  • ZMF's first planar magnetic and new flagship headphone!
  • Same wonderful ZMF house sound but with more speed, clarity and bass weight.



Caldera - ZMF's first proprietary planar magnetic headphone.
In 2011, I modded a t50rp as a gift for my brother. I never would have guessed that twelve years later I'd design my own planar magnetic headphone. I knew I loved the punchy, ethereal and nuanced sound of planars. Through modding a couple thousand t50rp's into different models and tunings for enthusiasts, my "schooling" had begun, and now years later - I'm proud to present the Caldera.

Note that aged copper is a $200 premium.
