HEDDphone TWO: The New Open-Back Reference in the HEDD Audio Range
Designed in Berlin by HEDD Audio, the HEDDphone TWO succeeds the HEDDphone ONE with a clearly "high-end studio" oriented approach. After more than three years of development, the brand didn't settle for a simple tweak: the transducer was redesigned from scratch and the architecture optimized to gain in compactness, durability, and comfort. The result: a premium open-back headphone, designed to meet the expectations of demanding users, from mixing to mastering, while maintaining a spacious and "speaker-like" listening experience.Who Is the HEDDphone TWO For?
The HEDDphone TWO is primarily aimed at mastering engineers, mixers, and producers seeking a monitoring headphone capable of revealing micro-details (attacks, textures, reverbs, fine dynamics) without harshness. Its open-back design promotes a wide and airy soundstage, ideal for judging depth and placement, with minimized listening fatigue over time. Like all open-back headphones, it lets sound pass outward: perfect for quiet studios, less suitable for noisy environments or close-miking situations.Technical Specifications
