ThieAudio Hype 4 vs Truthear Hexa

ThieAudio Hype 4

The Hype 4 is a $399 hybrid built around a pair of 10mm dynamic drivers working together on sub-bass under ThieAudio's IMPACT2 arrangement, with four Sonion balanced armatures covering mids and highs. Coverage settles on a warm-neutral all-rounder. The low end stays powerful and clean without bleeding into the midrange, the midrange has natural timbre and gives instruments realistic weight and body, and the treble carries detail and air without sharpness, harshness or shoutiness. That last point is why long sessions and poorly mastered tracks get described as easy going. Imaging precision is well regarded, though how exceptional the staging is depends on the account: one calls the stage impressively wide and holographic with imaging among the best at the price, another calls it adequately wide with decent depth and a step behind the pricier Hype 10. Bass impact is the sharper split, read as substantial and weighty in one account and as enjoyable but not hard-hitting in another, which warns dedicated bassheads outright. The recurring complaints concern the box rather than the sound: a 3.5mm-only cable with no balanced or modular option at this price, and a tip selection thin enough that the wider than average nozzle makes tip rolling close to necessary. A dongle or a phone drives it, but source character still matters, since a bright source can push it toward sharpness and a warm one can thicken it.

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.
