The earbuds were first leaked in a beta of iOS 16.4. Code-named 8214, the Beats Studio Buds+ will purportedly feature media controls for play/pause, audio sharing, automatic device switching, "Hey Siri", active noise cancellation, and transparency mode.
It's unclear if they will replace the current Beats Studio Buds (currently on sale for 33% off) or if they will be sold alongside them.
