STAMFORD, CT – OCTOBER 29, 2020 – JBL and Under Armour have reunited to launch the latest edition of the UA Project Rock headphone series built for the hardest workouts: the UA Project Rock True Wireless X – Engineered by JBL.

Personally tested and approved by Dwayne Johnson, the UA Project Rock True Wireless X offers a completely cable-free experience designed for the grind of training. Outfitted with UA’s IPX7 sweat and waterproof technology and Antibacterial Sport Flex Fit ear tips, these headphones are made to withstand the most challenging workouts while fitting comfortably snug to limit background noise. JBL Charged Sound pumps out rich bass for maximum motivation, while Passive Noise Cancellation decreases distraction and increases focus.

With Fast Pair and Bluetooth 5.0, athletes can quickly connect their device and make calls or listen to music on either bud independently without the worry of switching or missing a connection. Plus, users will always experience crystal-clear calls with dual beamforming mics and wind-blocking technology. Long lasting, with a total battery life of 50 hours (10 hours in the earbuds themselves, plus 40 additional hours with the rugged aluminum charging case) and USB Type-C speed charging capable of a full charge in 2 hours, these headphones are perfect for extensive training throughout the month..

UA Project Rock True Wireless X also features Bionic Hearing Technologies – TalkThru and Ambient Aware. With TalkThru Technology, the music volume is lowered, and speech is amplified for quick conversations between sets. Ambient Aware, however, delivers a more immersive music experience with increased ambient sound for safety while outdoors.

“We are so excited to continue our relationship with Under Armour in announcing the UA Project Rock True Wireless X, further growing our line of sport headphones,” said Pascal Van Laer, Vice President and General Manager, Headphones and Wearables at HARMAN. “By pairing our signature JBL Charged Sound with Dwayne Johnson’s exclusively tuned sound curve for even bolder audio with rich bass, these high-performance headphones are guaranteed to impress the toughest athletes.”

“At Under Armour, we understand the importance of durability, comfort and world-class audio when it comes to headphones,” said Brian Pitstick, Director of Strategic Partnerships at Under Armour. “The new UA Project Rock True Wireless X will be a perfect partner on an athlete’s journey of keeping fitness top of mind in the gym.”
