Styled in black and fashioned with athletes in mind, the Under Armour Sport Wireless In-Ear Headphones by JBL comprise a pair of Bluetooth earbuds. They offer 5.8mm dynamic drivers, a sweat-proof IPX5 design, and a rechargeable lithium-ion battery providing eight hours of use per charge.
Its in-line three-button remote, offering play/pause, volume, answer/reject, and skip-track parameters, provides universal control over iPhone and Android devices, while an on-board microphone supports phone calls. Also, these earbuds give you several sets of TwistLock ergonomic eartips intended to aid in comfort and security; with these earphones, the buds should never slip out of your ears until you choose to dislodge them. They come in various sizes to suit every ear shape. Included with these headphones are a zippered case, five sets of fit adapters, three sets of eartips, a micro-USB charging cable, and a membership to MapMyFitness Premium, an app which helps you monitor your health and workout progress.
