HiFiMAN RE2000 – Amazing – Ample – Absolute


Build Quality/Aesthetics/Fit


HiFiMAN RE2000 is a unique technical and technological accomplishment, state-of-the-art IEM which relies on cutting edge technology developed especially for them (The Topology Driver). Physically, they are on the larger size, to allow enough space for the rather large 9.2mm Topology driver. Despite their rather large size, the fit and ergonomics are quite excellent. RE2000 relies on a shallow insertion fit, has a vented design (presents no driver flex), and they have an ergonomic body without any acute angles or edges, featuring a smooth body that can sit comfortably in one’s ears for hours in a row.
The Topology driver is a unique technology developed by Dr. Fang Bian after years of research and tryouts with unique and independently-developed material coatings along with a series of patterns that ensure the best sound possible for their drivers. In all fairness, the sound of RE2000 is surely influenced by this technology and it has proved to bear a rather unique signature.


The build quality is excellent, RE2000 being built from one gold piece and a black plastic plate that bears the logo of HiFiMAN. The bores are normal sized and they feature a metal grille to protect the driver inside from dust and other debris. The cable connectors are made out of hard plastic, and they are designed with the pins on the cable, providing a guide for proper cable insertion.


After almost three months of usage, RE2000 feels and looks exactly as they did the first day I saw them, being some of the highest quality IEMs when it comes to their resilience.


RE2000 can be driven from virtually any source, being quite efficient and having an average impedance, but they sound much better when driven from higher quality sources (FiiO X7mkii, iBasso DX200, Opus #2, iDSD BL, etc.), scaling well with higher quality sources.


RE2000 can be used outdoors, isolating quite well from the ambient noise and providing great comfort while walking or doing other activities, being some of the IEMs I grab most often when going outside.
