OK, thanks Spuds for the reminder I should update this thread. LOL
Quite simply, I've been using those Mitone cheapies for a while now and have they have had loads of use. They really aren't bad for the price, but they do get a little uncomfortable after a while, but that is because of their shape pressing against my outer ear (they are more long and cylindrical). The bose ones shown below are probably more comfortable.
So in summary, for now I am happy. I would like to test out a proper set of normal shape phones to test "the big phone up sound cancelling" cans vs the "in your ear block out all sound" cans and then make a call from there. I'm back in SA again in week 33 so will prob test out some in a sotre somewhere and check how "cancelling" the sound cancelling ones actually are.
