Two-Hand Feel Structure: Shape the HIFI sound with a consistent hard hand feel. By replacing spacers, you can adjust the hard & soft elastic hand feel. Includes built-in silicone and ABS spacers for a dual experience. Open Cavity Design: Unlike conventional keyboards, the NA87 MAG modifies the internal cavity to allow sound to break out, enhancing the cavity sound from the root and shaping the "treble powerhouse" of HIFI keyboards. Three-Dimensional Game Liner Architecture: Concentrates sound for each key position through a chessboard-formatted single-key closed structure with a stereo casing. The PCB features multi-layer sound dampening measures for maximum stereo sound optimization. Millisecond Trigger Speed: IROK's new Legendspeed transmission technology is 5x faster than conventional keyboards, ensuring victory through speed. Utilizing Hall effect trigger technology eliminates the limitations of physical triggers in traditional mechanical switches, allowing for faster and more accurate triggering. Full Key Hot-Swap: The NA87 MAG supports hot-swappable magnetic switches for Geonworks Raptor switches and other magnetic switches, enabling users to install different types of switches according to their personal preferences. Exclusive Elemental Style Design: One side of the keyboard features color-coded keys with ultra-high precision IROK new generation custom satellite switches on the larger keys. The other side is designed with IROK's exclusive elemental style to create a dual texture feel.
