First of a new kind. Pulsonic is the first of a new kind - a new shaving system from Braun and a revolution in shaving technology. It has been uncompromisingly engineered to capture more hair in fewer strokes even problem hairs so you can enjoy our closest most comfortable shave ever. Sonic Pulsing Action. Pulsonic is the only shaving system on the market with a new sonic motor that powers a high frequency pulsating shaver head. At the simple touch of a button power sent to the dynamic shaver head stimulates tiny vibrations on the skin to loosen and raise problem hairs for greater cutting efficiency and a thorough and comfortable shave. Cross Cutting Technology. Thanks to the Pulsonic head the high speed dynamic movement of the shaving foils is combined with the cutting blades moving in the opposite direction. This unique movement produces a scissor like cross cutting action that cuts hair with gentle yet high speed precision for a noticeably fast thorough and comfortable shave.
