As of writing, they fixed bass leaks, almost fixed 17k hz leak and I’m not sure, but they are trying to equalize default speakers?

Where did you hear about any of this??

I trained my ears 1 year using the EQE app and experimenting a lot of frequency reductions.

Actually they fixed iOS related bass leaks that were there even on iOS 6 (my iPhone 3GS). Headphones that have bass amplified won’t simply get reduced, just iOS got fixed. Also, with default speakers I actually wanted to say built-in.
