I uninstalled Boom 2 from my Mac. I found after several adjustments that I preferred my Focal Elears as they are. The necessary boost in the higher frequencies ended up being tiring, so I reduced it, basically getting back to the sound signature that I have. Alas, nothing gained.
Downloaded Sonarworks' program, and it appears from a quick try to be much better. These are my observations (having my Elears directly attached to my iMac):
( ) Without the True-Fi enabled the Elears appear muffled.
( ) The soundstage is wider and the sound is more forward leaning.
( ) The balance is better.
( ) The "Adjustment for Age" works well giving a good boost in the higher frequencies.
( ) The user interface is easier to work with than Boom.
I would suggest that you try it out - there is a 10-day free trial period.
