Guess Who Banned Beats By Dre Headphones?

Keep their heads ringing.

Dr. Dre's Beats headphones are just about everywhere you look -- including your favorite rap videos -- but there's one place they won't turn up: NFL broadcasts.

The NFL recently secured a sponsorship with Bose headphones, which will prevent players and coaches from wearing any other manufacturers' headphones during televised NFL games, warm-ups and post-game interviews.

While the new deal doesn't just target Beats, the brand has been wildly popular among NFL players over the years. League stars Cam Newton, Russell Wilson and Richard Sherman have all been pictured wearing Beats during pre-game warm-ups and post game camera ops.

The NFL says, it isn't Bose that called for the ban, but a policy that the league has had in place for years.

"The NFL has longstanding policies that prohibit branded exposure on-field or during interviews unless authorized by the league. These policies date back to the early 1990s and continue today," an NFL spokesperson said in a statement issued to Recode.net on Saturday. "They are the NFL’s policies – not one of the league’s sponsors, Bose in this case. Bose is not involved in the enforcement of our policies. This is true for others on-field."

The restriction specifically applies to all television interviews during pre-season, training camp, practice and on game day. The policy will be enforced before the opening kick-off and be in effect until 90 minutes after the game has ended.

The ban doesn't restrict individual player endorsements however, like the one San Fransisco 49ers star quarterback Colin Kaepernick has with Beats, where he modeled the high-end headphones during an on-air and online commercial late last year. Players like Kaepernick just won't be able to wear non-Bose headphones during the times that the NFL laid out.

“Over the last few years athletes have written Beats into their DNA as part of the pre-game ritual,” a Beats spokesperson said to Recode. “Music can have a significant positive effect on an athlete’s focus and mental preparedness and has become as important to performance as any other piece of equipment.”
