Decent Noise Reduction
Overall pretty good noise reduction -  100X better than the cheap foam ear plugs.  I bought the small size based on the fact that I have a hard time finding earbuds that fit properly and they are usually falling out.  The small size is perfect.  Blocks out most snoring and heavy disturbances but you can still hear your alarm go off.  With that being said I am a side sleeper and I do not find these the most comfortable.  About midway through the night/ early morning hours I find myself reaching to take them out as they cause my ears to ache a bit.  The material is jelly like and soft yes, but there's just something about them after being in your ears all night that causes a bit of an ache and I'm sure the side sleeping doesn't help that.
