Shuoer H27 EQ settings
Parametric EQ correction for the Shuoer H27, derived from measurements by crinacle. It moves the measured frequency response toward a neutral target.
How the H27 sounds before EQ
Measured against a neutral target, the H27 comes out bright. Treble sits ahead of the bass, which reads as detail at first and fatigue over time.
The lower mids region, warmth and the body of voices, sits about 3.4 dB behind neutral, so voices lose body and sound hollow. The presence region, vocal clarity and attack, sits about 3.1 dB forward of neutral, so consonants and attack can turn sharp. The bass region, punch and bass lines, sits about 1.7 dB behind neutral, so bass lines sound thin. The air region, openness at the very top, sits about 1.6 dB behind neutral, so the very top closes in (measurements this high up vary between test rigs, so treat the exact number loosely).
The largest deviation runs to about 3.4 dB, which is impossible to miss. This model benefits clearly from correction.
These figures are read from the correction itself: whatever the EQ lifts, the headphone lacked, and whatever it cuts, the headphone had too much of. The target is the community's neutral reference, and how far above 10 kHz you can trust any measurement varies by rig. More bright models.
The correction curve
The solid line is the full measured correction (all 10 filters). The dashed line is what Atrium applies: the same shape at 65 percent strength, capped at 6 dB per band, so the headphone keeps its own character instead of being forced flat.
What the EQ fixes
The biggest moves in this correction, and what they do:
- The filter at 1.83 kHz cuts the vocal presence region by 6.0 dB with a narrow band (Q 2.54).
- The filter at 5.66 kHz cuts the sibilance range by 5.4 dB with a medium-width band (Q 1.43).
- The filter at 454 Hz lifts the lower mids by 4.3 dB with a broad band (Q 0.79).
The preamp of -4.3 dB offsets the boosts so nothing clips at full volume.

This is the full measured correction in AutoEq format. It pastes straight into Equalizer APO or Peace on Windows, and into most parametric EQ apps.
How to use these settings
Manually: enter the preamp and each filter into any parametric EQ. On Windows that is usually Equalizer APO with the Peace interface. On a Mac, eqMac or SoundSource. Set the type, frequency, gain and Q exactly as listed.
With Atrium: pick your H27 in the app and it applies a tuned version of this correction: 65 percent strength with a 6 dB per-band cap, which fixes the rough spots without erasing what the headphone does well. Atrium also measures how you hear with a short listening test and layers your personal hearing profile on top. Two people with the same headphones do not hear the same sound. Headphone corrections are part of Signature Edition; the app itself is free.
H27 vs other Shuoer models
Bass and treble are each model's average distance from the neutral target in that range. Positive means more than neutral, negative means less.
| Model | Signature | Bass vs neutral | Treble vs neutral |
|---|---|---|---|
| H27 (this page) | bright | -0.5 dB | +2.3 dB |
| Aoshida E20 (wide bore eartips) | near-neutral | +0.0 dB | +0.9 dB |
| Cadenza | warm | +0.3 dB | -0.7 dB |
| Cadenza 12 | warm | +1.2 dB | -1.4 dB |
| Cadenza 12 2024 | warm | -0.2 dB | -1.9 dB |
