalt orchid petal.

The shell

Nothing between
you and the music.

The housing is one billet of 6061-T6, anodised black and bead-blasted until it stops catching light. No seams for wax, no logo on the outside, no chrome to polish. The lime isn’t paint — it’s the acoustic felt behind the grille.

The sound

Tuned in a room,
not a lab.

Most buds are voiced against a dummy head in silence. We voiced ours in a bad room — hard walls, a fridge two doors down, someone on a call in the hall — and kept going until the music won. The curve leans warm on purpose.

01

Dual drivers

An 11 mm dynamic for weight, a balanced armature for air. Crossed at 2.4 kHz, not fought over.

02

Quiet that adapts

−42 dB across six microphones. Transparency mode sounds like a window opening, not a microphone.

03

Spatial, tracked

Head tracking at 240 Hz. Turn your head and the band stays where you left it in the room.

Open One — response 20 Hz — 20 kHz
Open One — room curve Flat reference
A / B — same loop, two tunings
Paused

Synthesised in your browser — no audio file. Headphones recommended.

The detail

Everything,
counted.

No asterisks, no “up to”. These are the numbers we test to, at 50% volume, with noise cancelling on.
