Audio quality is very good. My only complaint is the app doesnt allow for deeper integration in iOS for "send to app" functionality. This limits its usefulness to me and locks me out on the fly from testing songs not on iTunes... The iTunes share idea is a pain in the $&)(... In an age of the cloud. So add some inter-app operability and Ill tell everyone to buy this.
