to disappear.

001 — Philosophy

We designed it to vanish.

Most headphones announce themselves. Logos, ridges, status lights, plastic gloss. Aether goes the other way. Three years of obsessive iteration, removing one thing at a time, until what remained was only what the music required.

Anodised aluminium yokes, machined to a tolerance of 0.04mm. Memory-foam cushions wrapped in cellular leather that breathes. A single tactile crown for everything you'll ever need. No screens. No gimmicks. Just sound, and the room it lives in.

"We stopped asking how to make it more impressive. We started asking how to make it less. M1 is the answer."
002 — Engineered details

Five things, obsessed over.

A flagship is the sum of decisions you didn't have to make. We made these so you don't have to think about them.

Adaptive ANC

A silence that listens back.

−42DB

Eight microphones, sampled 48,000 times per second, profile the room every 8 milliseconds. The cancellation curve adapts before you notice the noise.

Battery

60HRS

Six full days. ANC engaged. 10-minute fast charge → 8 hours.

Lossless link

192KHZ

Studio-grade audio over a proprietary 5GHz channel. No compression, no drift.

Drivers

40 mm beryllium-coated, tuned in Geneva.

A sealed acoustic chamber, sub-bass to 12 Hz, ambient mode tuned with Olafur Arnalds. ±0.5dB across the audible band.

Chassis

214 g of single-billet aluminium.

Cold-forged, then bead-blasted to a low-glare matte. Memory-foam cushions in cellular leather. Replaceable. Cool to the touch at minute four.

Every measurement is a decision. These are the ones we made.

003 / 01 — Form

Three years of removing.

We started with twelve prototypes. We finished with one. Every screw, every line, every gram has a reason and a witness. What's left is what survived the question: does this make the music better?

The headband is one piece of cold-forged aluminium, machined to a tolerance of forty microns. It doesn't flex. It doesn't creak. It disappears.

003 / 02 — Sound

A driver that stops moving.

Our 40mm beryllium-coated driver weighs less than a coin and decelerates faster than physics should allow. The result is a transient response so clean that cymbals end where they're supposed to and basslines arrive without smear.

±0.5dB across the audible band. The kind of measurement you'd expect from a studio monitor that costs ten times more.

003 / 03 — Day

Sixty hours, then ten more.

Plugged in for ten minutes, you get eight hours of uninterrupted listening. Plugged in overnight, you forget the charger exists. ANC stays engaged the entire time, the cancellation curve adapting to whatever room you walk into next.

When the cushions wear, you replace them. We make this easy on purpose.

Acoustic engineering, without theatre.

Beryllium-coated 40mm drivers · sealed acoustic chamber · sub-bass extension to 12 Hz · ambient transparency mode tuned by Olafur Arnalds

Built from three things.

A flagship is the sum of the materials it refuses to substitute. We chose three. We sourced them honestly. We finished them by hand.

M / 01

Anodised Aluminium

Cold-forged, then bead-blasted to a low-glare matte finish in three earned colourways.

M / 02

Cellular Leather

Memory-foam ear cushions sleeved in micro-perforated leather. Cool to the touch. Replaceable.

M / 03

Magnetic Coupling

Ear cushions snap on, off, and onto our pebble case with the same purposeful click.

004 — In the room

A pause, filled.

The cold truth.
