The following earplugs I would recommend all because they all have really no noticeable difference in sound insulation with no restrictions on the work or other activities outside of sleeping. Here are all good.
Place 1. 5 points: Bilsom 303 small. Bilsom are the plugs for sleeping you to other brands are much softer than the small are ideal when a lot on the side sleeping as they are slightly shorter than everyone else but just insulate well.
2nd place 4 points: Bilsom Laser Lite. Suitable for sleeping well and still more comfortable than ear plugs and Elastoplast although they are longer than any other.
3rd place 3 points: earplugs and Elastoplast. Are good plugs for everything except sleep as hard material.
