The noise-cancelling technology featured in these True Wireless Bluetooth Headphones allows you to suppress outside noise while using them, whether with the sound on or off. This is especially useful on an aeroplane, or when working in an open-plan office environment. The over-ear headphones are comfortably padded and adjustable. They feature a luxurious matte rubber-coated finish, with shiny gun metal trims. Featuring loud and crisp sound, for listening to music and podcasts or watching videos, and the built-in microphone facilitates easy calling, with clear sound at both ends of the call. Pair the headphones once with your device (phone, tablet or laptop), and you won’t need to do so again – they will automatically pair thereafter, as soon as you turn the headphones on, providing your device has Bluetooth mode switched on. From a full charge, these headphones will last over 20 hours in Noise-Cancelling mode, or up to 30 hours in Bluetooth-only mode. The EVA case protects your headphones while travelling, and includes a charging cable, and a 3.5mm jack audio cable, which can be plugged in to the headphone jack of your seat on a plane.
