Quick Read

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.

ThieAudio Hype 2

The Hype 2 is the entry point of ThieAudio's Hype line, a quad-driver hybrid pairing two 10mm dynamic drivers in an isobaric arrangement with two Sonion balanced armatures. The most consistent praise goes to the low end: sub-bass reaches deep with genuine rumble and stays disciplined rather than bleeding or bloating into the midrange. The treble is the other settled point, tuned smooth and free of sibilance or peaky edges, with an audible roll-off that trades sparkle for comfort. Almost everything else is contested. The tonal reading ranges from bold, warm and bass-led to essentially neutral and slightly dark with linear bass that favors texture and body over punch. The midrange draws the sharpest split: one reading finds a veil over female vocals and dynamics that drop unpredictably into the background, producing a disjointed effect, while others hear clean, natural mids with vocals placed either forward or seated inside a warm mix. Technical performance splits along the same line, described on one hand as average staging with a small soundstage and detail below what a multi-driver set should give, and on the other as a wide, open stage with excellent separation and generally very high detail. Build is the least contested area: the 3D-printed resin shells show no manufacturing flaws, the accessory bundle is complete, passive isolation is strong, and the shells are large enough that fit is the main practical risk for smaller ears.

Strengths

  • Rich, smooth, non-fatiguing tuning that is rare among planar IEMs
  • Bass carries genuine weight and warmth without losing planar control
  • Comfortable long-session listen with a full-bodied midrange

Weaknesses

  • Detail and clarity are moderate for the $329 asking price
  • Polite treble and relaxed presentation can read as dull after the S12
  • Not the pick for listeners chasing maximum technical performance

Build is the least contested area: the 3D-printed resin shells show no manufacturing flaws, the accessory bundle is complete, passive isolation is strong, and the shells are large enough that fit is the main practical risk for smaller ears.

Strengths

  • Deep sub-bass with genuine rumble and texture that stays disciplined instead of bleeding or bloating into the midrange
  • Smooth treble with no sibilance, no harshness and no peaky edges, which supports long sessions without fatigue
  • Excellent 3D-printed resin construction with no visible manufacturing flaws and shells that are very light in hand
  • Complete bundle: three sizes each of foam and silicone tips, a silver-plated cable, a cloth and a case or pouch
  • Strong passive isolation, helped by the large shell, which keeps outside noise out on commutes
  • Efficient at a rated 25 ohms and 108dB/Vrms, so a phone or a basic dongle drives it without a separate amp

Weaknesses

  • Some listening finds a veil over female vocals plus dynamics that drop unpredictably, making the presentation sound disjointed
  • Drum and cymbal timbre can read as artificial, without convincing attack
  • Detail retrieval is disputed, and by one account falls short of what a four-driver hybrid at this price should give
  • The top end rolls off, so sparkle and shimmer are moderated; listeners who want treble bite should audition first
  • Comfort is ear-size dependent: the oversized shell can turn uncomfortable for smaller ears over long sessions
  • The $219 Kiwi Ears Quintet and $219 Simgot EA1000 compete closely, which squeezes the value case
