The best open-back headphones strive to break free from the headbands and earcups that bind them. Engineering to emulate the natural listening experience—where sound reaches your ears through the open air, from a source right in front of you—our Axel Grell-designed OAE1 signature Headphones took a step closer to that freedom. Naturally, they sold out fast. Now they’re back in all-black version with the exact same acoustic design. Meet the Drop + grell OAE1: a groundbreaking pair of headphones with game-changing driver geometry and an ultra-expansive soundstage.
