A new chapter in planar excellence

ZMF Headphones announces the Tessidera, a new planar magnetic headphone that represents the most technologically integrated design in the company's history.

Named to complement ZMF's flagship Caldera, the Tessidera draws its identity from two sources: tessera, the interlocking mosaic tiles of classical craftsmanship, and tessitura, the musical term describing the range where an instrument resonates most naturally.

The Tessidera Sound

Where the Caldera is energetic and bombastic, the Tessidera offers a different expression of the ZMF planar vision: liquid, lush, and euphonic without ever becoming relaxed or boring. The five-technology system delivers a smooth, extended presentation with punchy excitement—a macro-dynamic headphone that trades raw energy for refined musicality.

Five Technologies, One Cohesive System

The Tessidera debuts in rich and subtly colorful Canarywood with Black Rod and Grille, brown premium mesh cloth, and introducing the ZMF Acoustic Matrix in coordinating Chocolate Brown. Choose to upgrade to a Black Mg12 Chassis with the BBB strap included; or select Black Aluminum (with the option to add-on a Black BBB, installed). 

The Tessidera represents the culmination of ZMF's acoustic research, bringing together five technologies that work not as independent features, but as an integrated system:

CAMS (Caldera Asymmetrical Magnet Structure):

The foundation of ZMF's planar technology, CAMS uses dual-sided trapezoidal N52 neodymium magnets to create even magnetic tension across the diaphragm while pushing air toward the ear with controlled diffusion.

ZAM (ZMF Acoustic Matrix)

The new lattice diffusion system that eliminates standing waves and smooths the treble region while preserving dynamics.

ADS (Atrium Damping System)

ZMF's patent-pending rear damping architecture controls pressure and airflow behind the driver, minimizing back-wave cancellation while enhancing perceived depth through strategic diffusion and driver placement.

SRS (Soundboard Resonator System)

 The new wood resonator that adds punch, controls the midrange, and brings instrumental resonance to the planar platform.

ZMF Caldera Pad System

The Caldera pads feature an inside-out fluted design that channels airflow from the driver membrane directly to the ear. Combined with semi-vented airflow and an asymmetrical angled geometry, the pad system introduces dimensionality and spatial presentation that complements the planar driver's capabilities.

Refined Driver Technology

The Tessidera features a newly developed planar driver with a 1-micron diaphragm thickness—thinner than the Caldera's 2-micron design. At 35 ohms impedance with thicker traces and ZMF's TPE construction with silver plating, the driver delivers an easier, smoother presentation that opens the Tessidera to a wider range of amplification while maintaining the technical excellence of ZMF's planar platform.

Tessidera Pads

The Tessidera ships tuned to our Stock Caldera Lambskin Top/Side Perf pads. Of everything we tested, this pairing delivered the best overall balance: fast, lively transients without sacrificing natural decay; a spacious stage with that rich, organic midrange tonality that doesn't sound like a planar at all. That said, we found some great alternatives worth exploring, which are offered as the included secondary pad options.  All descriptions may vary based on your HRTF.

Caldera Lamb TSP vs. Caldera Suede TSP

The suede surface acts as a natural acoustic absorber, gently damping upper-midrange energy and softening treble transients compared to the more reflective lambskin — you'll hear a slightly smoother, more relaxed presentation with a touch less attack which we find nice for long sessions. Suede's increased damping yields a subtly warmer, more laid-back staging character, albeit with a slightly more linear sound.


Caldera Lamb TSP vs. Caldera Thick Lamb TSP

The thicker pad increases driver-to-ear distance, which widens the perceived soundstage and shifts upper-frequency energy — you'll notice a slight boost in presence and a slightly more U shaped response that will be exciting to many, while bass weight and sub-bass extension stay very close the added air volume in the deeper chamber provides marginally longer acoustic decay and a slightly more spacious presentation.

Caldera Lamb TSP vs. Auteur Solid Suede

The thicker pad increases driver-to-ear distance, which widens the perceived soundstage and shifts upper-frequency energy — you'll notice a slight boost in presence and a slightly more U shaped response that will be exciting to many, while bass weight and sub-bass extension stay very close the added air volume in the deeper chamber provides marginally longer acoustic decay and a slightly more spacious presentation.
