Ultrasone HFI-780 - Pure Animation
The exclusive design of the closed-back HFI-780 is accentuated by the polar-silver colour. 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 cineasts 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™.

Ultrasone - ULE-technology (Ultra Low Emission) - MU Metal shielding
Most headphone drivers produce low-frequency magnetic fields as they convert an electrical signal into the acoustical signal that we hear as music. Ultrasone has developed a special MU Metal shielding that we call ULE (for Ultra Low Emissions) to reduce this radiation by up to 98%, compared to conventional headphones. This technology has withstood the test of international review and is recommended by technical surveillance organizations. Ultrasone originally developed ULE-technology for PROfessionals, since they spend half of their lives in headphones. But due to overwhelming consumer demand, we are pleased to offer ULE in the other Ultrasone lines.
Some more information about electro magnetic radiation: Electronic equipment emits low/high frequency magnetic/electric radiation, which is also called Electro-Mag. Electro-Mag is assumed to be harmful to our health. This is proved by medical research all over the world.
In order to protect health of people working within an electrically surrounded environment, clear limits about the maximum radiation emissions have been occasionally defined. For example in the TCO '99 for the allowed magnetic emission of computer screens, in a distance of 30 cm, a maximum of 200 nT (nanoteslas) is the upper recommended limit. Recommendations for the low-frequency magnetic emissions in case of headsets and headphones are still pending or are not really in the focus of importance yet. This is quite surprising as every user is carrying this very emissive equipment directly on his head! Nevertheless, we note a rapidly increasing demand for shielded headphones and headsets.
Within a research of 60 current headsets (1999 - 2000) ULTRASONE found out, that the average magnetic field emission of headsets is more than 1000 nT with a peak maximum of 2100 nT - on average. This is more than four times the maximum, recommended for computer screens in TCO '99;i irresponsible cases show even more than ten times the maximum! The developed and patented ULE-technology from ULTRASONE brings magnetic field emissions of headsets and headphones down to less than 90 nT.
