Letshuoer S15
The S15 is Letshuoer's 3rd-generation 14.8mm planar with a passive 6mm R-Sonic filter, and approved coverage agrees it deliberately walks away from the bright, energetic S12 formula. The consensus is a rich, smooth, warm-leaning planar that prioritizes body and listenability over raw detail: bass has real weight for a planar, mids are full and relaxed, and treble stays polite. Reviewers praise it as a fatigue-free long-session set, while the recurring criticism is that resolution and clarity are only moderate for $329 and listeners expecting an S12 successor's energy find it subdued.
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.
