Headphone specifications can feel like a foreign language. Numbers and units that look impressive on a page but tell you almost nothing about what you will actually hear.
So here is what we chose, and more importantly, why — and what it means the moment you put them on.
The driver: 50mm
The driver is the engine of a headphone. It is the component that converts an electrical signal into sound — into air movement, into something you can hear and feel.
Most consumer headphones use drivers between 30 and 40mm. We chose 50mm.
A larger driver moves more air. More air movement means more physical presence in the sound. The bass does not just register as a frequency — you feel it. The kick drum hits. The bass guitar has weight behind it. The low end of a piano sounds like a piano, not a thin approximation of one.
This is the single biggest reason the ellipse™ sounds the way it does. It is not a subtle difference. The moment you put them on and play something with real low-end energy, you understand it immediately.
The frequency response: 12Hz – 40,000Hz
Most headphones reproduce sound between roughly 20Hz and 20,000Hz — the commonly accepted range of human hearing. The ellipse™ goes from 12Hz to 40,000Hz. That is wider on both ends.
Why does that matter if you cannot technically hear those frequencies?
Because audio does not work in isolation. The frequencies just outside the audible range affect how the ones inside it feel. Extended low-frequency response adds physical weight and warmth to the bass. Extended high-frequency response keeps the upper range open and airy rather than closed off and fatiguing.
The result is a soundstage that feels wide and three-dimensional. Like you are in the room where the recording was made — not listening to a recording of it. Vocals sit in front of you. Instruments have space around them. The whole picture is larger than you expect from a closed-back headphone.
That is not an accident. It is what we tuned for.
Closed-back design: isolation without electronics
The ellipse™ is a closed-back headphone. The earcups are sealed, which means sound from outside is blocked physically — by the design itself, not by active noise cancellation.
This is a deliberate choice.
ANC works by using microphones to detect outside noise and generating an opposing signal to cancel it out. It is clever technology, but it adds processing to the signal chain. It requires a battery. And some ANC implementations can introduce a subtle coloration in the low end — a side effect of the processing working hardest in the frequency range where music has the most energy.
Closed-back passive isolation does none of that. It just blocks outside sound through the physical seal of the earcup against your head. No processing. No battery. No interference with the signal.
For focused listening, studio work, or any situation where you want to be inside the music without distraction, this is the right approach. Simple, reliable, and always on.
Built to be replaced, not thrown away
One specification that does not appear on most spec sheets: the earcups on the ellipse™ are fully replaceable.
The velour earcups are the part of a headphone that wears out first. After years of use, the material compresses and the seal degrades. On most headphones, that is the beginning of the end — the part is glued in, the headphone goes in a drawer.
On the ellipse™, you order new earcups and swap them yourself. The cable detaches and can be replaced the same way. The aluminium and brass hardware does not wear out.
This is not a minor detail. It is the difference between a headphone that lasts two or three years and one that lasts ten or fifteen. We built the ellipse™ to be the last pair of headphones you need to buy for a long time. The repairability is part of that promise.
What all of this adds up to
The ellipse™ is not tuned to impress on a spec sheet. It is tuned to sound alive — to give you the kick drum in your chest, the vocal right in front of you, and the guitar exactly where it was placed in the mix.
Every decision — the driver size, the frequency range, the closed-back design, the replaceable parts — points in the same direction: a headphone that disappears and lets the music take over.
That is what we were after. We think we got there.
