While there are more than a couple of which headset threads floating around, I thought that this had better be placed into a seperate thread, as to not be brand specific.
looking on data for a headset that I am looking at buying, I found the two articles on the following link to be most useful. Yes it is from a company selling headsets, but the information in them appears to be useful in understanding and comparing headsets across all manufactures.

so, has anyone else got any other useful links to share with us
( ps, i wasn't so certain where this should go to be the most useful, as it seems to apply equally to most of the forums )
