the noise canceling is very good and the EQ settings via iphone app really opens them up and let you cover a wide spectrum... I tested on a few non-mastered tracks and A-B them and I am happy with the overall recreation of the sound... anything below 70Hz is not reproduced- however with the noise canceling you do feel the pressure if you play a clean sine wave...
BTW: I did these tests wired, not using the bluetooth capabilities... I would not recommend using bluetooth for production- I would only use BT for album listening and track playback outside of the studio
