DO NOT restrict yourself to trying DCs. Like quite a few others here I do not like them at all. I find them to be heavy, cumbersome, constantly slipping off my head and with poor external noise insulation. I am fortunate enough to have a Peltor headset on permanent loan with which I am very happy but should I eventually buy my own set I shall be looking at anything EXCEPT DCs. Go and look at several different makes and TRY them, don't just buy a set because "Everyone has them." There have been several threads recently on the subject of headsets, I would suggest you have a look through them at the various thoughts and comments.
