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.

Like its volcanic sibling, the Tessidera embodies the marriage of artisan woodworking and acoustic innovation that defines ZMF.

 
 
 
 
 
 

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.

The ZAM lattice smooths the treble region while the SRS resonator adds weight and punch to transients, creating a cohesive midrange-to-treble presentation that rewards long listening sessions. This is not a laid-back headphone—it's a lush, engaging experience that maintains the impact and dynamics ZMF is known for, wrapped in a smoother, more refined delivery.

 

five technologies, one cohesive system

 
 

 

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.

 

 

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.
