JBL's X Under Armour Train is a wireless on-ear headphone that lets you exercise to your favorite beats.
While rather a tight fit, the ear cushions are Under Armour's SuperVent fabric to keep things cool and sweat resistant.
The Under Armour logo features prominently...
...because it's also a button you can push to activate a feature called TalkThru, which lets you hear people talking to you while still listening to your music.
The headband is antislip and has vents to keep things cool.
They also fold up to a more compact size.
