Introduction

HiFiMAN was one of the first brands to produce high performance in-ears based around a dynamic driver. RE-series in-ears have always provided excellent bang for the buck and are highly touted, even amongst audiophiles. Today, we are taking a look at HiFiMAN's newest RE-series in-ear solution: the RE-400s. The design takes after the RE-0s in some areas through its aluminum housing, but the RE-400s are, other than that, completely new iterations that have been built from the ground up.

Everything from the driver and onward has changed, largely due to the new small diameter dynamic driver that has been in the works for quite some time, and the RE-400s use this completely new 8.5mm dynamic driver. It should perform quite well across the audible spectrum.
