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 lower the pre-gain.

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 music without your hearing aid! Consulting your audiologist or audiogram is advisable. Sometimes a simple volume balance to left or right side can do wonders.

Thank you for trying out SpotEQ31! If you have any suggestions please contact by mail.
