Reviews last updated: November 2026 · How we calculate this

What customers like about Brainwavz B400

  • Excellent midrange performance with highly detailed and forward-sounding vocals.
  • Comfortable, lightweight ergonomic design resulting from 3D-printed resin shells.
  • Smooth, non-fatiguing sound signature suitable for long listening sessions.
  • Rich accessory package including a hard case, multiple silicone tips, and Comply foam tips.
  • Detachable MMCX cables for easy replacement and improved longevity.
  • Impressive holographic and natural soundstage with precise instrument placement.
  • High value for money compared to other quad-driver balanced armature earphones.

What customers don't like about Brainwavz B400

  • Bass lacks visceral 'punch' or deep sub-bass rumble preferred by some listeners.
  • Reported durability issues, specifically regarding the fragile 3D-printed shells and driver failure.
  • Treble is slightly rolled off and may lack the 'sparkle' desired by some audiophiles.
  • Cables are prone to tangling and can be difficult to detach from the MMCX connectors.
  • Warm sound signature can occasionally make certain tracks sound 'thick' or 'stuffy'.
  • Minor aesthetic inconsistencies in the 3D-printed finish (e.g., uneven transparency).

Verdict

The Brainwavz B400 is a high-performance in-ear monitor featuring a unique 3D-printed liquid resin housing and a quad balanced armature driver configuration (one high, two mids, one bass). It delivers a smooth, natural sound signature with technical specifications including a frequency response of 10Hz to 40kHz, 30Ω impedance, and 115dB sensitivity. Main pros include its exceptional midrange clarity, comfortable ergonomic fit for long sessions, and a generous accessory package featuring detachable MMCX cables. Notable cons include a slight lack of sub-bass punch compared to dynamic drivers and a plastic shell finish that some users find less premium.
