Sleeping with a very loud snorer, ear plugs and pillows over the head just do not work. Having had these only for a week, they are truly a game changer. Using the Hibernate along with the earplugs, I sleep so much better and longer. As a side sleeper, I was a bit skeptical, but was more than pleasantly surprised as they are comfortable and do not feel bulky or hard. If you are expecting them to feel like the large headphones (as I was), they don’t! Definitely worth the cost!
