It's boring. So boring, like mega boring to the max.
Youtube Video Summary

Build & accessories: understated box, a surprisingly nice cable with a “juicy” feel and flat 2-pin connectors, plus extra filters. The stock tips are the weak link—thin out note weight and feel downright horrific, so a tip swap is recommended. The medium-to-large shell is a highlight: secure fit, comfy nozzle size, and a handsome faceplate that looks premium in ear. Overall ergonomics and finish scream daily-driver friendly.

Sound: impactful, well-judged bass, lively upper mids, and a touch of upper-air jank; for $200 it’s a strong value with a clean, modern JM1-style tuning. Easily the most convincing Kiwi Ears to date: more balanced and natural than Quintet (which pushes upper mids/10 kHz energy), far more sensible than the treble-shouty Forteza, a clear upgrade over budget options like DLS and the tiny, poorly packaged Singolo, and less fatiguing than the bass-and-upper-mid heavy Melody. Against $200 benchmarks, KE4 becomes a new reference—cleaner male vocals and better build than “Chopin,” and a tighter low end plus tidier mids than AFUL Performer 5. Trades blows with Hype 4 at a fraction of the price; those craving a pricier step-up in the same vein can eye HiSenior Mega5EST. Measured verdict: Tier A, 3-star, 8.8 for tone—good imaging, solid soundstage, gamer-friendly, not flawless but genuinely excellent once re-tipped. A handsome, comfortable set that delivers outstanding value for newcomers and gift-givers alike.

FiiO FH15 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

D+
  • Expect a patchy tonal profile that makes instrumentation feel mismatched. EQ is almost mandatory to tame the response.

Average Technical Grade

E-
  • Instrument separation collapses instantly, burying nuances and leaving everything in a gray blur. Layered arrangements collapse into a messy haze.
Mids C+
It presents a stable midrange foundation suitable for everyday listening. Clarity is serviceable without standing out.
Treble E-
Treble is heavily rolled off, muting sparkle and detail. Detail retrieval in highs is nonexistent.
Dynamics E+
Dynamic range feels limited, smearing micro-contrast and transient attack. Soft details are smoothed into the background.
Soundstage C+
Stage expands beyond the shoulders and finally hints at layers, though vertical cues stay muted. Depth cues begin to emerge.

6.5

Solid pick for the price, if you're after a warm neutral sound.

Pros
Overall very pleasant balance with good tonality and perceived technicalities for the price.
Cons
Bass can come off slightly boomy and a bit disjointed sounding at times, and somewhat relaxed upper mids gives a perception of bluntness to the sound, most evident on snare and other percussive strikes.
