This enclosure is very convenient and provides a satisfying sound. First of all it works in bluetooth and thus allows to pair all Bluetooth devices you want (PC, smartphone, ipod ...). You can then play your favorite music with more powerful sound. No cables are necessary, which is very convenient. Additionally the enclosure is equipped with a handle which allows easy transport and hang everywhere. The speaker is normally waterproof (I do not have tried) and lets you listen to your favorite music even in the shower or near a safe swimming pool. The range between the enclosure and the Bluetooth device to which it is paired is 10 to 15m. The enclosure features about 2 hours to see a little more autonomy. Finally they sound pretty satisfactory.
