Absolutely the best selling gift in our store! These super loud little speakers come with a usb cable for charging in your computer and a cable to plug into any mp3, ipod, iphone, mp3 player, computer, you name it as long as it has a headphone jack. Charge for 2 hours for approximately 5-6 hours of great sound. Perfect for hiking, the beach, the firepit, the cottage; anywhere you would like to get the party started but don't have a plugin for a docking station. We've had fans buy 5-10 of these at a time for gifts and it's must have here for all of us! Comes in 3 colours and is about the size of a golf ball (plus the headphone cable).
