The ZMF Atrium Open - Redwood Burl LTD is a limited-edition flagship open-back headphone featuring rare, old-growth California Redwood Burl (Sequoia sempervirens) earcups. Formed over centuries, each earcup displays an organic arrangement of lacy swirling eyes, mineral deposits, and rich color shifts ranging from deep crimson and burgundy to warm amber. Accented with an anodized black aluminum chassis, black grille and rods, and a custom maroon grille cloth, the Redwood Burl LTD blends acoustic engineering with one-of-a-kind visual craftsmanship.
At the core of the Atrium Open is ZMF’s proprietary 300-ohm Biocellulose N52 dynamic driver paired with the Atrium Damping System. This acoustic damping network regulates air pressure within the wooden cup volume, yielding an expansive, three-dimensional soundstage with deep bass extension, natural midrange timbre, and smooth high-frequency detail. Weighing approximately 490g and backed by ZMF's lifetime driver warranty, each unit comes complete with two pairs of leather or suede pads, a stock braided cable, and a rugged Seahorse protective flight case.
