Seeing the Beats Powerbeats Pro 2 earbuds fly off the Amazon shelves with amazing speed during this pre-Prime Day sale is only fitting. They’re designed to move quickly, with secure-fit earhooks that hold them firmly yet comfortably in place during runs, rides, and workouts of all kinds. But you’ll have to move fast to get your hands on them at their $200 Amazon sale price, because the supply is dwindling.

The sale price is $50 off the $250 list price — a return to the Black Friday low on the most workout-focused premium earbuds available from Apple’s ecosystem. But unlike their AirPods cousins, the Beats line of headphones and earbuds work equally well with Android devices as with Apple ones.

Unshakable Fit

The Powerbeats Pro 2’s secure-fit earhooks — reinforced with a nickel titanium alloy and 20% lighter than the original Powerbeats Pro — stay locked in during sprints, box jumps, heavy bag work, and anything else that shakes standard earbuds loose. Over 1,500 hours of athlete testing went into the fit, covering different ear shapes and training intensities. Five ear tip sizes are included to dial in the seal.
