Review on Stay Warm And Jam Out With Rotibox Bluetooth Beanie Hat: Perfect For Outdoor Sports And Xmas Gifts by Megan Smith

Very nice design, disappointed I didn't notice all the other cool hat designs before I ordered. Giving it 4 stars instead of 5 because there was nothing in my package to provide any instructions on how to sync with Bluetooth. Came inside a printed bag, at least they could have done was include a web address on the bag, or on a business card inside. Had to google to figure out how to sync - press and hold Play/Pause until flashes between red / blue. Also, no charging cable, if you're like most android phone users you probably have a handful of USB Micro cables around that will work for this.
