Caldera Closed LTD Teak

Caldera Closed: ZMF's first fully closed planar headphone, developed from the Caldera Open model. Awarded Headfonics Best Ortho 2023, the Caldera Closed features the patented Atrium Damping System, Caldera Pad and Caldera Magnet Systems. Sonically the Closed version imparts the speed, immediacy and dynamism of the open, while adding a sub-bass boost and tastefully closer(ish) to Harman tuning with the incredible isolation of a closed back.

Aesthetically the Caldera Closed for the first time uses a geometrically "Caldera Volcano" influenced cup shape, with asymmetrical dips and dives that allow the sonic character of our driver to shine through. A unique shape that feels amazing in the hand and much lighter on the head than you could ever imagine.

In the canyons and peaks of the Caldera Closed, teak's full arc shows off. The long, even grain wraps the cup the way it runs along a hand-laid deck, with natural oil giving the surface a soft satin sheen even before it's finished. Darker mineral lines and streaks make each pair unmistakably its own. Brass rods on Amber Mg12 add a nod to marine hardware and teak's long history at sea.

ZMFnovember 1-of-1s: Individually built in a variety of configurations, with each pair distinct in grain pattern and color. You choose the set you love most.
