The Edition 5 Unlimited is our first closed-back headphone with the latest and innovative S-LogicEX® technology. Because of the decentralized position of the sound transducers a greater distance is allowed to the ear. Therefore it enables a much more spatial localization effect. The over-ear Edition 5 Unlimited with its high-quality materials is handmade in Germany. Ethiopian long-haired sheep leather ear pads, ruthenium coated ear cups and the unique sound precision are the characteristics of this high end headphone.
