From my extensive experience and research on the sensitive subject of earplugs I have determined the following.......
This thread is way toooooo long for a simple question on an earplug.
Surely you must all have better things to do than give advice on someones ear health.
And finally.......
Here it comes......
insert left index finger into left ear
insert right index finger into right ear
and use your pinkies to pick your nose if it needs picking.
That way you are guaranteed to never loose your plugs in the future.
