Revised review

When I select my iTunes library as the music source, it shows the names of playlists, artists, albums, and songs but they appear as empty files. ........

Revised review. It must take time for the app to collect the information it needs from the iTunes library. After going away for 15 minutes retrying , it found my music and working as advertised. I’m using Bose QC 35 with noise reduction enabled. The sound is better with a nice boost in my age related frequencies.

Awesome app 554472 ,

Not quite there, but hopefully in a future update.

I rate the app 4 stars because I know how amazing Sonarworks is, but the app has a major flaw, which is importing music. I was impressed to see that it bypassed DRM protection and actually let you see your Apple Music library, but I can’t play any songs! The songs just don’t show up. I cannot rate the rest of the app unfortunately because I haven’t been able to use it.

Read an article about this app and was really interested if it could live up to its claims. I was incredibly, pleasantly surprised. I pulled up a song that I know very well and used my Bose QC35II. I compared within the app and then listened in iTunes and the difference was dramatic. Very cool use of tech to unlock the power of different headphone types!
