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 twochamber housing inside the Bluetooth® earbuds, 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.Beats Fit Pro supports Spatial Audio with dynamic head tracking for immersive music, movies, and games. Dynamic head tracking uses gyroscopes and accelerometers to adjust the sound as you turn your head, for a multi-dimensional experience that makes you feel like you’re inside of it.
