Beats Powerbeats Pro 2 - High-Performance Earbuds - Jet Black.

Powerbeats Pro 2 are the ultimate wireless sport earbuds with secure-fit earhooks so they don't fall out. The updated earhook is rebuilt with a super-light nickel-titanium alloy renowned in material design for its exceptional shape memory and flexibility. Powerbeats Pro 2 is the first-ever product to feature heart rate monitoring, giving athletes real-time data to help optimize their workouts. Its bespoke acoustic architecture delivers a powerful, balanced sound profile with dynamic range across the frequency curve; dual-layer drivers minimize distortion and are aligned to each earbud's nozzle for optimal sound delivery. For absolute focus, turn on Active Noise Cancelling (ANC), or listen in Transparency mode when you need to hear the world around you. Powerbeats Pro 2 offers up to 45 hours of battery life, and its redesigned case is 33% smaller than the original and is the first Beats case ever to feature wireless charging.
