I love in a house hold with 3 dogs and one cat. I have been constantly woken up by our dogs barking whenever someone returns home late or by our lovely cat who loves to sing the song of her people at all hours, with this it muffles there commotion and allows me to get 8 hours of sleep daily instead of 2 or 1 I have been getting for 4 years.
I will note for those wondering like I was, they do not completely block out sound which is nice for those concerned they won't be able to hear the smoke detector or any kind of super loud commotion, as well as there alarm for work.
