Custom IEM with a Universal Fit with Topology Diaphragm
By controlling unwanted distortion and vibration, our Topology driver provides clearer, more lifelike sound.
The Topology Driver
HiFIMAN's utilization of advanced depositional technology and research makes for a driver unlike any other in the world. With the creation of Topological, Nano scale layer application technology, upon a driver diaphragm, allows for the manipulation of sound wave creation like never before. No other driver technology allows for such control and precision resulting in clarity, detail and nuance.
What is a Topology Diaphragm?
  The "Topology Diaphragm" or "Topology Driver" refers to the diaphragm with a 
  special Nano particle coating applied to its surface. The distribution of the coating 
  has distinct geometric patterns. By varying the surface pattern, compound used,
  the thickness or geometric pattern sound wave formation can be manipulated to
  achieve the desired audio effect and control. 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.
Armature's Inadequacies
  The inadequate soundstaging produced by
  Armatures is caused by the way sound
  waves are formed by armature's multiple wave 
  reflection and diffraction in the driver, which can
  cause high levels of distortion. Therefore,
  armature based IEMs have little breadth and yield
a sound flat and without emotion.
 The Diaphragm Distortions of Dynamic Drivers
  Traditional dynamic drivers can produce
  response alteration due to
  distortion and vibration across the
diaphragm surface.
The Ideal 
  Dynamic Driver
  The Topology diaphragm structure used by
  HIFIMAN greatly reduces the uncontrolled
  diaphragm distortions, enabling the
  operational performance of dynamic IEM's
  to an approach to an ever superior, trend
towards perfect wave control.
The Perfect Blend of Acoustic Drama and Clarity
The creation of countless prototypes and user testing combined with the Topological driver pattern changes mean your ear encounters the sound wave precisely as the original recording creator intended.
Radical New Housing for a Radical New Driver
  The shape of the housing is again an example of blending industrial design, comfort
  and a striking visual. Providing excellent fit, comfort and isolates, all to give you the
  most wonderful of listening experiences.
