ZMF Caldera — Zebrawood (Stock Edition)
Volcanic power. Clear sound. Designed from the ground up.
The Caldera is ZMF’s first in-house planar magnetic headphone – developed after years of research for listeners who love planar technicalities but also crave natural tone, authenticity and physical presence. It blends the best of planar technology with the soul of a great dynamic design.
At the heart of the design are two exclusive ZMF innovations: CAMS (Caldera Asymmetrical Magnet Structure), a patented magnet structure that optimizes airflow and diaphragm movement, and ADS (Atrium Damping System), which controls reflections and expands spatial depth. The result is a sound that feels natural and lifelike, yet remains extremely detailed, coherent and open.
Expect deep, powerful bass, rich and harmonious mids, and clear, articulate highs without harshness. The stage is wide and layered – a perfect blend of the immersion of dynamic models and the precision of planar-magnetic engineering.
The Stock Edition is crafted from Zebrawood, a striking hardwood with bold grain patterns in gold and dark tones. Beyond its visual elegance, Zebrawood brings energy and clarity to the presentation. Paired with coffee-gold grilles and hardware, it creates a distinctly luxurious look.
Included are the new Caldera Pads with a fluted geometry that perfectly balances airflow and pressure. Available in multiple materials, they play a key role in the Caldera’s open, highly resolving signature.
With an 80 mm driver, 65-ohm impedance and ~95 dB/mW sensitivity, Caldera works beautifully across many setups, yet scales at its best with powerful, high-resolution amplifiers.
Caldera is more than a planar headphone – it’s ZMF’s interpretation: dynamic, physical and musical. If you’re looking for a true endgame planar, this is the answer.
