This set includes one red left, one black right and the original black left. Currently the red left and black right are synced as a pair. I have had these about two years, the red side about 1 year. (The black left battery just got super dead after only about a hour of use) Recently bought new beats so time for these to find a new home. Will include a charger as well. These are currently working but I cant guarantee the time of battery and will not take returns. Has been removed from iCloud account and reset.
