DJ & Hi-Fi Headphones
HFI-15G 32 ohm Headphones 20Hz to 20kHz (pdf) Sound pressure level 90 dB. No other system like S-LogicTM Natural Surround Sound takes you inside your DVD movie or your PC game. If you are watching your DVD movie on a PC or with a home cinema audio set, just plug in your HFI-15G and you will be part of the movie. Due to its small size and its light weight, the HFI-15G is also ideal for mobile applications (walkmanTM, MP3-player).
HFI-500 DJ1 Now has a new part number ULT-DJ1 with S-Logic. Frequency range 10 Hz - 22.000 Hz Impedance 64 Ohm Sound pressure level 103 dB.
ULT-JD1 Open for wearing.
HFI-550 DJ closed back, Frequency range 15 Hz - 22.000 Hz, Impedance 64 Ohm, Sound pressure level 100 dB.
HFI-550 Folded for transport.
HFI-550 Open for wearing.
HFI-650-Trackmaster 75 ohm Headphones 15Hz to 25kHz (pdf) Sound pressure level 94 dB.
HFI-700 DVD closed back, Frequency range 10 Hz - 25.000 Hz, Impedance 75 Ohm, Sound pressure level 94 dB.
These superior headphones are developed from the studio sector and are distinguished by a frequency response especially tuned for DVD. Sophisticated home cineasts and music enthusiasts are overwhelmed by the extraordinary sound that appears as though you are listening to speakers meters away from your head. Also demanding PC gamers appreciate the HFI-700 because of the impressing three-dimensional sound-effects.
The low frequency ranges are being risen in order to reach the
highest possible synergies towards DSP-Systems like DOLBY HEADPHONETM and YAMAHA SILENT CINEMATM.
Due to customer enquiries and requests we implemented an additional function which enables you to fold back and up the individual earpiece without removing these headphones from your head in order to be con-nected immediately with the "outside world" again. Because of this folding mechanism, these headphones can be compactly stored and easily transported in a suitcase. Thanks to its closed construction, external noise is suppressed. You can thereby concentrate exclusively on the transferred music or spoken language you are listening to.

Professional Headphones
PROline technology and new design
PROline stands for Ultra Low Emission and means significant benefits for professional users as it is highly-developed and specially designed for professionals. The new design does not only distinguish the professional line but also allows due to more ear anatomy area a higher degree of transparency in combination with the spatial sense and understanding.
PROline technology was systematically developed for professionals as they do spend half of their lives in headphones. Most headphone drivers today convert an electric signal into an acoustical signal, producing low-frequency magnetic fields. Medical research shows that these emissions can be hazardous to our health. In response, ULTRASONE developed a special MU Metal shielding to reduce the radiation by up to 98% compared to current headphones. The patented PROline (ULE=Ultra Low Emission) technology has stood the test of international review and is recommended by technical surveillance organisations.
