That's how I put mine on. I don't care about the position of the nozzles before I put them on, then adjust the nozzles after by their body pushing them downwards, then slightly upwards until they're on the center for optimum seal. So technically I am using my ears to hold on to the nozzles while using the body/housing to adjust the nozzles, lol. Dunno if it makes sense but that's how I achieve perfect fit. Sorry if my english is kinda confusing, not my native toungue.
Perfect description of what I meant. :)
