Verdict

The Hifiman RE400 is a wired in-ear monitor (IEM) featuring custom 8.5mm titanium-coated dynamic drivers with neodymium magnets, housed in a compact CNC-machined aluminum shell. It offers a frequency response of 15Hz–22kHz, 32-ohm impedance, and a sensitivity of 102dB, making it easy to drive with portable devices. Characterized by a neutral and smooth sound signature with a slight mid-centric warmth, it is highly praised for its exceptional clarity, precise imaging, and lightweight ergonomic fit suitable for long listening sessions. However, its main drawbacks include a non-detachable cable often noted for durability issues, a relatively small soundstage, and a lack of in-line controls or a microphone.

What customers like about HiFiMAN RE400?

  • Neutral and well-balanced sound signature ideal for reference listening.
  • Exceptional midrange clarity, especially for female vocals and acoustic instruments.
  • Extremely lightweight and compact design, providing high comfort for long listening sessions or sleeping.
  • Outstanding value for the price, frequently cited as one of the best budget audiophile options.
  • Effective noise isolation when used with a deep-sealing ear tip.
  • Rich accessory set including multiple styles of silicone tips and replacement filters.

What customers dislike about HiFiMAN RE400?

  • Fragile build quality, with numerous reports of the non-detachable cable cracking or breaking over time.
  • Bass response is lean and lacks the deep sub-bass impact preferred by 'bassheads'.
  • Non-detachable cable makes it impossible to replace if damaged, which is a major long-term reliability concern.
  • Cable noise (microphonics) can be distracting when the wire rubs against clothing.
  • Treble extension is somewhat limited, leading to a 'rolled-off' sound in the high frequencies.
  • Small soundstage width compared to some newer competitors in the same price bracket.
