Character You prefer open-back headphones? Using the same stiff titanium-plated drivers as PRO 750, the PRO 2500 model provides the most airy sound within the complete PRO line due to its open-back design. Accuracy and the finest sound reproduction are guaranteed for everybody who does not wish a closed-back system. ULE-technology & PRO design PRO headphones have Ultra Low Emission (ULE) technology with significant benefits for professional users. PRO headphones also have a unique design; the PRO appearance not only distinguishes the professional line but also allows a higher degree of transparency in combination with the spatial sense and understanding, due to more ear anatomy area. To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal that you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review and is recommended by technical surveillance organizations. Ultrasone originally developed the ULE-technology for professionals as they spend half of their lives in headphones. But due to grand requests the, ULE-technology has now been integrated in other Ultrasone headphone lines. S-Logic Natural Surround Sound Through the S-Logic Natural Surround Sound the usual headphone sound will be moved out of the head into the room around you. The sound is no longer locked in, but appears broad and detached. Directions and distances can be heard and perceived--it's just like being in a live concert. For this new technology, additional equipment is not required. Take a pair of Ultrasone headphones plus your sound device and you will be ready for the 3-dimensional sound enjoyment. Safer hearing S-Logic does not only create a Natural Surround Sound. S-Logic allows, at the same time, a reduction of sound pressure levels by up to 40% (3-4 dB) for the same loudness sensation. This may reduce the risk of hearing damage while ensuring hours of fatigue-free listening. However, Ultrasone generally advises not to listen to music at high volumes to prevent hearing damage. _________________________________________________Retrostar Music|Promote Your Page Too Buy with confidence from Retrostar Music.
