Grado SR 125X
The SR125x model benefits from GRADO’s ability to combine very light materials with extreme stiffness and the best cushioning properties.
The SR125 is based on the same technology as the SR80x model, but has improved diaphragms and voice coils. The latter are also made of ultra-pure, large-crystal copper (UHPLC=Ultra High Purity Long Crystal).
The membranes go through a special material relaxation process, which benefits the inner reproduction of details. Basses, mids and trebles sound more open overall.
