Quick Read

Thieaudio Monarch MKIII

The Monarch MKIII kept ThieAudio's kilobuck crown relevant: a $999 tribrid whose consensus reputation is built on exceptional spatial imaging and superbly textured, balanced delivery. Headfonics rates it an excellent multi-driver IEM with power, clear vocals, and very resolving staging; MajorHiFi hears the series' best refinement yet, with placement more concise than any prior Monarch and one of the best thousand-dollar packages overall: comfort, design, and stock cable included. The debates that follow it: the MKII remains on sale at the same price with a different (warmer) signature, unit fit is large-ish, and the energetic top end rewards clean sources.

Truthear Hexa

The Truthear Hexa is a hybrid in-ear monitor pairing a 10mm dynamic driver with three balanced armatures, sold at about $79.99 with a detachable 0.78mm 2-pin cable and a 3.5mm plug. The tuning sits at or near neutral rather than V-shaped, and a measurement-led review found the frequency response remarkably similar to that publication's own preference curve. The midrange is the most consistently praised region: vocals are described as clear, natural and transparent, though some listeners hear less life in them than they want. Resolution and instrument separation are called strong points for the price, while imaging is rated only average and can sound congested on busy passages. Opinion divides at both ends of the spectrum. The low end draws complaints that mid-bass is subdued and that the default balance wants more bass, yet another listener reports solid depth, body and impact from the dynamic driver. Treble divides the same way: some hear a deliberately safe, softened top with no glimmer or sparkle, while others point to an audible peak near 8 kHz that adds airiness, and to excess energy in the highs relative to a preference curve. Lower treble is described as dipped or rolled off. Stage width is the clearest shared limitation, called narrow, intimate and somewhat closed in. Shells are light 3D-printed resin with anodized aluminum faceplates, and comfort over long sessions is a recurring highlight. There is no microphone and no IP water resistance rating.

Strengths

  • Exceptional spatial imaging and resolving, layered staging
  • Superbly textured, balanced tuning across the spectrum
  • Complete kilobuck package: comfort, design, and quality stock cable

Weaknesses

  • MKII coexists at the same price with a different signature, complicating choice
  • Larger shells demand fit tolerance
  • Energetic treble rewards, and punishes, source quality

The Truthear Hexa is a hybrid in-ear monitor pairing a 10mm dynamic driver with three balanced armatures, sold at about $79.99 with a detachable 0.78mm 2-pin cable and a 3.5mm plug. The tuning sits at or near neutral rather than V-shaped, and a measurement-led review found the frequency response remarkably similar to that publication's own preference curve.

Treble divides the same way: some hear a deliberately safe, softened top with no glimmer or sparkle, while others point to an audible peak near 8 kHz that adds airiness, and to excess energy in the highs relative to a preference curve. Lower treble is described as dipped or rolled off. Stage width is the clearest shared limitation, called narrow, intimate and somewhat closed in. Shells are light 3D-printed resin with anodized aluminum faceplates, and comfort over long sessions is a recurring highlight. There is no microphone and no IP water resistance rating.

Strengths

  • Neutral-leaning tuning that tracks a published preference curve closely and stays free of sibilance or sharpness over long sessions
  • Midrange and vocals read clear, natural and transparent, and are the most consistently praised part of the sound
  • Resolution and instrument separation are called strong points for the price, edging out a same-price single dynamic on detail
  • Light 3D-printed resin shells with anodized aluminum faceplates that stay comfortable for hours of listening
  • Detachable 0.78mm 2-pin cable, six pairs of silicone tips, foam tips and a carrying case included at a budget price
  • Takes EQ readily: a single high-shelf cut above 1 kHz is offered as the fix for the light low end

Weaknesses

  • Mid-bass is subdued and the default balance leaves listeners wanting more low end, with the overall tuning called slightly thin
  • Stage width is narrow and the presentation is intimate and somewhat closed in
  • Imaging is rated only average for the class and can sound congested on busy passages
  • Treble is polarizing: some hear a safe, sparkle-free top while others hear a peak near 8 kHz, so upper-treble tolerance decides the fit
  • Lower treble is dipped or rolled off, which darkens the midrange slightly and costs instrument tails some bite
  • No microphone and no IP water resistance rating, it is not a workout fit, and smaller ears are flagged as a fit problem
