I did a ton of research on this mask. Between Reddit, reading reviews, and watching YouTube videos. I am extremely happy with this mask. I've had it for about a week now. I wanted to wait and use it before writing my review.
As far as an eye mask goes, this mask uses a very soft, cooling material. It is padded around your eyes so you don't feel the mask on your eyelashes at all. It also has extra padding around the nose that blocks out absolutely all the light. The Velcro on the back is very strong and never sticks to my hair.
As far as the Bluetooth goes, I love it. The speakers are able to be moved around so you can place them where you need them. They are thin so I never feel them if I sleep on my side. They are not noise cancelling but they are very crisp and can get loud. I never have to turn the volume up more than halfway when using them. I watch Bob's burgers when going to sleep and the intro can get loud. I like that it's just loud enough to hear while falling asleep but not loud enough to wake me up in the middle of the night when a new episode comes on. The battery life is amazing. I sleep for 9-10 hours a night and I get 3 nights of usage before having to charge the mask. It also only takes about 30ish minutes to charge the mask.
All in all, this is by far the best thing I own. I genuinely look forward to going to bed every night lol I will absolutely be purchasing again when the time comes. Don't pass this mask up if you're considering getting a Bluetooth sleep mask!!
