In this video we show you how all Oral-B products have a feature called 'Sound Connectivity' even-though it is advertised as a specific feature on certain brushes. <br /> <br />The sound connectivity uses the Oral-B app downloaded onto an Android or iOS device and that devices built in microphone to listen out for the sound of the brush once it has been powered on. <br /> <br />When on the app will begin a timer counting the cleaning time until such time as the sound can no longer be heard. <br /> <br />The app will not launch without interaction and the phone or device with the app must be within range. <br /> <br />It is a workable but not particularly reliable option for logging your toothbrush cleaning performance.
