JBL became one of the first manufacturers of specialized headphones for athletes. And if other manufacturers are limited to water protection alone, JBL often goes much further, equipping its sports headphones with built-in mp3 players (useful for the pool), special magnetic fasteners, etc. It got to the point that in 2016 JBL announced the launch of a line of headphones made in conjunction with the American manufacturer of sports equipment Under Armour.


As they say in JBL, these are headphones created by athletes for athletes, so the matter is not limited to the banal protection of the case from sweat. Many representatives of the series are equipped with physical buttons instead of touch buttons, so it's easier to control headphones with wet hands. Or when the hands are in gloves. A mandatory attribute for intra-channel models has become a small rubber appendage on the end of the headphones, which plays the role of an additional retainer so that light capsules do not fall out of the ears during training. A set of replaceable ear pads, usually, includes a set of traditional silicone nozzles and additional sports nozzles with a small process-fin for improved fixation. At the same time, the Under Armour models sit comfortably in the ears, are not afraid of accidental ingress of moisture and have a good margin of battery life. And what else do you need from sports headphones?

JBL is actively experimenting with the shape, so the Under Armour lineup is not very uniform. In 2017-2018, the first in-channel models with Bluetooth connectivity were released. By the standards of 2021, they are not of particular interest. The real success came in 2018-2019 with the release of the first true wireless models, which simply had nothing to scold for. Since then, the company has been trying to produce models of exactly this format, occasionally hitting experiments. One of them was the closed overhead headphones Under Armour Train Rock, released together with former wrestler and current Hollywood star Dwayne the Rock Johnson.
