Should I use the equalizer?

Hello there, I'm curious about your thoughts on using the equalizer in audio settings. I've heard it can enhance the listening experience, but I'm not sure if it's necessary or even advisable to use it. Could you explain what the equalizer does, and give me some guidance on when and how to use it effectively? I'd appreciate any insights you have on balancing audio quality and personal preference when it comes to adjusting the equalizer.
