Edition 8 Ruthenium is hand-made in Germany. Each Edition 8 Ruthenium headphone holds its own serial number to assure a distinctive identification.

Edition 8 Ruthenium incorporates stunning attention to detail in every aspect of headphone design. The outer ear cups are covered in Ruthenium. This precious metal is known for its brilliant metallic sheen and durable properties. The outer ear cups are emblazoned with a decorative clasp of noble metal.

The interior ear cups of Edition 8 Ruthenium headphones and the headband are covered in very soft genuine black Ethiopian sheepskin leather. This is the finest leather available and provides the finest isolation of any leather.

The metal headband of Edition 8 typifies latest scientific knowledge in headband design and development. This unique progression of headband design made by Ultrasone is highly developed and technical precision work; specifically engineered for the Edition 8 series. The headband is also covered with the very soft genuine black Ethiopian sheepskin leather.

Edition 8 Ruthenium comes with an exclusively manufactured bag made from smooth, fine grain Madras goatskin produced in France for storage and transportation.

In addition to a titanium plated tri-bass-tube driver, this Edition series headphone follows Ultrasone´s S-Logic Plus Technology which results in a most neutral sound impression with more vivid perception of voices and instruments. The Edition 8 Ruthenium also contains MU-Metal shielding (ULE technology) that reduces magnetic field emissions. Naturally, the Edition 8 Ruthenium headphones require the ULE technology as the exclusiveness of these headphones call for the ULE standard.

S-Logic Natural Surround Sound - To hear is like to see: 3-dimensional

Unique Yes! Revolutionary Definitely! The patented S-Logic technology is described as Natural Surround Sound System. No other digital surround system can compare with this standard. As the sound of a normal headphones will sound direct and even on both sides, the S-Logic? system pushes the sound around your head! It appears as though you are listening to speakers meters away. Even at very low levels, this spacious sound allows you to hear and listen to each and every individual sound. And on top of that, the S-Logic technology does not require additional equipment!

S-Logic Plus is the newest advancement in the S-Logic Natural Surround System.

S-Logic Plus profits directly from innovations developed for our flagship Edition range, the ultimate headphones for critical listening. This sophisticated new technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner. So the acoustically redesigned ear-cups of these new models and their tonal fine-tuning result in a most neutral sound impression with more vivid perception of voices and instruments.

S-Logic EX is a revolutionary refinement of ULTRASONE's patented S-Logic technology.

This innovation is based on a funnel-shaped arrangement for the sound transducer, oriented downwards to the front. This specific funnel-shaped structure allows the transducer to be further away from the ear and therefore results in a much more spatial forward positioning effect. The main purpose of S-Logic EX technology was to further optimise the already impressive S-Logic effect. Intensive research and many years of testing have directed in this funnel-shaped composition for the titanium-coated sound transducers, downwards to the front. These new titanium-coated sound transducers are an innovation specially adapted to this acoustic task.
