You know they always say great things come in small packages. I am shocked to say this is on of those little packages. This little gadget would think you it is bigger by the picture. It is actually smaller than a matchbox, the bigger ones. It comes fully assembled and it has all the cords tucked neatly under it. I am trying to remember what is in the box, I am for sure the product and a charger cord. I think there was something else with it as well but I am not sure. Maybe you can tell in the picture. Besides that the product is very simple. You get it, ensure it charges to full capacity, about an hour and a half or maybe 2. Then you plug it into any aux jack, turn it on. Then you pair it to the code that can even be found on amazon under the product description. From there you can enjoy music wirelessly. You can even take phones call and talk, due to the built in mic. I actually purchased 2 of them, I just think the gadget is so neat. You probably do not notice it but the device is sitting right on top of the box.
