High-end audio performance in an iconic design. Over-Ear Porsche Design Headphones PDH80 combine crystal-clear sound with unmistakably motorsports-inspired Porsche Design DNA. The shape of the comfortable, memory foam-filled earcups are reminiscent of a racetrack, and the practical metal hinge also has a racing design. The touch control panel for easy control of music and calls is integrated in the outer layer of the earcups. When fully charged, the headphones are ideal for long trips, with a play time of 75 hours. Active noise cancellation eliminates all disturbing noises, while an integrated microphone with echo cancellation ensures optimum sound quality for phone calls. With the line-in jack, you can enjoy hi-res audio as well.
