Open Easy Equalizer
Open the extension from the browser toolbar. Browser audio and Quick EQ are ready on the first screen.
Activate Pro
Turn your license key into Pro access.
If you just paid, Pro is already unlocked in the browser used for checkout. Use this guide when setting up another browser, reinstalling, or recovering your key.
Every image highlights the exact control to use and contains only a safe example key. Your real key is unique to your purchase — never share it or paste it on another website.
Automatic Pro unlock
Pro unlocks automatically after checkout.
Your license key is also emailed as a backup for another browser, recovery, or device management. Click any screenshot to inspect the highlighted action.

Open the Pro tab
Select Pro in the side navigation. It stays available even while Browser audio is off, and your Free, Trial, or Pro plan is always visible in the header.

Use the license tools
The always-visible license form includes both activation and email recovery in one place.
4
Paste the key and activate
Paste the key from your purchase email, then choose Activate Pro. A key supports up to three devices.

Confirm Pro is active
After activation, the header changes to PRO and every paid control unlocks. Use Manage license if you need to move devices.
