HiFiMAN HE-R10D Dynamic Closed-Back Headphones (Black/Wood)

The HE-R10D features large pinewood earcups which enhance the headphone's sonic capabilities. The wooden earcup's large internal space brings sufficient volume and "breathing room" to the driver. TOPOLOGY DIAPHRAGM The Topology Diaphragm refers to a diaphragm featuring a special Nano particle coating applied to its surface. The result is a natural and detailed sound. The idea behind the new Topology Diaphragm was inspired by Dr. Fang Bian's Ph.D thesis which stated that "differing Nano materials have differing structures and each of those materials have its own properties." Therefore by carefully controlling the diaphragm surface structure, you can yield different results in acoustic performance to a degree previously unobtainable. 50MM DYNAMIC DRIVER HIFIMAN uses rare earth magnets in addition to the Topology Diaphragm to provide high sensitivity and detailed response up to 30kHz. CABLES The HE-R10D package includes three detachable cables with three different jacks: 3.5mm unbalanced (1.5m length) XLR balanced (3m length) 6.35mm unbalanced (3m length) TECHNICAL SPECS Frequency Response: 15Hz-35kHz Impedance : 32?
