I try to hear depth, in the sense of what feels closer. Maybe it helps? ;)

Yes that's what I was thinking too. I'll try to focus more on that, thanks :)

Listen to the first loop a few times, and give your brain a chance to adjust and get a feel of what you’re hearing.
Then switch back and forth between 1 and 2. If you don’t notice a difference go back to 1 and readjust to it. Then switch 1 to 3. Any difference? If not switch back ad forth between two at a time. If you switch back and forth without it jacking with your ears they are most likely the same. Then you can double check by going to the one you think sounds different, and flip it back n forth to listen for differences.
But, it’s not easy. Some will be more obvious than others. And it Only gets more difficult. But it doesn’t seem “as hard” once you kind of develop your own way of approaching it. Keep at it I know how frustrating some of these games are. But, even the hardest games you Will get better at. Trust yourself, and cut yourself some slack. It’s not just easy. Not for me anyway Lol. Hope out of all this Some part of it was helpful. 🤘

Thanks for the advice! I'll give this method a try, sounds promising!
