I am thinking of buying a back up, these are really great, I love how it really blacks out all light and it helps because where I live we get a lot of sunlight during the summer aka Land of the Midnight Sun, and I work nights so when I get home and get ready for bed these come in so perfectly and I listen to music to help me sleep as well, and the sound is just right for me, it helps that you can remove and wash. I can say Id recommend this to anyone looking for something that blocks out light while sleeping and gives good quality sound for music and also for calls too. I will admit it was a bit $$ but it was definitely worth it once I used it, the straps hold nicely while sleeping and I rotate in bed like a rotisserie chicken so it holds , especially if you are a hard side sleeper, it is very light and not noticeable while sleeping, and it is really comfortable while sleeping. id give a 5/5
