What this app is

Wavelet — Headphone Specific EQ is a free Android equalizer made by independent developer Pittvandewitt. It gives you per-headphone tuning via a nine-band graphic equalizer and tools to manage channel balance and limit volume peaks. The interface works with both wired and Bluetooth headphones and is designed to make real-time adjustments straightforward.

How it tunes headphones

The app draws from the AutoEQ Project and uses the Harman target curve as its reference for “neutral” sound. Rather than generic presets, Wavelet provides model-specific corrections that aim to bring many headphones closer to that reference. The built-in database contains more than 5,000 ready-made profiles for popular headphone models that you can apply instantly.

Built-in controls and utilities

  • Nine-band graphic equalizer for manual shaping of frequency response
  • Limiter to prevent clipping and reduce sudden volume spikes
  • Channel Balance control to correct left/right level discrepancies

These tools let you either rely on an AutoEQ preset or tweak the response yourself if you prefer hands-on adjustments.

Upgrades available

Wavelet offers an optional Pro upgrade that unlocks additional processing:

  • A volume normalizer to keep perceived loudness consistent across tracks
  • An enhanced bass tuner for finer low-frequency shaping
  • Spatial and reverb modules to add width or ambience

The extra functions are aimed at listeners who want more advanced sound customization.

Known reliability quirk

Some users report the app sometimes stops functioning when running in the background. If you encounter this, try exempting Wavelet from battery or memory optimizations in your device settings and keep the app open while streaming, as those steps often reduce background termination.

Who will benefit

If you care about precise headphone response—whether you want to hear a flatter, reference-based sound or simply improve a set that sounds off—Wavelet is a solid, user-friendly option. The AutoEQ presets are a quick way to approximate the Harman curve, while the manual controls and Pro features suit listeners who want deeper customization.
