The Beats Studio Wireless are a line of wireless, over-ear and noise-cancelling headphones aimed towards professionals and artists. The Beats Studio Wireless were released in 2013 as a replacement for the original Beats Studio. The Studio Wireless headphones have Bluetooth capabilities, and can be used with or without a wire. Unlike other Beats by Dr. Dre headphones, the Beats Studio Wireless have an internal battery and can be recharged for up to 12 hours of wireless audio playback. A microphone is also built into the headphones to allow phone calls to be made using Bluetooth.
