Beyerdynamic DTX 350p EQ settings
Parametric EQ correction for the Beyerdynamic DTX 350p, derived from measurements by oratory1990. It moves the measured frequency response toward a neutral target.
How the DTX 350p sounds before EQ
Measured against a neutral target, the DTX 350p comes out warm. The low end sits ahead of the treble, which flatters bad recordings and rounds off detail.
The air region, openness at the very top, sits about 3.9 dB forward of neutral, so the very top sounds airy and open (measurements this high up vary between test rigs, so treat the exact number loosely). The treble region, cymbals, sibilance and sparkle, sits about 2.5 dB forward of neutral, so cymbals and s-sounds can sting. The bass region, punch and bass lines, sits about 2.1 dB forward of neutral, so bass lines carry extra weight. The lower mids region, warmth and the body of voices, sits about 2.1 dB behind neutral, so voices lose body and sound hollow.
The deviations are moderate, topping out around 2.5 dB, which is clearly audible in a direct comparison. EQ makes a worthwhile difference.
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 warm 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 103 Hz cuts the bass punch region by 5.0 dB with a medium-width band (Q 2.23).
- The filter at 352 Hz lifts the lower mids by 4.4 dB with a medium-width band (Q 1.40).
- The filter at 1 kHz cuts the air band by 4.1 dB with a shelf.
The preamp of -4.1 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 DTX 350p 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.
DTX 350p vs other Beyerdynamic 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 |
|---|---|---|---|
| DTX 350p (this page) | warm | +2.0 dB | +0.9 dB |
| DT 770 Pro | warm | +1.5 dB | +0.3 dB |
| DT 880 | bass-light | -2.7 dB | -0.4 dB |
| DT 900 Pro X | bass-light | -3.5 dB | +0.4 dB |
| Amiron 100 (eq off) | near-neutral | +0.8 dB | -0.0 dB |
