This Caldera Closed LTD features one of the most storied and striking woods ever to grace a ZMF headphone: Cocobolo.
Black Chassis
Aged Copper Rods
Espresso BBB Strap
Known for its deep reddish-brown hues, dramatic grain contrast, and natural luster, Cocobolo is as bold in sound as it is in appearance. We've used Cocobolo sparingly over the years due to its density, rarity, and the sheer challenge it presents during crafting—but when we do, it's always for something special. This limited run showcases hand-selected, highly figured Cocobolo, sourced from sustainably harvested Central American stock and seasoned in our private wood reserve.
At ZMF, our use of Cocobolo is rooted in reverence—for both its acoustic properties and its visual allure. Cocobolo isn’t just a wood; it’s an experience. It brings a unique sonic weight and clarity, pairing beautifully with the Caldera Closed's planar driver to provide rich mids, articulate treble, and that unmistakable sub-bass slam.
And for those of you with a sharp eye for prestige, yes—this is the same wood that Jimmy McGill (aka Saul Goodman) famously demanded for his over-the-top office desk. Let’s just say, if you know, you know. In the (hypothetical) words of Jimmy himself:
"Now listen here, buddy. You’re not just buying a headphone, you’re investing in your future credibility. You see this wood? This ain’t some flat-packed, hex-keyed bargain bin special. This is Cocobolo. You put these on your ears and suddenly, you're not just hearing music—you’re hearing destiny. You feel me? Slip these on, and you’re one step away from world domination—or at least, looking real good trying."
Caldera Closed
ZMF's first fully closed planar headphone, built from the Caldera Open platform and winner of Headfonics Best Ortho 2023. Featuring our patented Atrium Damping System, Caldera Pad, and CAMS (Caldera Asymmetrical Magnet Structure) driver tech, the Caldera Closed offers a refined, immersive sound in a fully isolated form.
Sonically, the Closed version retains the speed, immediacy, and lushness of the Open, but brings in tighter sub-bass, more intimate vocals, and a slightly closer-to-Harman tuning—all while offering the isolation you’d expect from a true closed-back.
Headphones may vary from sample photos due to natural wood variance.
