Morttic Bluetooth Beanie Hat with Light, Unisex LED Cap with Headphones Built-in Stereo Speakers & Mic, Christmas Gift for Men Women Dad (Black)

This hat is awesome! I haven't used the mic, because I don't really talk on the phone much, but I have done some projects that have ran into the night. I'd say I have used it for 15 hours on the original charge. Listening to my Pandora on my phone and using the headlight. I think it's awesome and will use it a lot! If I had any cons, I would say it's the thin wire in the brim. You need to make sure it's tucked in. I almost got it snagged ducking under something, but pushed it down and haven't had a problem.
