Dan Clark Audio Expanse Open-Back Planar Magnetic Headphones

Acoustic Metamaterial Tuning System (AMTS)

Headphones are subject to standing waves in the higher frequencies, which can make instruments like strings, cymbals, even vocals sound unrealistic and fatiguing.

AMTS is Dan Clark Audio’s patent-pending inline device located between the transducer and ear. AMTS integrates waveguides, diffusion control, quarter-wave, and Helmholtz resonators into one compact structure to eliminate standing waves, dramatically improving system performance. .

Diffusion elements reduce standing wave formation while resonators act as both precision and broadband filters to smooth and shape the frequency response from the midrange through the highest frequencies.

With AMTS the upshot is high frequencies are rendered with a refreshingly smooth, accurate, and detailed delivery across all genres. OK, bad recordings are still bad, we’re not magicians!

EXPANSE Redefines “Detail”

EXPANSE’s planar driver delivers incredibly low distortion throughout the listening range with levels of detail heretofore found primarily in the top-of-the-line electrostatics. Unlike many headphones where “detail” is created through exaggerated high-frequency energy, EXPANSE’s AMTS delivers industry-leading resolution without fatiguing highs users may be used to.

Together, our 4th-generation motor and AMTS deliver a sonic performance best described as “effortless.” From a delicately plucked string to the most intense dynamics of an orchestra, or the weight and attack of a kick drum to the overtones a decay of a crash cymbal, EXPANSE delivers an amazing balance of delicacy, nuance, and punch that will have you reaching for all your favorite recordings, and maybe staying up a bit too late.

And last but not least there’s the soundstage; EXPANSE is all enveloping and can compete with any open headphone in depth, width, and imaging, with instruments occupying a correct volume in space instead of being rendered as “points”.

EXPANSE’s effortless sense of space and instrument placement allowing the headphone “disappear,” so you can simply relax into your musical experience. Let the headphones, equipment, and yes, your daily stresses melt away, leaving your music to be enjoyed the way it was meant to be heard!

EXPANSE Mechanical Design Innovations

We set out to make EXPANSE a real design statement, said Dan Clark, Founder and CEO. EXPANSE design takes its cues from our STEALTH headphone but adds an exciting and unique grill based on mathematical functions derived from the principals of generative design, for a truly unique and stylish look.

The top grade black leather headband features fine blue stitching to create a quilted head-strap that’s not only gorgeous but is also functional and comfortable. The elegant embroidered EXPANSE logo adds a dash of color to EXPANSE’s all-black aesthetic.

EXPANSE, the Ultimate in Comfort

Gone are the mechanical sliders for fit adjustment; Dan Clark Audio has designed a stable yet comfortable “self-adjusting suspension system” that seats the headphone just right, with no muss or fuss

At just 418g EXPANSE is also one of the lightest super-premium headphones on the market. Taken together, our new vegan suede and “leather” ear pads, self-adjusting suspension, and lightweight chassis make EXPANSE so comfy you can just ignore it and “vanish into your music.”

And for portability or storage we incorporated AEON 2’s elegant folding gimbal structure into EXPANSE, allowing it to conveniently pack into a compact custom case that’s small and easy to stow.
