Downsides outweigh the incredible comfort
I live in a country-based suburb of a large city.  The main road near my home is a drag strip so I have to wear ear plugs to sleep comfortably.  Having inserted ear plugs more than a few hours becomes uncomfortable.  The reviews on these stated the most comfort, and, without question, that is very true.<br /><br />The problem with these are two-fold.  One, you must ensure your hands and ears are COMPLETELY oil-free.  If not, they will almost immediately lose their seal.  Instead of using my go-to Dove unscented, I have to wash my ears with Dr. Bronner's pure castile soap to remove every trace of body oil.<br /><br />The second issue is that, as soon as you have them fitted as recommeneded, they begin reshaping to their original form of a cylinder.  What I've found is that they can more easily become dislodged if you're like me, a side sleeper, and have your hands under or near your face and ears.<br /><br />While these are beyond comfortable, I feel their downside outweighs that upside.  They are a waste of money.  I strongly recommend Mack's Pillow Soft silicone ear plugs.  They are far superior, and what I have replaced Better Sleep ear plugs with.
