What is the difference between Braun's Series 5 and Series 7 shavers?

The major difference between Braun's Series 5 and Series 7 shavers lies in their cutting systems and associated technologies. The Series 5 shavers are equipped with FlexMotionTec, which ensures optimal skin contact for a thorough and gentle shave. They also feature UltraActiveLift, a specialized middle trimmer that effectively captures and cuts flat-lying hairs. On the other hand, the Series 7 shavers incorporate Intelligent Sonic technology that automatically adapts to the density of the beard and provides extra power when needed. The ActiveLift trimmer in Series 7 shavers is designed to capture and cut even the trickiest hairs. Additionally, the Series 7 models offer Personalization modes, allowing users to adjust the shaver's intensity to match their preferred shave. Therefore, while both series deliver a high-quality shaving experience, Series 7 provides more advanced features for personalized and efficient shaving.
