🔬 Automatic earphone correction (AutoEQ)

• 8,750+ AutoEQ profiles built from real measurements
• Connect a Bluetooth device and it finds the match and applies it
• Or search by name and pick one yourself
• Applied to the sound the moment you choose

Earphones and headphones all sound different. Some are short on bass, some
have sharp treble. Measured data fills in that gap and brings the sound
closer to what it was meant to be.

If your device is on the list, choosing it is all you have to do.

⸻

🎚 The sound you want, in one tap

• Balanced sound · Fuller bass · Clear voices · Sharp detail · Powerful sound
• Choose which items sit on your home screen (3–8 slots)
• Set how far it goes with the intensity slider

You don't have to work out what to touch, or how much. Tap the direction you
want and the matching settings are applied together.

⸻

🎛 If you want to go further

• Bass · Treble
• Vocal · Loudness
• A graph shows how the sound changes while you adjust
• Space — Natural / Wide Stage / Vocal Room / Cinema

Four sliders are enough. The centre is the sound you have now, and moving
left or right changes only that much.

⸻

🔊 When the volume isn't enough

• The Loudness slider corrects the overall level
• A limiter works alongside it so the sound doesn't break up

Quietly recorded music is lifted, and loud peaks are held down. Use it as a
sound booster, but only up to the point where the original sound stays intact.

⸻

🎵 36 sound presets

• Basic — Flat, Bass Booster, Treble Booster, Vocal Booster and more
• Genre — Pop, Rock, Hip Hop, EDM, Jazz, Classical, R&B, K-Pop, Metal and more
• Mood — Lounge, Late Night, Live, Party, Podcast, Audiobook, Cinema
• Instrument — Acoustic, Piano, Drums, Bass Guitar, Violin

You can see the curve and a one-line description before you choose. Apply it
only if you like it.

**All 36 are available with no limits.**

⸻

💾 It remembers what you set

• Every preset keeps its own adjustments — come back and they're still there
• Per-earphone settings saved and restored automatically
• Save a sound you like under a name

Turn the bass up on Jazz, move to Rock, then come back, and the Jazz sound is
exactly as you left it. Plug in different earphones and the settings you used
with them come along.

⸻

🔄 Checking whether it really changed

Press and hold the button at the bottom and the correction stays off while you
hold. Let go and it comes back on. You can switch between the corrected sound
and the original right away.
