After introducing the Beats Fit Pro, Apple has phased out three older Beats headphones. The Powerbeats, Beats Solo Pro, and Beats EP are no longer listed on Apple's online store, and they are no longer available for purchase. Twitter users spotted the change a few hours after the debut of the new wireless earbuds.
Aside from the Beats Fit Pro, the Beats lineup you can still buy includes the Beats Studio Buds, Powerbeats Pro, Beats Pro Over-Ear Headphones, Beats Flex, Beats Studio3, Beats Solo3, and Beats Pill+.
