The Ultrasone HFI-2200 are foldable, open-back headphones with aluminum nameplates with natural colors and extraordinary sound. Technologies include S-Logic Natural Surround Sound, MU Metal shielding (ULE-technology), and safer hearing.CharacterThe open-back HFI-2200 headphones with Ultra Low Emission (ULE-technology) offer the finest 3-dimensional sound reproduction. Specifically designed detachable velvet earpads will comfort your extensive listening hours. The HFI-2200 is the only Ultrasone HFI model with detachable cable. The natural colors concept is unique and emphasizes the high profile and listening pleasure.ULE-technologyTo 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 SoundThrough 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.S-Logic PlusS-Logic Plus is the enhanced version of the S-Logic System. The specific acoustically designed earcups of the 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 hearingS-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. |
