JBL launches headphones designed, tested and approved by The Rock in Brazil

After launching in Brazil a model of headphones aimed at the home office — which became routine for many Brazilians due to the coronavirus pandemic — JBL and Under Armor got together to create a new edition of the exclusive Project Rock collection: headphones Under Armor Project Rock Over-Ear Training.

Tailor-made for intense training, the model is durable and suitable for those who prioritize sessions with a lot of dedication and sweat in their daily lives. The headphones were developed in partnership with Dwayne Johnson, The Rock, an actor known for having developed musculature.

According to JBL, the novelty is made for heavy hitters, with the JBL Charged Sound providing maximum motivation and deep bass, perfected by The Rock himself. The adaptive noise cancellation feature allows fitness users to focus on their workouts by controlling ambient sound levels.
