Nice warm hat...if you are buying this for great sound...don't. Music sounds like it us being funnel through a cup and string..audio from the phone sounds the same. Great idea but the execution leaves a bit to be desired.

didn't work

Blue tooth beanie only lasts about an hour after a full charge, Hard to turn off and on. not a high rate

I wear this around almost daily and it worked beautifully the first 2 weeks, but now it’s not holding a charge! I thought it was my cord, but no! I used 3 different cords and they all were fine. It’s just my beanie randomly stopped charging! How irritating!
