Best sleep and study sessions with these
I love that these came with a few different pairs to try out and that each pair has its own carrying case. The blue earplugs are my favorite. They're super comfy and I get my most restful sleep whenever I have them in.  It doesn't 100% cancel sound but it does a really good job at muffling background noise and conversations. The noise level with the blue ones in is comparable to what noise would sound like if you were underwater.  The orange earplugs feel a lot more stiff in your ears but cancel more noise and are good for short term wear. The gray ones are too big for my ears and I haven't played around with the clear ones yet.  Overall, I'm really happy these and love to wear them when sleeping and studying.
