FWIW, I had the QC15 and UFlyMike combo, and I loved them. However, one day one of the ear pieces stopped working. They were only about a year and a half old. My biggest complaint with them was that they never seemed very durable from the start and headsets are used very harshly. I have decided that I will not get another pair. I think I am going to get the Clarity Aloft or Quiet Technologies Halo.
