Dwayne Johnson teamed up with Under Armour and JBL to make wireless headphones that won't fall off when you work out — here's what they're like

Under Armour's new workout headphones have been approved by The Rock himself.

On Thursday, Under Armour released the UA Sport Wireless Train headphones, Project Rock edition.

Two years in the making, these are the first headphones under the actor Dwayne Johnson's Project Rock line of workout gear with Under Armour.

The fully wireless headphones are rugged, sweat-resistant, and built for high-intensity workouts like weightlifting. Under Armour says Johnson has even tested the headphones during his workouts — they passed.

The headphones cost $250 and are available starting Thursday.

Here's what they're like.

Here they are, the UA Sport Wireless Train headphones, Project Rock edition.

Johnson spent two years working with Under Armour to create the headphones.

"I prefer training in 'over the ear' headphones, but have been consistently disappointed (pissed is a better word) with every pair, from every brand that just couldn't handle my workouts," Johnson said in a statement about the new headphones.

"I thought if no one is going to design headphones BUILT FOR TRAINING, then I would," he said. "And I'd make them the best. Almost two years later, they've arrived."

The Project Rock headphones were created in collaboration with both Under Armour and the electronics company JBL. They're the first pair of headphones from Johnson's Project Rock line with Under Armour.
