Detail
Planar magnetic headphones are a type of high-fidelity headphones that use flat diaphragm technology. Unlike traditional dynamic or balanced armature headphones, planar headphones utilize an ultra-thin diaphragm evenly driven by a magnetic field. This allows them to produce sound with greater accuracy, lower distortion, and richer detail. Such design delivers exceptional layering and realism, providing a purer, more natural listening experience.
The ultra-thin diaphragm, crafted with nano-level precision, delivers faster response, enhanced detail, and a more natural, clear, and layered sound.
Utilizing advanced targeted sputtering technology, a highly conductive silver metal voice coil as thin as 1.3μm is precisely coated onto the diaphragm. This process significantly enhances sound refinement while ensuring durability, keeping excellent audio performance consistently stable over time.
Each driver unit features 22 pieces of N50-grade neodymium magnets arranged symmetrically, ensuring precise and stable diaphragm vibration. This design enables accurate and swift dynamic response, effectively reducing nonlinear distortion to produce purer, more natural sound, faithfully reproducing the essence of music.
The high-transparency rigid rear mesh structure provides stable air pressure damping and linear feedback. It smooths out frequency spikes and reduces nonlinearity, achieving an open, airy soundstage with ultra-low acoustic resistance.
Allows seamless vertical and horizontal rotation for a custom fit to different head shapes, enhancing both comfort and stability.
The headband features a silicone adjustment slider with a damped, smooth feel, enabling easy and precise positioning based on personal preference.
Made of high-strength memory metal, the headband maintains its shape over time. Lightweight and flexible, it reduces pressure and enhances comfort.
Crafted with perforated leather and breathable fabric, the earpads stay cool and soft. Memory foam inside ensures all-day comfort without overheating.
