Why Default Audio Settings Are Costing You Kills
Every competitive FPS ships with audio that sounds good to most players on most headphones. "Good to most" means tuned for a consumer response — punchy bass, hyped treble, scooped mids. That tuning is actively hostile to competitive play.
The problem isn't the game's audio engine. CS2, Valorant, and Apex all model footstep propagation accurately. The audio data is in the signal. The problem is that most headphones are designed to make music sound exciting, not to surface quiet mid-frequency information clearly — and footsteps are quiet mid-frequency information.
The typical consumer headphone applies:
- +4–10 dB bass shelf below 100 Hz (makes explosions feel exciting, drowns out footstep fundamentals)
- -3–6 dB in the 200–600 Hz range (directly attenuates the frequency bands where footsteps live)
- +6–12 dB treble peak at 8–12 kHz (makes high-frequency effects harsh, shifts perceived loudness away from footsteps)
The fix is two steps: correct the headphone response to a neutral baseline, then boost the specific frequency bands where each game's footsteps live. Skip step one and your footstep boost will be fighting your headphone's existing colorations instead of building on neutral ground.
Headphone correction + game-specific boost = precise. Game-specific boost alone on an uncorrected headphone = unpredictable. Always correct first.
CS2: EQ Settings for Competitive Play
CS2 is the most EQ-friendly of the three games. The Source 2 audio engine has a relatively clean footstep signal — impacts are consistent, surface types are predictable (mostly concrete and metal), and the ambient noise floor is low. This makes precise EQ corrections very effective.
CS2 Frequency Zones
| Zone | Frequency | Direction | What It Does |
|---|---|---|---|
| Low rumble | 60–100 Hz | -2 to -3 dB | Reduce bass smear that masks footstep separation at range |
| Footstep fundamental | 200–500 Hz | +4 to +5 dB | Core impact of footsteps — this is where you "hear" someone's weight |
| Step texture | 500–800 Hz | +2 to +3 dB | Surface character — grit, concrete, metal grating |
| Distance cues | 800 Hz–2 kHz | ±1 dB | High-frequency decay tells you how far away the step is |
| Gunshot brightness | 4–8 kHz | -1 to -2 dB | Slightly tame to reduce ear fatigue without losing directionality |
CS2 Surface-Type Audio Differences
CS2 maps predominantly use concrete, tile, and metal surfaces. Here's how each shifts the dominant footstep frequencies:
The baseline in most CS2 maps (Mirage, Inferno, Dust2). Footstep fundamental at 250–400 Hz. Clean transient, easy to separate.
Common on Nuke and Train. More energy in 600–1200 Hz — a brighter "clang" texture that carries at range.
Found on Inferno catwalk, Vertigo. Mid-forward: 300–700 Hz with a slight 1–2 kHz resonance.
Dust2 mid, Mirage courtyard. Softer impact: energy concentrated at 200–350 Hz with fast high-frequency rolloff.
You can't EQ-optimize for every surface type simultaneously — boosting for concrete might make metal grating too loud. Target the predominant surface for the maps you play most. Mirage, Inferno, and Dust2 players: center your boost around 300 Hz. Nuke players: extend the boost to 700 Hz.
Valorant: EQ Settings for Competitive Play
Valorant's audio environment is significantly noisier than CS2's. Ability sounds from agents — Sage's crystalline walls, Brimstone's incendiary smoke, Jett's daggers — cluster in the 1–5 kHz range. This means boosting high-mids helps footsteps but also makes abilities painfully loud. The Valorant EQ strategy is more conservative above 700 Hz.
Valorant Frequency Zones
| Zone | Frequency | Direction | What It Does |
|---|---|---|---|
| Sub-bass | 60–120 Hz | -3 to -4 dB | Ult and ability bass blooms can completely mask quiet footsteps — reduce this |
| Footstep fundamental | 150–450 Hz | +4 to +6 dB | The highest-priority boost for Valorant — footsteps are quieter here than in CS2 |
| Step texture | 450–700 Hz | +2 to +3 dB | Surface differentiation (tile vs. carpet) on Bind, Ascent, etc. |
| Ability overlap zone | 1–4 kHz | -1 to -2 dB | Tame this range to reduce ability-sound loudness without hurting footstep detection |
| Air & presence | 6–10 kHz | ±1 dB | Keep natural; avoid boosting — Killjoy turret and Cypher wire sounds dominate here |
Valorant Surface-Type Audio Differences
Dominant surface in Valorant. Footstep fundamental at 200–400 Hz. Clean, consistent, easy to localize.
Dramatically softer footsteps — fundamental shifts to 150–300 Hz with steep rolloff above 600 Hz. Your boost must hit deeper to compensate.
Gritty, mid-forward texture. Energy at 250–500 Hz. Similar to CS2 outdoor surfaces.
Bright, resonant: 500–1000 Hz dominant. Can bleed into ability-sound territory — be cautious about boosting this high.
Apex Legends: EQ Settings for Competitive Play
Apex has the highest ambient noise floor of the three games. Respawn's audio has historically been criticized for "soup" — a dense mix of environmental sounds, legend abilities, and weapon effects that competes with footsteps. Aggressive EQ boosts here can amplify the ambient noise alongside footsteps, making the mix muddier instead of cleaner.
The Apex strategy: precise, narrow-Q boosts in the low-mid range, with significant low-end reduction to cut through the ambient haze.
Apex Legends Frequency Zones
| Zone | Frequency | Direction | What It Does |
|---|---|---|---|
| Sub-bass / rumble | 40–80 Hz | -4 to -5 dB | Apex has significant ambient sub-bass (storms, environment). Aggressive cut helps separation. |
| Low-mid haze | 100–180 Hz | -1 to -2 dB | Second haze zone — reduces ambient mud before footstep boost |
| Footstep fundamental | 200–450 Hz | +3 to +5 dB | Core footstep zone — keep Q relatively tight (1.4–1.8) to avoid boosting adjacent haze |
| Step texture | 450–650 Hz | +1 to +2 dB | More subtle than CS2/Valorant — terrain variety means texture frequencies vary widely |
| Ability noise floor | 2–6 kHz | -1 to -2 dB | Legend abilities, ziplines, and respawn beacons flood this range — tame it |
Apex Legends Surface-Type Audio Differences
Prevalent on Worlds Edge and Storm Point. Soft, low fundamental at 180–320 Hz — requires the deepest boost.
On buildings and elevated platforms. Bright, resonant: 400–900 Hz. The most audible surface in Apex — often the giveaway for flank routes.
Concrete-type. Fundamental at 250–450 Hz. Reverb from enclosed spaces adds spatial information — don't over-boost or it becomes echo soup.
Unique texture with sub-bass impact and fast treble crunch. 200–350 Hz fundamental with faint 1–2 kHz crunch.
These settings are starting points.

Generate Your EQ Profile →Why One-Size-Fits-All EQ Doesn't Work
The frequency tables above tell you where to boost for each game. But they don't account for what your headphone is already doing to those frequencies before you apply any EQ. This is the fundamental problem with generic gaming EQ presets.
Consider two popular headphones:
- HD 560S: Relatively neutral bass, slight mid-forward presence, modest treble peak around 7 kHz. Bass at 80 Hz is roughly neutral. Mid-bass at 300 Hz is slightly elevated.
- DT 990 Pro: Significant bass shelf boost (+4–6 dB below 150 Hz), neutral-to-slightly-recessed mids (200–800 Hz), and a sharp treble peak at 8 kHz (+8–10 dB).
If you apply the same "+5 dB at 300 Hz" CS2 boost to both:
- On the HD 560S: the boost lands close to a neutral baseline. The 300 Hz range was already roughly flat, so +5 dB is actually +5 dB in perceived loudness. Result: footsteps are noticeably clearer.
- On the DT 990 Pro: the 300 Hz range is already depressed relative to the massive bass shelf. The "+5 dB" partially cancels the existing scoop. You end up with maybe +1–2 dB of actual perceived boost — not enough to make a meaningful difference. Meanwhile the bass shelf is now even louder relative to the footstep range.
The same boost. Completely different results. This is why people say "I tried gaming EQ and it didn't help" — they applied a flat boost to a non-flat headphone and got a non-flat result that wasn't tuned for either purpose.
Equalizer APO applies digital filters to the output signal. It doesn't know or care about your headphone's existing frequency response. A "+5 dB" filter at 300 Hz adds exactly +5 dB to the digital signal. What your ears hear depends on your headphone's driver response at that frequency — which could already be +4 dB or -6 dB relative to reference.
Headphone-Specific EQ Guidance
Here's how the most common gaming headphones behave and what that means for your EQ strategy:
| Headphone | Bass | Mids (footstep zone) | Treble | Correction strategy |
|---|---|---|---|---|
| Sennheiser HD 560S | Slightly lean below 100 Hz | Neutral to slightly forward 300–700 Hz | Modest 7 kHz rise, smooth rolloff | Light correction. Bass shelf +1–2 dB, mild 7 kHz notch. Game boost lands almost as-designed. |
| Beyerdynamic DT 990 Pro | Heavy shelf +5–7 dB <150 Hz | Slightly recessed 200–600 Hz | Harsh peak at 8 kHz (+8–10 dB) | Significant bass cut, mid fill, 8 kHz notch filter. Without correction, game boosts are nearly useless against the bass shelf. |
| HyperX Cloud II | Bass boost +4–6 dB <120 Hz | Presence dip 300–700 Hz (–3 to –5 dB) | Bright with peak 8–10 kHz | Bass cut, significant mid fill (+5–7 dB, 300–600 Hz), treble notch. The mid dip is the main problem for footsteps. |
| Sennheiser HD 599 | Slightly warm, controlled bass | Smooth mids, slight scoop 500–800 Hz | Relaxed treble — very forgiving | Light 500–800 Hz boost covers the scoop. One of the easier headphones to tune for gaming. |
| Audio-Technica ATH-M50x | Elevated +4–5 dB <100 Hz | Balanced 200–600 Hz (good baseline) | Crisp presence peak at 10 kHz | Bass cut primarily. Mids are decent without correction — smaller game-specific boost needed than most. |
| Razer BlackShark V2 | Moderate bass +3–4 dB | Slightly recessed 300–500 Hz | Forward presence and air (6–12 kHz) | Bass cut, mid fill 300–500 Hz (+3–4 dB). Treble is already forward enough for high-frequency cues. |
| SteelSeries Arctis Nova Pro | V-curve: elevated bass shelf | Slight dip 400–700 Hz | Elevated presence 5–10 kHz | Similar to HyperX Cloud II correction path. Mid fill is the priority. |
What About IEMs?
In-ear monitors have fundamentally different acoustic behavior than over-ear headphones. IEM measurements follow the IEC 60318-4 Ear Simulator standard (commonly called the "5128" target after the ear canal simulator). IEMs need significantly more upper-midrange correction — typically +3–5 dB in the 3–8 kHz range — because the ear canal resonance behaves differently with in-canal transducers.
For IEM gaming EQ, the footstep boost frequencies are the same (200–700 Hz), but the correction baseline looks very different. Using over-ear correction profiles on IEMs will leave you with harsh treble and over-bright ability sounds. StepFreq uses Crinacle's IEM measurement database (5128 target) for IEM profiles and Rtings AutoEQ data for over-ear — they're separate correction chains.
Manual EQ vs. StepFreq: Which Is Worth Your Time?
Building a correct EQ profile manually involves: finding your headphone's measurement data, calculating an inverse correction filter across 6–12 bands, adding preamp normalization, and tuning game-specific boosts on top. It works — if you do it correctly — but it takes 30–45 minutes per headphone/game combination and requires understanding parametric filter math (center frequency, gain, Q bandwidth).
