I bought Daydream earplugs regularly because I tried and tested many, but found these to be the most comfortable and effective for sleeping in. Unfortunately in the past few months, the manufacturer has increased the size of the plug and the plastic stalk attached. I've no idea what possessed them and I did complain to Amazon about it, because it has rendered the earplugs too big. Plus it is now impossible to lie on your side when wearing them as the stalk digs into your ear.
If you bought this item in the past, please be aware that the difference in size is noticeable. I won't be buying these again.
