This little blue speaker is the bomb or should I say BOOM! I own a JBL speaker this one blows it out of the water. The sound is crisp the bass is booming no crackling just good quality sound! The price you pay for this is well worth it. I've owned more expensive speakers and this one is just all around better! Did I mention it also can be used as a back up power cell for your phone, tablets and other devices. The box includes a charging cord and a aux cord. This speaker is well built and sturdy! I love it now just to hide it from my husband!
