Sennheiser, known around the world and in virtually every professional sound studio for its reference-standard headphones and microphones, is kicking off a unique new marketing initiative. The Sennheiser Sound Tour commences on July 2, 2009, at Milwaukee Summerfest, the world's largest music festival. The promotional tour will put the company's highly regarded consumer headphones and headsets into the hands--and onto the heads--of thousands of music and technology fans, in a fun, fast-paced, light-hearted setting.

The Sennheiser Sound Tour will see two road-ready teams setting out, one heading east, one west, on a mission: to put Sennheisers on as many heads as possible. The two intrepid sextets will compete to determine which can Sennheiser-ize the greatest number of unsuspecting civilians. Oh--and did we mention that one team is composed of girls; the other of guys?

While the resultant Sennheiser-centric battle of the sexes is sure to be outrageous in person, the Sound Tour promises just as much fun online. Both teams will post their progress in sound, pictures, and video to "webisodes" on the dedicated site sennheisersoundtour.com. This in turn will link up connected sites on social-media destinations Facebook, Twitter, and YouTube, and all of these will encourage consumers and Sennheiser fans across North America and around the world to join in, even to mount a team challenge such as to Sennheiser-ize people in a particular place, specific individuals, or even celebrities.
