Pairs of Beats by Dre headphones have showed up on many of the coolest ears on the planet, because it’s good for the brand to put them there. Lady Gaga and Justin Bieber have even had their own branded earbuds. (You might not think Bieber is cool, but his name does sell stuff to tween girls.) Getting the cans on to the heads of pro athletes is also key, which is why a wonderfully sneaky guerilla campaign began with the company slipping headphones to some highly visible Olympic athletes off-campus…despite Panasonic spending nine figures to be an official electronics sponsor of the Games. The International Olympic Committee is not thrilled with the good doctor.
