Comfort - Several have noted that the cups for the PXC 550 are smaller than the QC 35. Merciii Amazon cest super jolie je ladore merciii, confortable parfait pour aller travailler, à léglise cest parfait 5 étoiles youpi ???????? I tried a few other brands - Mizuno, Babolat, Wilson. Its loose and comfortable its not exactly see through but it is slightly sheer. I have never found sandals like this that fit me before! With Origami, its worth checking out their website cuz they run their own sales & you may get a better color selection. It served its purpose though and I am pleased with my purchase. When I have them on I can?t hear any other noise. So far so good, I love it! A relatively inexpensive pair of Bose headphones, these sounded great out of the box, an obvious improvement over anything Ive owned before.
