Expanse Open-Back, Over-Ear Planar Magnetic Headphones, by Dan Clark Audio.

Introducing Expanse, the new flagship open-back headphone from Dan Clark Audio. Expanse sets a new standard in open-back headphone musicality, soundstage, detail retrieval, and comfort. Featuring the all-new 4th generation planar magnetic driver and breakthrough Acoustic Metamaterial Tuning System (AMTS), Expanse delivers a stunningly smooth presentation to bring new depth and breadth to all your favourite music.

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.

The 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, The AMTS used by Expanse delivers industry-leading resolution without fatiguing highs users may be used to.

Together, the 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 favourite recordings.

Expanse design takes its cues from the DCA 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 colour to the otherwise all-black aesthetic.

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 418 g Expanse are also one of the lightest super-premium headphones on the market - and for portability or storage DCA have incorporated AEON 2’s elegant folding gimbal structure, allowing it to conveniently pack into a compact custom case that’s small and easy to stow.
