Caldera – ZMF’s first proprietary planar magnetic headphone.  
In 2011 when I modded a t50rp for my brother, I never would have guessed that twelve years later I’d finish designing a “from the ground up” planar magnetic headphone.  I knew I loved the natural, punchy, ethereal and nuanced sound of planars, so off I went modding a couple thousand t50rp’s into different models and tunings for enthusiasts.  My “schooling” had begun, and now years later – I present the Caldera. For the full story, check out our YouTube Video on the Caldera.

The current stock wood for the Caldera is American White Oak.  The Oak is finished in either a natural/black cup/grille combo or a coffee gold varnish and grille color. 

Headphones may vary from sample photos due to natural wood variance.
