I preface this with the fact that I was given this product to provide a product review. I'm sure if you have read my reviews you have noted that I don't hesitate to do a one star review when a product deserves it regardless of whether I paid full price or not. Conversely if a product deserves a 5-star review, I must give it the appropriate score regardless of whether I received it for free or not. Admittedly I was a bit skeptical when I saw how tiny this speaker was even before I compressed it to it's even smaller travel size. It puts out some darn good sound for something that is smaller than a racket ball. (or for you foodies, a clementine.) I tested it on an Android tablet, a Kindle Fire and a Galaxy S4 phone. It performed superbly on each. In fact I didn't realize how bad the sound output was before it was enhanced. I know on all three devices that headphones are really the only realistic method of playing them unless you are hooked
