HIFIMAN HE-R9

Elegance Outside, Strength Inside

The exterior of the headband is covered by high-quality leather, giving it a soft and elegant appearance, with high grade memory foam to achieve the most comfortable fit and elasticity. Its structure is made of solid steel and is both lightweight and strong, yet robust and delicate. Large crimson red ear cups, which have plenty of internal space, help produce spatial cues and provide necessary breathing room for the power driver to sound its best.

The drivers contain a rare earth metal magnet for high sensitivities and a special nanoparticle coating which is applied to their surface. This results in a more natural and detailed sound with a high frequency response up to 35kHz. The idea behind this new technology was inspired by Dr. Fang Bian's Ph.D. thesis, stating that "different nano-materials have differing structures and each of those materials have their own properties." Therefore, by carefully controlling the diaphragm surface structure, you can yield different results in acoustic performance to a degree previously unobtainable.
