There is a constant blue light on the side of the headphones which contain the power button. When I press the power button (or hold it) it shows the lights which tell me how much power is left. When I press ANC, the blue light begins flashing. If I hold ANC, the blue light disappears. The entire right side of the headphones (volume side) will do nothing when interacted with. The audio jack works, but does not turn off the headphones. Plugging in the headphones has no noticeable effect.
