ZMF
Caldera
Introduced 2022$3,499 MSRP
The Caldera is ZMF Headphones' first ground-up proprietary planar magnetic driver design, an open-back over-ear headphone that emerged from roughly six years of R&D and represented a departure from the brand's earlier dynamic-driver and modded-driver lineup. It pairs an 80 mm planar driver using ZMF's CAMS (patent-pending) technology with a carbon-fiber baffle and a choice of natural or aged wood earcups such as American White Oak or Zebrawood.
