Every pair of headphones — even expensive ones — has its own built-in "colour": maybe too much bass, or sharp, harsh highs. TuneHub fixes that automatically. It loads a ready-made correction made for your exact headphones, earbuds, Bluetooth speaker, or even your phone's built-in speaker, so they sound the way the music was meant to sound. It's free, and for most people it's the single biggest improvement in the app.
How it works
No headphone is perfectly neutral. Each model adds its own emphasis — one might exaggerate the bass, another might make voices sound distant or cymbals sound piercing. Audio labs measure exactly how each model bends the sound.
TuneHub takes that measurement and applies the opposite: where your headphones add too much, it gently takes some away; where they're weak, it adds a little back. The result is a more even, natural balance — closer to what the artist and engineer actually heard in the studio. It does this very precisely, across 127 fine slices of the sound.
The corrections come from three places, and each result is labelled so you know where it's from: AutoEq (a big community project that measures headphones), Community presets (tunings people have shared), and our own measured speaker corrections (for Bluetooth and phone speakers). A label of "auto" means TuneHub recognised your connected device and matched it for you.
What you can use it for on your phone
- Make inexpensive earbuds sound noticeably more balanced and pleasant.
- Fix a specific complaint — "too boomy", "too sharp", "voices sound far away" — without learning any EQ.
- Get a real improvement on a Bluetooth speaker or your phone's thin built-in speaker.
- Keep a separate correction for each device (commute earbuds, home headphones, the car) that switches automatically when you connect it.
How to use it
Open the TuneHub picker from the device card at the top of the screen, then:
- Tap the preset chip and type your device's name (for example, "Galaxy Buds2" or "Sony WH-1000XM5").
- Or just connect your Bluetooth headphones — TuneHub often recognises them and matches automatically (you'll see an "auto" label).
- Pick the result that matches your model. The change applies instantly, and AudioMatch remembers it for that device.
- If your exact model isn't listed, choose the closest one from the same brand or family — it will still be close.
Why it helps
It removes flaws that are baked into your headphones, so bass tightens up, muddy voices clear, and harsh treble calms down — without you needing to understand any of the controls.
Because it's the foundation, everything else you do (your own EQ tweaks, the personalization wizard) builds on top of an already-accurate starting point.
Settings explained
- Preset — The correction that's currently loaded, labelled with where it came from (Community / AutoEq / measurement). "auto" means TuneHub matched it from your connected device. Tap it to search for a different one.
- Loudness compensation — A safety switch you should leave ON. Corrections often involve turning some things down, which can make everything a touch quieter overall; this quietly makes up the difference so the volume stays the same before and after.
What the live display shows
The green line is a picture of the correction. The left side is bass (low sounds), the middle is the mid-range (voices), the right is treble (high sounds). Where the line rises, TuneHub is adding a little; where it dips, it's taking some away. If you switch Loudness compensation off, the whole line drops below the centre — showing how much overall volume the correction would otherwise remove.
