Compared to the 6th series models, where the SensoFlex head tilted only forward and backward, the Braun Series 7 features a full 360° Flex hinge system. The shaving head rotates freely in all directions, instantly adjusting to the contours of the jawline, cheekbones, and chin. This design allows for consistent and close contact with the skin without the need to change the razor's angle in hand. The construction significantly reduces overall wrist strain and prevents irritation from excessive friction on the facial curves.

At the core of the shaving system is a combination of three independent elements and an intelligent AutoSense sensor. The sensor continuously reads the density and thickness of the stubble, automatically adjusting the motor power on particularly challenging areas. The central trimmer effectively captures, lifts, and pre-trims closely lying or differently growing hairs. Then, two proprietary Opti-Foil foils cleanly cut remaining stubble at the base. This synchronization allows for effective removal of even tough, multi-day growth with minimal passes.

The practical side of the Braun Series 6 electric shavers includes a fully waterproof body, allowing the use of foam or gel, as well as shaving directly in the shower. A capacious lithium-ion battery provides up to 50 minutes of autonomous operation with a one-hour charge, and a quick five-minute session allows for rapid preparation for a single urgent shave. Moreover, Braun razors from the 7th series feature an EasyClick quick-release system for beard contouring, are equipped with an informative display, and often come with an intelligent SmartCare station for automatic cleaning, disinfecting, and charging the device.
