ZMF Caldera Closed Headphone
Planar performance meets true isolation
The Caldera Closed is ZMF’s first fully closed-back planar headphone. Based on the acclaimed Caldera Open, it delivers fast, lively sound with added isolation and deeper bass. This model earned the Headfonics Best Ortho 2023 award, highlighting its innovation and quality.
Signature sound, closed-back control
This headphone includes ZMF’s patented Atrium Damping System, along with the Caldera Magnet System and custom Caldera Pads. These features work together to produce detailed, dynamic sound with great balance and depth.
Compared to the open version, the Caldera Closed adds a sub-bass boost. It also leans closer to a Harman-style tuning for a smooth, natural sound. At the same time, it preserves ZMF’s musical and engaging character.
Unique shape, comfortable feel
The Caldera closed debuts a new cup shape inspired by a volcanic caldera. Its flowing curves are not only eye-catching, but also help reduce weight. As a result, the headphones feel lighter and more comfortable than they appear.
Each pair features Shou Sugi Ban Ash—a European ash wood treated with a Japanese charring technique. This finish brings out the wood grain and gives each cup a bold, textured look.
