Review by ljokerl: HiFiMAN RE-400.
Value (10/10) - The latest iteration of the balanced-and-accurate dynamic-driver earphone from HiFiMan, the RE-400 offers an audible tuning change from the old RE0 and RE-ZERO models. It produces slightly weightier bass, a more well-rounded presentation, and smooth, forgiving treble while still offering accuracy on a level very rarely found at or near its price point.
Additional improvements over the previous-gen RE-ZERO include a more robust construction and better noise isolation, mostly due to the more compact, deep-sealing form factor. The RE-400 also boasts much nicer packaging, though there is still a disappointing dearth of accessories. The no-frills approach is fine by me - the RE-400, like its predecessors, is a listener's IEM. All in all, adding a hint of warmth to an otherwise neutral sound should let RE-400 appeal to the casual listener better than the models it replaces while holding very close to the HiFiMan sound many—myself included—have come to love.
