Query: A bit flimsy..

I've owned these headsets for just over a month now. The padding on the ear cuffs keeps coming off and it is impossible to put it back on properly. I mostly just rely on the headset pressure (which is not bad) to hold them in place while wearing. The active noise cancellation does indeed work, but it really is no big deal (on this headset or any other). I never really even bother to turn it on anymore. Then general sound quality seems fair enough.
