The Smart Quiet WS-7000NC is a wireless headset with noise cancellation enabling the user to become deeply immersed in the music experience without disturbances. Unwanted noise as it occurs in urban areas is significantly reduced. The small size of the headset could be realised by arranging the noise-cancelling microphone in parallel to the 10 mm driver. The keys of the small, intuitively controlled remote control are laid out in an easily accessible way that nonetheless avoids an unintentional pushing of buttons.
