I really love this sleep mask. I have been wearing eye masks and earplugs with an air purifier and sometimes noisy fan to drown out any noises by my husband or dog since I am a very light sleeper. I recently bought another sleep mask which is fine to use when he is not around, but then I saw that there were other masks with sound built-in so I looked around and this mask had good reviews and had the 3D eye holes which I wanted. I have been using this mask pretty much daily and am very happy with this product. The mask is comfortable and blocks the light for me.
I use an iPhone and a White noise app listening to a "Stream water flowing" when I sleep. I do notice that you need to have the Bluetooth device close by. One night my husband moved my phone to the other side of our king-sized bed so I could sleep in and not hear the alarm as he was going to wake up with the kids instead and the sound kept getting interrupted and "sputter" with silence in between like a bad connection which ended up waking me up. So now I use an old phone strictly meant to provide the white noise sound. I tried a really old ipod touch but it only provided sound in one year so that didn't work especialy because it was the left ear that didn't sound and that is the side my husband sleeps! Also, be careful when charging that you don't pull the wire out too much as the audio unit inside gets misplaced and you have to maneuver it back to the right position.
I was able to move the earphone parts so it covers my ears fine. I do still wear earplugs as well as I am used to it and it helps keep extra noise out.
I had some questions after purchasing and they got back to me very quickly which was nice.
I keep the mask charged when I am not using it and it lasts me a very long time as I like to sleep! After the kids go to school sometimes I go back to sleep and the mask still lasts as long as I nap even with the small charge in between.
Again very happy with this sleepmask.
