These are amazing little gems. When we saw them we knew they were something special. A great design and an unbelievable sound, these small cute things pack a huge punch!! With a big sound and a rugged compact case, the Chill Pill is an essential piece of digital traveling kit. The Chill Pill looks and sounds great attached to a laptop, PSP, I Pod, I Phone or desktop computer. They take either usb in or line in via mini jack and usb cables all integrated into the body and spring loaded. We cannot recommend these enough!!!
