So I won a pair of Bose QC15s yesterday, and I was set to "regift" them to someone. Of course, I couldn't resist coming here to read reviews first. Now I'm torn.... I don't want to open these and hate them, because then I'd feel tacky giving them away as a gift. But on the other hand, I could just give them to my husband and finally have those Metallica edition SkullCandy cans "accidentally" disappear. I also have a pair of Bose AE2 (also won those), and I know how comfortable they are. However, they sound like a tin can and I only wear them on cold days when walking the dog because they fit nicely over a hat..... If these are like that, well, I don't need anymore crappy cans/ear muffs for the winter. So to help me decide, can anyone tell me what a noise cancelling experience is like vs. an open backed headphone and why I would want it? I listen to 95% of my music via HD598s and am now used to the soundstage of that can. I really don't think I'd enjoy a noise cancelling head phone while sitting in my armchair, reading a book. I like using IEMs on flights, so I doubt I'd use them on a plane. Anyone else who has these, what do you think? Obviously price isn't a factor here for me since they were free, but if they are garbage at any price, I'd rather gift them to someone who doesn't know better.
