I just received my muse mini in the mail yesterday. They really mean mini portable speaker. I did not anticipate the unit would be quite this tiny (slightly taller and about as wide as a golf ball), but considering the sound this little guy blasts out I couldn't be more pleased. The volume compares to the speaker on my iPad 3, but the sound is richer and less tinny really making a difference. I plan to take this speaker with me when I travel and connect it to my phone. Besides being easy to pack, I look forward to using bluetooth to avoid having cords all over the place. That said, a cord is provided if you would rather not kill your phone battery. The speaker connected to iPad via bluetooth almost immediately, and the battery charger has a USB connection like most of my other electronics making it easy for me to travel with one charger.
