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!














ellipse™ is a closed-back, over-ear headphone created by musicians for people who love listening to music.
Drawing on more than a decade of building instruments, ellipse™ is tuned to bring you closer to the sound the artist and producer intended. Its 50 mm neodymium drivers deliver a spacious and balanced listening experience, with controlled bass, clear vocals and the detail that gives each recording its character.
With an impedance of 32 Ω, ellipse™ is easy to enjoy at home, at work or on the move. Connect it to your hi-fi system, laptop, audio interface or portable device and hear your music with the same clarity and balance.
Durable materials, lasting comfort and replaceable parts make ellipse™ a headphone designed for years of listening. The unique link function also allows a second pair of headphones to connect directly, so you can share the same music without a separate splitter.
Winner of three international design awards, ellipse™ brings together considered Danish design, long-term craftsmanship and a sound defined by musicians and made for music lovers.

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.
