I have the QC25s, they're great. Sound reduction is great when you need it, not too hot, good weight, great sound quality, decent when used as a mike. Plus fold up a bit so you can fit them in laptop bags in a pinch. If you want the noise reduction on all the time though, you'll be switching batteries every few days (easy to do). Wonderful on plane journeys. Well worth the money. Wired is slightly annoying, but my previous Corsair wireless headphones were too heavy and always seemed to need plugging in at the most inopportune moments.
