You can’t appreciate the difference it makes to have all the peaks and troughs ironed out specifically for your headphones until you hear it. I’m using it with Bose QC20’s and it’s a complete transformation. My only complaint is not Sonarworks fault but Apple’s. The app will not play DRM protected music downloaded from iTunes even though I’m using this app on the iPhone that it was downloaded to. An absurd restriction but great app.

Love it!

I have been using their Studio Reference v3-4 software for a nearly a couple of years now. That’s also how long I have been waiting for this to come to iOS.
Great to see profiles for in-ear headphones such as the Apple and Shure SE options.
I don't use Spotify but I am able to listen to music from iTunes.
One small improvement would be a song search function.

Damn good app

This is very buggy but it really transforms the music.
I can’t stop going through my library listening to tracks that sound so much crisper.
They don’t even list my earbuds but after trying a few settings I get a great result.
Iron out the bugs and this is 5 stars.
