G933 gives you the best of both worlds, with the option to game wirelessly or wired. Play lag-free on 2.4GHz wireless for up to 12 hours per charge without lighting or 8 hours with default lighting. Alternatively, the 3.5 mm analog input gives you the freedom to play wired—on console, mobile or PC—without using battery power.Battery life is measured at 50% of maximum volume. The rechargeable batteries are removable and replaceable and like all rechargeable batteries have a limited number of charge cycles.
