I wanted the QC15 because I didin't want wireles...s/bluetooth/microphone etc., I just wanted quality noise cancellation and I got it! The headphones operate via a switch on one side, which turns on the noise cancellation. The difference is astonishing! They are so good, I even pull the cable out and use them without sound when I want some peace and quiet. Downside is, they don't work at all when NC is turned off. I don't think there is a better brand on the market.
