UNIQUE FreeEdge DRIVER TECHNOLOGY. At the heart of the Denon AH-D7200 headphones is that 50 mm FreeEdge driver diaphragm, made from a nano-fibre material chosen for its rigidity and low mass. This delivers an accurate pistonic motion without distortion, and is also self-damping to cancel out unwanted resonances within the diaphragm. REAL WOOD. The beautiful 100% natural walnut ear cups enhance the sound experience. They are self-damping and strong, eliminating unwanted vibrations. ULTRA-HIGH-QUALITY CONNECTION. The Denon AH-D7200 over ear headphones come equipped with a detachable 7N-purity copper cable, made in Japan to Denon’s exacting specification. This ensures the best possible signal transmission and is fitted with a durable machine-cut metal plug with an ornamental copper ring. PERFECT ADJUSTMENT. To accomodate varied head-sizes, the adjustable headband uses positive ball-bearing click-stops for precise and repeatable adjustment. LUXORIOUS FIT. The headband on the Denon AH-D7200 Hi-Fi Headphones deploys perfectly ergonomically contoured diecast aluminum construction for optimized comfort and fit. SUPERIOR COMFORT. The ear-pads are gently wrapped in an extremely soft engineered leather developed specifically for the AH-D7200, and memory foam, allowing them to conform to the shape of your head for the most comfortable fit.
