Mack's Ultra Soft Foam is the plug to try first if the problem is a loud snorer and the budget is small. Mack's gives it a Noise Reduction Rating of 33 decibels, its highest, and that is the top rating on this list. The foam is what Mack's calls Comfy Cush comfort foam, made to press gently on the ear canal as it expands, which is the main thing that separates a sleep-friendly foam plug from a stiff industrial one. Packs on Mack's own store start at $2.99 and go up to bulk counts with travel cases, so you can try a pair for the price of a coffee. The tradeoffs are the usual ones for foam. You need to roll the plug thin and let it expand in the ear to get a seal, and a plug that is not deep enough will block far less than its rating. Foam also sits further out than the low-profile silicone plugs here, which some side sleepers feel against the pillow. Mack's makes the plugs in the USA.

Who it is for

Light sleepers next to loud snorers who want the most blocking for the least money.
