C&B and The Odd One, I agree. They are light (compared with DCs), comfortable and fold into a small space. I have had to use DCs on the odd occasion and find them very uncomfortable, heavy and unwieldy and they don't deaden as much external noise as the Peltor ones. They also tend to keep slipping off my head which can be dangerous if it happens at the wrong time. When I can afford to buy myself some (these are on long term loan from a friend) I shall be buying Peltor.
