If you’re using Heavys H1H headphones, chances are you love powerful bass, crushing drums, and aggressive guitar riffs. These headphones were literally designed for heavy music fans, and right out of the box, they deliver a massive, skull-rattling low end that feels more like standing in front of a live stage than listening at home.
But here’s the truth most reviews won’t tell you: stock tuning isn’t perfect. In fact, without EQ, the Heavys H1H can sound muddy, closed-in, and overly bass-dominant, especially on PC. That’s where Equalizer APO comes in—and in 2026, it’s still the most powerful way to unlock the true potential of these headphones.
This guide combines real user experience, community-tested presets, and expert tuning logic to help you achieve the best EQ settings for Heavys H1H using Equalizer APO. Whether you’re into deathcore, metalcore, gaming, or even cinematic audio, this article will help you dial in cleaner mids, tighter bass, and clearer highs—without killing the signature heaviness.
Understanding Heavys H1H Headphones
Design Philosophy: Built for Heavy Music
The Heavys H1H headphones were marketed as the world’s first headphones designed specifically for heavy metal—and that’s not just branding hype. From the moment you put them on, you can feel that these headphones are tuned with impact and aggression in mind. The low-end response is intentionally boosted to emphasize kick drums, bass guitars, and downtuned riffs, making genres like deathcore, djent, metalcore, and hardcore feel larger than life.
Physically, the headphones are over-ear, closed-back, and wireless, featuring a solid clamp force that enhances isolation and bass response. The ear cups are tuned to create pressure and resonance, which contributes to that chest-punching sound many metal fans crave. However, this same design choice can also introduce frequency masking, where bass overwhelms mids and highs.
Sound Signature Out of the Box
Out of the box, the Heavys H1H follows a V-shaped sound signature, but with an exaggerated low end. Sub-bass and mid-bass are heavily elevated, while mids—especially upper mids—are slightly recessed. Treble exists, but it’s smoother and less forward to avoid harshness during long listening sessions.
This tuning works well for:
-
Heavy metal
-
Deathcore
-
Industrial rock
-
Live recordings
But it struggles with:
-
Vocal clarity
-
Guitar separation
-
Gaming positional audio
-
Long analytical listening sessions
Without EQ, instruments can blend together, and vocals may feel like they’re sitting behind the mix instead of cutting through it.
Strengths and Limitations Without EQ
Strengths:
-
Massive bass impact
-
Immersive soundstage for closed-back headphones
-
Non-fatiguing treble
-
Excellent for aggressive music
Limitations:
-
Bass bleed into mids
-
Recessed vocals
-
Lack of clarity in complex mixes
-
Not versatile across genres
This is exactly why custom EQ is not optional—it’s essential if you want to get the best out of the Heavys H1H in 2026.
What Is Equalizer APO and Why It Matters in 2026
How Equalizer APO Works at System Level
Equalizer APO is a system-wide parametric equalizer for Windows, meaning it applies EQ adjustments to all audio output, regardless of the app you’re using. Music players, browsers, games, streaming services—everything passes through it.
Unlike basic graphic EQs, Equalizer APO allows:
-
Unlimited EQ bands
-
Precise frequency control
-
Advanced filters (peak, shelf, high-pass, low-pass)
-
Preamp control to avoid clipping
This level of control is crucial for bass-heavy headphones like the Heavys H1H.
Equalizer APO vs Manufacturer Apps
The official Heavys app includes a basic 5-band EQ, which is fine for quick tweaks on mobile. But it lacks precision and doesn’t apply system-wide on Windows.
Equalizer APO wins because:
-
More frequency bands
-
Parametric control
-
No latency
-
Works with Peace EQ GUI
-
Community presets available
In 2026, despite new AI-powered audio tools, Equalizer APO remains the gold standard for manual tuning.
Why Audiophiles Still Prefer It in 2026
Audiophiles value consistency, transparency, and control. Equalizer APO doesn’t color your sound—it simply reshapes it based on your preferences. It’s lightweight, stable, and endlessly customizable, which is why it’s still widely recommended on platforms like Reddit, Head-Fi, and PC gaming communities.
Why Custom EQ Is Essential for Heavys H1H
Fixing Bass Bloat and Mid Masking
The biggest issue with the Heavys H1H is bass bloat. While the sub-bass is fun, the mid-bass region (80–200 Hz) can overpower everything else. This causes mid masking, where guitars and vocals lose definition.
A proper EQ:
-
Reduces muddy frequencies
-
Tightens bass response
-
Restores mid clarity
Improving Instrument Separation
Heavy metal mixes are dense. Double kick drums, layered guitars, synths, and vocals all compete for space. EQ helps separate these elements, allowing each instrument to breathe.
Boosting:
-
2–4 kHz enhances guitar bite
-
3 kHz improves vocal presence
-
6–10 kHz adds air and detail
Expanding Use Beyond Metal Music
With EQ, the Heavys H1H becomes surprisingly versatile. You can enjoy:
-
Gaming with accurate footsteps
-
Movies with cinematic punch
-
Rock, EDM, and even podcasts
Custom EQ turns a niche headphone into a multi-purpose audio tool.

Firmware, Bluetooth Codecs, and Wired Mode
Always keep the Heavys firmware updated. For best EQ accuracy, use wired mode when possible, as Bluetooth compression can slightly alter frequency response.
AutoEQ, Measurement-Based Tuning, and AI Tools
If available, AutoEQ profiles can provide a starting point. Combine them with manual tweaks for best results. AI tools are improving, but human tuning still wins for personal taste.
Listening Tests, Fine-Tuning, and Long-Term Comfort
Test with familiar tracks. Adjust slowly. Your ears adapt over time, so revisit your EQ after a few days. Comfort improves when harsh frequencies are properly controlled.
