Thanks to active noise cancellation, the Live650BTNC headphones permit undisturbed musical enjoyment. The rechargeable battery powers the headphones for up to 30 hours, or 20 hours in Bluetooth mode with active noise cancellation. If the battery runs low, they can also be used with a cable. The touch buttons are located at the earcup and enable access to Google Assistant and Alexa, for instance to retrieve up-to-date infor­mation. Music playback is also easily con­trolled via these buttons.
