ellipse headphones
Perfected for music lovers.
Open sound in a closed design.
ellipse™ is a closed-back, over-ear headphone designed for focused, immersive listening.
It combines natural isolation with an open, spacious soundstage that never feels boxed-in. Bass is controlled and full, mids are clear and present, and highs remain smooth and extended — detailed without becoming sharp or tiring.
Careful acoustic design allows the driver to move naturally, creating a balanced presentation with real depth and space. The result is a sound that invites long listening sessions and often makes you rediscover albums you thought you knew.
Built from durable materials with replaceable pads and cables, ellipse™ is made for years of ownership. A unique link function allows two headphones to connect directly — making shared listening simple and immediate.
Winner of three international design awards, ellipse™ reflects Baum’s philosophy: creating products that inspire people to create and share music.
Big 50mm drivers give you a wide, open sound — the bass, the space, the nuance. Music the way it was meant to be heard.
Closed-back design blocks out the world around you. No distractions — just your music, exactly as it should sound.
Soft velour ear cushions and a balanced weight mean you forget you have them on. From the first track to the last.
Plug a second pair of ellipse directly into the first. Share a song, an album, a moment — wherever you are.
Premium materials, replaceable ear pads, and a design that ages well. ellipse is made to stay with you — not to be replaced in two years.
We've spent 10+ years in studios with musicians — hearing how records are made before they reach you. ellipse is how we bring that experience home.
Try At Home — 30 days. Test ellipse in your own space with your own music. Not the right fit? Return within 30 days — easy and no questions asked.
This is what 10 years in the studio sounds like. ellipse is built on a decade of working with musicians — learning how music is made, how it should feel, and what it takes to get it right. The result is a headphone that doesn't colour your music. It reveals it. Premium sound. Danish design. Built to last.
We know how music should sound.
For over 10 years, Baum has worked side by side with musicians — in studios, on stages, and in the spaces in between. We've heard how music sounds before it reaches you. We know what the artist intended.
ellipse is built on that knowledge. Every frequency response was shaped in a real recording studio — not a lab. The result is a sound that's honest, full, and alive.
Testimonials
Marc B.
Every pair of closed-back headphones I’ve tried before has sounded either unnatural, pushing the music right into your ears, or somewhat harsh.. But not the Baum Guitars Ellipse. These are different. They just sound right.
Bob R.
A new benchmark at $499, the best bass I've ever heard from any headphone. Tight, deep, no boom. And the isolation was astonishing, I was listening in bed with my wife right next to me reading, she could not hear it at all and I was playing them loud. That's a cool feature.
Ferencz S.

Nothing irrelevant.
