Character
The exclusive design of the closed-back HFI-780 is accentuated by the polar-silver color. The HFI-780 contains all Ultrasone technologies such as S-Logic Plus, ULE and safer hearing. The HFI-780 is developed from the studio sector and is distinguished by a frequency response specifically tuned for DVD and gaming. Sophisticated home cineastes and music enthusiasts are overwhelmed by the impressing sound that appears as though you are listening to speakers meters away. Gamers are impressed by the exact sound reproduction, making the gaming world come alive. The low frequency ranges are being risen in order to reach the highest possible synergies with DSP-Systems like DOLBY HEADPHONE and Yamaha SILENT CINEMA.
ULE-technology
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 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 organisations. Ultrasone originally developed the ULE-technology for professionals as they do 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!22 Natural Surround Sound
Through the S-Logic!22 Natural Surround Sound the usual headphone sound will be moved out of the head in 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 19s 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!
S-Logic!22 Plus
S-Logic!22 Plus is the enhanced version of the S-Logic!22 System. The specific acoustically designed earcups of the new HFI models and their stereo tonal fine tuning of the acoustic reinforcing devices present sophisticated sound and technology. Due to an additional damping, drivers and the bufferboard complement one another with the new spatial sounding unit. The final result is a most neutral sound impression including optimized distance perception of voices and instruments.
Safer hearing
S-Logic!22 does not only create a Natural Surround Sound. S-Logic!22 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.
