Wireless headphones that are designed with impact-resistant materials, glass-filled nylon and corrosion-resistant stainless steel. They are also engineered to ensure high comfort even after prolonged use: the headband is wrapped in Alcantara - the soft covering material used in yachts and high-end automobiles, so it provides a welcome comfort designed for all-day listening. The plush ear cushions are further manufactured from synthetic protein leather. The headphones feature premium acoustic noise cancelling function that continuously measures, compares and reacts to outside noise and then cancels it with the opposite signal. They also feature a volume-optimized EQ for consistant performance at any volume and a built-in Google Assistant for controlling the music and more using just the voice. Bluetooth and NFC pairing with voice prompts make for hassle-free wireless connections, while the noise-rejecting dual-microphone system provides clearer calls even in noisy environments. Lithium-ion battery allows for 20 hours of wireless listening per charge. The Bose Connect app helps to set the preferred level of noise cancellation, unlock more features and access future updates. The headphones come supplied with 0.3m long USB charging cable, 1.2m long audio cable for music listening without battery power and carrying case. Dimensions: 180 x 170 x 81 mm. Silver colour design.
