Kendra M.
They’re an experience.
Every track I tested came through with remarkable clarity—vocals are razor-sharp, instruments are distinct, and the overall sound is powerful yet refined. These aren’t just headphones; they’re an experience
Josephine G.
The spaciousness is astonishing.
They sound wonderfully transparent and surprisingly balanced across all frequency ranges, especially in the low bass range, with a clear and nuanced sound. The spaciousness is astonishing for a closed-back headphone.
Bjørn M.
A very classy piece!
The first impression when listening shows that the entire range is reproduced with fine resolution – crisp bass, not muddy but clear – the trebles are delicate, never too intrusive. A very classy piece!










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.

We work between those who create music and those who listen to it.
Baum develops instruments and audio products in close collaboration with musicians, producers, and performers worldwide – from rehearsal rooms where ideas are formed to studios where final takes are recorded.

It makes you want to rediscover the music you already love.
“It made me want to re-listen to all my favourite albums.”

CLOSED DESIGN. OPEN SOUND.
Ellipse combines the focus of a closed-back headphone with an open, spacious, natural soundstage.
Careful control of air pressure inside the ear cup allows the driver to move naturally. This avoids the closed-in character typical of closed-back headphones and keeps the sound open and balanced.
The result is a clear, controlled presentation with fine detail without harshness or listening fatigue.
Ellipse brings the listener inside the music. Fully focus on every detail in every beat.
The result is clarity and fine detail you can live in for hours.

MUSIC MUST BE SHARED.

BUILD, COMFORT & LONGEVITY.
