JBL UA True Wireless Flash


The JBL UA True Wireless Flash earbuds deliver strong audio performance and excellent exercise-focused features.

Powerful bass-forward but balanced audio performance. Solid mic clarity. Strong battery life. Waterproof. Includes one year premium membership to MapMyRun.

JBL Under Armour True Wireless Flash review: Wet and wireless


With the help of audio manufacturer JBL, Under Armour's true wireless earphones are a decent, but flawed, effort

IPX7-certified water resistance ; Sporty, rugged design ; Decent battery life

Sound lacks refinement ; Charging case is bulky ; Fit isn’t very secure

However, at this price, they’re far from perfect, with sound quality and a fit that I’d expect to be much better for the money.
