I bought these because I can't get to sleep at night without some noise to distract my busy brain. They are pretty comfortable for sleeping on your side. The band is a little tight, but that keeps them from slipping off at night. The only thing I don't like is the charging port. It's the old angled kind and doesn't work with newer cables. And how it's placed is hard to see. The battery life is dang good and lasts me two nights.First day use. Came precharged. First time using eye cover and ngl the center over my blibd folded face as I tey to sleep makes me feel like some freaky mind control device xD. Anyway sound quality is good. Had it on halfway and could not really hear it unless it was over my ears, so that's good. Reallt glad there's no annoying blue led indicator light that shows its on. I like the dark, but as an eye cover with that center buttons, I don't feel comfortable with it right between my eyes.I love this! The noise cancelling is not as good as normal headphones but the comfort and quality more than make up for that. I bought these specifically for sleeping. They are VERY comfortable. The sound quality is great. Battery like is better than my old normal headphones. It lasted me 4 nights. I will be buying more!!I've had at least a dozen sleep masks. This one is easily the best l I have ever had. It's super comfortable. Not hot and completely covers your eyes. No gaps. Battery life is better than listed. And a bonus is that it doesn't have the little dangle cord that most do for charging. The only thing I hate is the mic. I don't need a mic in a sleep mask. Please take it out and I'd give it five stars.Pretty cool combo eyeshade and blue tooth speaker headband. I listen to podcasts as I’m falling asleep. It’s comfortable and the speakers are good quality. It fit loosely, so I sewed a fold in it and now it’s snug. Good buy.Very comfortable and easy to use.I love how soft and comfortable this sleep mask is to wear. It’s good quality, is holding up just fine to nightly use since I got it a couple of months ago. The sound quality is perfect for what it is, it connects easily to my phone for audio, and I can’t feel the speakers AT ALL while I’m sleeping. I’m a side sleeper so that is extremely important. My only gripe, which is really just a bit pick, is that the charge port is mini usb or whatever it’s called, instead of type c. I wish all chargeable electronics would use a standard charger. Anyway, the battery holds out all night, it blocks out ALL the light so my husband can have the lights/tv on and not keep me awake. It does great playing white noise so I can hear snoring or other sounds that keep me up. Definitely recommend this product.I love these! I can not sleep without them.
