Equipped with a custom 60mm large-diameter dynamic driver, the diaphragm utilizes a composite structure combining a blue nickel alloy dome with a PET surround. The blue nickel alloy gives the diaphragm excellent rigidity and transient response, delivering stable, powerful, and dynamic bass; the PET surround ensures delicate, smooth, and transparent mid-to-high frequencies without harshness. This balanced design combines the power of nickel alloy with the warmth of PET. The large 60mm driver moves ample airflow, creating a soundstage as expansive as Chang'an in the Tang Dynasty—grand yet detailed, with every sound feeling like a magnificent chapter in a glorious era, utterly captivating.
