In 2018, HiFiMAN returned to the development of closed-back models, leading to a design breakthrough the following year, introducing the HE-R10D. Now, the HiFiMAN HE-R9 is introduced as a more affordable model. The ear cup’s large internal space brings sufficient volume and “breathing room” to the powerful driver. HiFiMan first developed its closed-back planar headphones in 2012. After several attempts to develop a closed-back headphone worth of the HiFiMan name, the company turned its attention to open-back planar headphones that quickly became some of the most successful products on the market.

HiFiMan Topology Diaphragm

The “Topology Diaphragm” of the HifiMAN HE-R9 BT refers to a diaphragm featuring a special Nano particle coating applied to its surface. The result is a more natural and detailed sound than what is typically achieved in True Wireless earphones. The idea behind the new Topology Diaphragm was inspired by Dr Fang Bian’s Ph.D. thesis that “different 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.


Best-Sounding 50mm Dynamic Driver

  • High sensitivity thanks to HIFIMAN’s use of a rare earth magnet
  • Topology diaphragm for detailed high frequency response to 35kHz
  • Advanced voice coil


Elegance Outside, Strength Inside

The exterior of the headband of the HifiMAN HE-R9 BT is covered in high-quality leather, giving it a soft and elegant appearance. Inside, there is high-grade memory foam, selected to achieve the most comfortable fit and elasticity. The headband skeleton itself is made of solid steel.

The structure is both lightweight and strong, robust yet delicate, and designed to convey detail and musicality that is unmatched in the market.

Large Ear Cups for Superior Acoustics

The crimson red ear cups are large, with internal space that helps produce substantial volume and the necessary breathing room for the powerful driver to sound its best.
