I'd like to buy a nice pair of headphones but that's the thing that worries me. I'm not at all bothered by the background noise (e.g. aircraft engines) but human-made noises are very distracting. There seems to be nothing that can filter them out; my current passive headphones will muffle conversation a bit when I've got white noise playing through them but throat-clearing cuts right through.
