HiFiMan RE2000 Earbud Headphones

"Sets a Standard to Aspire To"

HiFiMAN's new RE2000 Reference In-Ear Monitor (IEM) is the company's best IEM ever, and that's saying a great deal. The revolutionary RE2000 utilizes breakthrough nanotechnology called the Topology Diaphragm, delivering smoother, more extended response compared to conventional IEM designs, along with reduced distortion and an improved soundstage for a more realistic listening experience.

"There is something very special about the RE2000," raves earphonia.com, July 14, 2017. "The definition, clarity and extremely well balanced coherence really astounds with its musicality, making it very hard to put down. Currently the RE2000 IEM is amongst one of the preferred of all the flagship earphones we at earphonia.com have ever experienced. HifiMAN have really raised the bar and set a standard to aspire to."

The Challenge of a Dynamic Diaphragm

The dynamic driver in a conventional in-ear headphone can, and often does, produce distortions in operation. These distortions can produce frequency response alterations due to distortion and vibration across the surface of the diaphragm as a result of multiple wave reflection and diffraction.

HiFiMAN engineers set out to control these unwanted and uncontrolled diaphragm distortions by utilizing their extensive expertise in nanotechnology. The result is a Topology Diaphragm that achieves superior control with drastically reduced distortion. You've never heard how good an IEM can sound until you've experiences the RE2000.

The Revolutionary Topology Diaphragm

The RE2000's Topology Diaphragm refers to a revolutionary diaphragm with a special nano particle coating applied to its surface. The idea behind the Topology Diaphragm was inspired by HiFiMAN founder Dr. Fang Bian's thesis that "different nano materials have differing structures, and each of these materials has its own properties." By carefully controlling the diaphragm surface structure, you can achieve results in acoustic performance to a previously unobtainable degree.

The distribution of this nano particle coating adheres to distinct geometric patterns. By varying the surface pattern, the compound used, and the particle thickness, the sound wave can be beneficially manipulated to achieve the desired audio effect and control. The sound waves encounter the listener's ears precisely as the recording engineer intended.

Remarkable Performance

Using a 9.2mm dynamic driver in a rigid gold-plated, brass housing, the RE2000 has a frequency response of 5 Hz to 20 kHz, sensitivity of 103dB, and an impedance of 60 ohms. The detachable cable is comprised of silver coated crystalline copper wire.

Radical Comfort, Too

The unique shape of the RE2000's housing blends industrial design, comfort, and striking good looks. Providing an excellent fit for remarkable comfort and isolation, the RE2000 allows the listener to enjoy music listening for hours on end without the fatigue typical of headphone listening in general and IEMs in particular.

"...I think the RE2000 is deservedly up there as a TOTL IEM on its own merits and it will be very interesting to see how much further Fang can push his Topology driver concept either trickling down into mid-range IEMs or even higher-up."
