Query: Good @ noise canceling, but the folding thing isn't.

The good:The noise canceling tech. is really good. Well, the best one I have. Sometimes, I use them without music to block out street and co-worker's noise.The bad:The folding thing isn't as good as it looks. It's fairly difficult to fold it properly, and doesn't save much spaces.The activate switch is too big and long. It make it harder to be portable and user friendly.
