Usually, a smaller headset automatically meant a shorter battery life. However, Cardo Wireless has created a balance between the two in their Scala 700 Bluetooth headset. The Scala 700 has 10 hours of total talk time, and 240 hours of continuous standby operation. The device is small enough o fit snugly into your ear and supplies good quality audio. It’s very easy to setup and operate. The reviewer noted that the Scala 700 is for users who want small headsets with longer battery life.
