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.
Testimonials
Lasse Revsbech (Guitarist in BAEST & Studio Owner)
“It made me want to re-listen to all my favourite albums.”
Mary U.
These ellipse headphones deliver impressive clarity across their wide frequency range.
Jan-Matthis S.
I was very sceptical when I saw these on social media. There’s just too many bad headphones around. But then I actually listened to them and was thoroughly blown away. These sound amazing.
They’re very nuanced and have incredible sound stage. The high mids and highs were neither hyped nor phasy at all, which is what probably surprised me most. Vocals are clear as day, cymbals are detailed and crisp. The bass is very powerful and super tight - no muddiness or straining. I could have sat there for hours listening to music.
Joshua A.
What fantastic headphones! They sound wonderfully transparent and surprisingly balanced across all frequency ranges, especially in the low bass range, with a clear and nuanced sound.
Simon L.
The sound is exactly what I love and looking for. Completely clean and detailed resolution.
Christian T.
The spaciousness is astonishing for a closed-back headphone.
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 Ellipse. These are different. They just sound right.
"Ellipse feels like a sensible first headphone from a brand with real musician DNA."
"The result is a headphone that delivers an immersive and balanced listening experience while embodying the understated elegance of contemporary Danish design."

ABOUT BAUM
For over a decade, Baum has built instruments played on records, stages, and in studios worldwide. We've worked closely with those whose ideas become takes and takes become albums.
Most headphone brands have never been that close to music. We have since 2015.
THIS IS OUR STORYFROM CREATORS TO CONSUMERS
Building instruments taught us something you can't learn in a lab: how music actually sounds before it reaches you. The tone a guitarist hears in the room. The low end a producer shapes in the mix. The detail that gets lost (or revealed) by the wrong pair of headphones.
ellipse is tuned on that knowledge.
THIS IS OUR STORYFROM THE STUDIO TO YOUR EARS
ellipse carries the same obsession with sound quality and long-term craft from the moment music is created to the moment it is heard. Built for the listener who takes music seriously — and wants to hear exactly what the artist intended.
