I bought this for my 12 year old daughter for Christmas. It came quickly with a small two-page instruction manual. A USB charging cable was also included. It took about 2 hours to charge my computer. I actually had to take the Bluetooth part out of my hat for 5 minutes to study and understand how it works. (No support site.) I was then able to sync it to her phone with no problem and she can listen to music up to 20ft from her phone. The sound quality is actually very good. I haven't seen her answer the phone with it, but she texts her friends all the time instead of speaking, so it probably won't be used anyway. The hat itself is warm but she complains that it's cramped. She is 5ft 8in at 165# and very athletic. She's not used to tight things, maybe that's why. I don't think it is at all, but I'm 4 inches shorter and 40# lighter. I personally think it's very cool and would love to have one to run.
