The A100 are great budget friendly speakers that get the job done. As of the day this video was filmed these speakers will only run you about $13.99 at amazon.
These speakers are not going to set any house of fire but they do get the job done. What I mostly liked from the speakers is the ability to take them on the go , and that is made possible beacuse of its usb powered feature.
