Due to innovative technologies from Bose the QuietComfort® 3 Acoustic Noise Cancelling® Headphones reduce unwanted noise. They are mostly used wherever a great audio experience or just relaxing silence is wanted: while travelling by plane or train, at home or at work. Due to the compact design and the lower weight the headphones reach a combination of high quality sound, noise reduction and comfortable fit. Proprietary soft cushion, on ear design establishes a critical acoustical seal between headphones and ears. This enhances the benefits of the headphones and helps to provide superior audio quality. The ear cups rotate 90 degrees to fold flat for easy portability.
