Dan Clark Audio EXPANSE Flagship Planar Magnetic Headphone

Introducing EXPANSE, our new flagship open-back headphone. EXPANSE sets a new standard in open-back headphone musicality, soundstage, detail retrieval, and comfort. Featuring Dan Clark Audio’s all-new 4th generation planar-magnetic driver and our breakthrough Acoustic Metamaterial Tuning System, EXPANSE delivers a stunningly smooth presentation to bring new depth and breadth to all your favorite music.

And we didn’t stop at improving the sound; we also redesigned our headband to deliver a big step up in ergonomics and comfort!

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!
