I bought mine after demoing at Best Buy. I was comparing them to the Sennheiser Momentum (forget which number) and one other headphone that I forget. The QC35 were the last ones I put on. They were immediately head and shoulders above the others just in terms of comfort. They were so light they virtually disappeared on my head and ears. Amazingly, the sound quality was almost irrelevant, although they were my favorite in that regard as well. (I've heard the Sonys might have slightly better ANC, but most of the competitive models are fairly similar which each having one area they're slightly better than the others). The only thing I felt I was giving up in the Bose is in power. When I demo'd them, I ran them up as loud as I wanted to go. Then I tried to go one notch higher, and found I was already at the top. Over the years, I've found the exact same thing. They go exactly as loud as I want and no louder. Every once in awhile, I try to push it a bit more, and find I'm already at the top. Impressively, they never clip, and the bass is always "just enough". But I'm sure for some folks that won't be quite enough.
