Follow the in-app instructions for best results
1. It's safest to UNINSTALL all other Equalizer apps
(There might be exceptions but many problems arise from having multiple apps using audio effects)

2. Press ENABLE in SpotEQ31
You will see a small notification indicating the app is working in the background (pressing the notification will open SpotEQ 31 again).

3. RESTART PLAYER APP and play music
Stop and close (swipe away) the app, then reopen and play a new track. Easily hear change with preset Low Cut.

4. CONFIGURE the equalizer
Adjust each ear EQ with Separate channels. Set a Preset or configure individual bands for your needs. It might be helpful to lower the Pre-gain when using the EQ with some Bluetooth headphones. To be able to hear the effect of the highest and lowest frequency bands you will need great headphones and hearing capabilities.

5. IF YOU HAVE PROBLEMS, If an app breaks the audio connection, try to pause/play or start the next track. If not working, try to completely restart SpotEQ31 and/or the player app a few times (close & swipe away). If nothing works try to power off and reboot your device after uninstalling all other audio effect apps. Sometimes the Android audio engine needs a reset

Do not unlock features before you managed to connect your music player.

Fix bad headphones
If you have bad or broken headphones/earphones where the sound is uneven in left and right ear, you should be able to compensate for this by using this app. Some headphones may sound better and avoid distortions if you use the pre-gain to lower the volume while adjusting the equaliser.

Improve your music experience without a hearing aid
If you have a hearing impairment and are using a hearing aid in your daily life, you can try to compensate the sound with this app. Just adjust both left and right side frequency bands, and depending on your specific hearing loss you might find a setting that hits your sweet spot for listening to Spotify without your hearing aid! Consulting your audiologist or audiogram is advisable. Sometimes a simple volume balance to left or right side can do wonders.
