How do you get guys to upgrade their disposable razor to Gillette's MACH3 Sensitive? You take the world's best soccer player, put his head in a box, and recreate an entire season's worth of conditions on his face, obviously.
And how do you get a guy to feel a shave without him ever lifting a razor to his face? 3D sound technology, obviously. Watch/listen to the binaural film below. With headphones, please.
