Sometimes when you have new electronics you have a problem pairing them, this paired right away with no issues. I have a hard time falling asleep and these helped me relax. I allowed my daughter to use the mask and now she wants to keep it. I plan on going away on an overnigth and these will be perfect for sleeping in a hotel. I plan on getting my sister in a law a set for christmas becuase she loves to relax in the tub. The speakers a decent for what they are being used for. They are not loud, but for a mask you wouldnt want them to be loud at all. A lot of times when you are wearing a mask the light is about to get under them somehow, I did not have that problem with this mask at all. The velcro in the back is perfect so that mutiple users can use them. I look forward to many nights of good sleep with these, if I can get them back from my daughter :)
