"One area where the Sound Blaster Jam leaves the competition in the dust is battery life. Creative claims that these headphones can last for 12 hours on a single charge but we actually got more than that. On a single charge, the Sound Blaster Jam lasted through around 14 hours of music playback before it died. This is really good."
