So far i would say that is it is warm and smooth with some real power to the bass and a slightly subdued treble. It sounds really high quality for sure and moves details up very well from the iPhone 4 or Classic. However is noisy.
Yes that was the reason for a lot of delays and my model certainly still is effected by it. It is not the worst i have heard but present. Another huge niggle is the lack of a true line out :L and YES! :D
