As an ideal companion speaker for MP3 players, mobile phones, iPod series and iPhones, PS10 can be rated as the A++ choice. It can be connected to almost all audio devices with 3.5mm or 2.5mm output jack. It is a mini cube speaker which can stand in three different directions. As it requires no extra audio cable and power cable (it is powered on batteries) in order to work properly, you may operate it as easy as rolling a log. Its extremely miniature size occupies virtually little room of your traveling backpack. It is just like a magic music box staying with you all the time.
