| Enjoy hours of peaceful music listening using the Sony MDR-NC40 headphones. These noise-canceling headphones block out up to 80% of ambient noise, so you can hear details in your music at lower volumes and save your ears the stress. The lightweight headband and urethane-cushioned earpads reduce the pressure on your head, allowing you to listen comfortably for extended periods of time. The compact design makes these headphones easy to travel with, and the included twin-plug airline adapter lets you turn an otherwise noisy flight into an hour or more of relaxation. The high-quality 30mm drivers with neodymium magnets faithfully reproduce your music, whether you turn the noise-canceling circuitry on or off. One "AAA" battery gives you up to 40 hours of active noise cancellation. Available in Black only. Product Specifications:
