Players such as San Francisco 49ers quarterback Colin Kaepernick and Seattle Seahawks cornerback Richard Sherman are out of luck now that the NFL and Bose have struck a deal that limits what players can wear during football-related activities.

According to Sporting News' Jasmine Watkins, the league has agreed to terms with Bose that will prohibit players from using any headphones other than Bose—including Beats by Dre headphones—while they are on camera.

Per Watkins: "The restriction of other headphone usage includes preseason training camps, practice sessions, game day, postgame interviews, and it remains in place until 90 minutes after the game has ended."

Update from Friday, Oct. 10

It looks like at least one NFL team is getting hooked up with Bose headphones so they can avoid potential fines from the league. The Carolina Panthers tweeted that every player had a gift waiting for them this morning:

Update from Thursday, Oct. 9

The NFL is serious about making sure players don't wear any headphones other than Bose during the restricted periods.

According to multiple reports, San Francisco 49ers quarterback Colin Kaepernick was fined for wearing Beats by Dre headphones after Sunday's game.

Kaepernick explained why he wore the pink Beats by Dre headphones during his postgame press conference:

St. Louis Rams defensive end Chris Long weighed in on Kaepernick's fine.

Fans may wonder why something like this matters, but when the league has a sponsorship deal, the players have to abide by the rules.

The new restrictions aren't sitting well with some.

This news is especially bad for some players, like Kaepernick and Sherman, who have appeared in Beats by Dre commercials.
