2 plus years later I still have my iA7.  One big gripe I have with it, is that when its either hanging from my neck, on necked and in my t-shirt pocket .. the Slide Control gets stuck going Back.  When this happens none of the other buttons work and I have to power it off. Mind you I have it on Lock/Hold, and you can set the side + and - buttons for Volume, track forward/back, and the M (menu) button to pause/play.  When its stuck like this and I take off the Lock, it skips back track after track after track.
 
Lately I've been listening to my HA-FX34s (Marshmallows 2.0), and only have the 3D Surround set to 3, everything else is off or flat.
