Targeted at business travellers, we optimized the exterior to be discreet and non-obtrusive. The study on the various sleeping positions on an airplane seat and the ear anatomy led to the eventual silhouette. It was further tuned and integrated with the acoustics volume and structural compactness. The remote control user interface was simplified into a slider selection to choose between the different NoiseGard profiles. The design of the carry case allowed the traveller to efficiently keep the head set when disembarking from the flight.
