Well that didn't take long.

High-end headphone-maker Bose signed a sponsorship deal with the National Football League, which bars players from wearing any non-Bose headphones during televised broadcasts. And the first person penalized from this new rule is San Francisco 49ers quarterback Colin Kaepernick, who was fined $10,000 for wearing Beats headphones in front of cameras on Sunday, according to Deadspin.

Kaepernick is no stranger to Beats. He even stars in a Beats commercial.

The ban on non-Bose headphones extends to interviews conducted throughout preseason games and during practices, as well as post-game interviews in the locker rooms. Players can't wear non-Bose headphones 90 minutes after play has ended.

It's still unclear whether Kaepernick knew about the possible fines, which were just announced Sunday. It's also unclear whether he'll pay the fine, or whether he'll let Beats handle it.

Either way, wearing the headphones seemed to work. The 49ers beat the Kansas City Chiefs at home 22-17.
