It’s extremely light. Blocks out all the construction noises out of my condo. What’s most importantly, it doesn’t hurt at all.

Most headphones that I have used made me feel quite uncomfortable and irritating after wearing them for too long.

And I was hesitating between this one(Bose qc45) and Sony xm5. At last I chose the comfort over the sound quality I guess. But one flaw is that the labiodental is too obvious.
