I'm giving 5 stars because I was trying to fix my air pods which were inverted. Using the app somehow fixed it, even though I never really got a setting for it. I guess it was from running the earphones test in the first place. Talk about a bonus score. Anyways, the 3d natural sound and different sound tests were actually good. The door knocking thing got me. Overall excellent app. Thanks

I need a simple left/right balance control. This app is a nuisance to operate due to ads and it will not control balance. The testing is interesting, if the pop-ups don't drive you away.

Too many ads. There are ads after every single button I touch, and while I get they have to pay thenselves somehow, it's too annoying. The app was also not what I was looking for, but that's obviously not the developers' fault, but definitely mine.
