hi rob, my advise are the sennheirser's no doubt,
but I stopped using them because I found they just packed wax up my ears...which spoiled the Hi-Fi enjoyment...
.... I know some say not to use a cotton-bud as it can push the wax up even more but I find no problems.
your not suposed to put anything smaller in your ear than your elbow ...
earbuds are dangerous on a number of levels ...
the most simple is just pushing goop further into your ear ..especially if you can't see what yoir doing ..
if you have an excess of wax ..the problem lies elsewhere and need proffesional assistance
