EarFun EH100 (red ring) EQ settings
Parametric EQ correction for the EarFun EH100 (red ring), derived from measurements by DHRME. It moves the measured frequency response toward a neutral target.
How the EH100 (red ring) sounds before EQ
Measured against a neutral target, the EH100 (red ring) comes out bass-heavy. The low end dominates the tuning and can mask the mids.
The bass region, punch and bass lines, sits about 3.7 dB forward of neutral, so bass lines carry extra weight. The sub-bass region, rumble and the weight under kick drums, sits about 3.4 dB forward of neutral, so kick drums carry extra weight and rumble. The mids region, vocals and most instruments, sits about 3.1 dB behind neutral, so vocals sit behind the instruments. The presence region, vocal clarity and attack, sits about 1.4 dB forward of neutral, so consonants and attack can turn sharp.
The largest deviation runs to about 3.7 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 bass-heavy 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 4.63 kHz cuts the sibilance range by 4.5 dB with a narrow band (Q 3.18).
- The filter at 178 Hz cuts the upper bass by 4.4 dB with a broad band (Q 0.78).
- The filter at 935 Hz lifts the middle of the mids by 4.2 dB with a broad band (Q 0.60).
The preamp of -4.0 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 EH100 (red ring) 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.
EH100 (red ring) vs other EarFun 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.

| Air 2 NC | warm | +1.2 dB | +0.0 dB |
| Air Pro | V-shaped | +2.0 dB | +1.6 dB |
| Air Pro 2 (2021) | V-shaped | +2.2 dB | +2.5 dB |
| Air Pro 3 | V-shaped | +3.6 dB | +1.6 dB |
