The bigger the ear tips are the less distance they go into your ear to be effective. With the gray or pink ones they go so far into my ear they make my ears ache. The black ones are large enough they sit outside of my ear and block the noise much more effectively. I think the problems people have with these headsets is they shove the insert to far into their ear canal.

Manufacturer packaging is poorly sized. The tips were jammed into the packaging so tightly that it was difficult to remove without destroying the tips.
