Beats Fit Pro is equipped with comfortable, secure-fit wingtips that flex to fit your ear. The universal wingtip design was put to the ultimate test by athletes of all kinds so you can trust these earbuds will stay put through work days and workouts. Complete with pressure relieving vents, you can comfortably wear these earbuds all day long. Beats Fit Pro is engineered to deliver powerful, balanced sound via a custom acoustic platform that stays with you through your daily activities. A proprietary, dual-element diaphragm driver resides within a two-chamber housing, resulting in clear sound with outstanding stereo separation. An advanced digital processor then optimizes audio performance for loudness and clarity, while simultaneously ensuring clean noise-cancellation.
