From right to left, the inner ring features the sound mode button to choose between the hifi and bass mode. Next up is the power button. Pressing the power button for 1 second when the headphones are on will engage the bluetooth pairing mode. The Bluetooth indicator will pulse blue to indicate the pairing mode. It will illuminate continuously when connected to a bluetooth device. The power indicator will lit green when turned on. When switched on and disconnected from a battery charger, the remaining battery level will be displayed. Next is the USB type C input connector. To finish off there’s the ANC button to switch between the 3 different levels of active noise cancellation. A sweet male voice supports every change.
