The new HFI-450 includes the sound technology of the legendary HFI-15G. The closed-back HFI-450 shows its high profile with powerful and very clear sound reproduction which is highly appreciated by all Ultrasone users. These headphones have been specifically developed for all Ultrasone fans who are looking for an entry model for home and studio application. Of course this model also includes the patented Ultrasone S-Logicâ„¢ Natural Surround Sound Technology.


S-Logicâ„¢ Natural Surround Sound
Through S-Logic™ Natural Surround, the sound moves out of your head and into the room around you. Consequently, the music is no longer confined, but breathing once again, spacious and organic. Direction and distance are more easily perceived – it’s like being at a live concert (…or in the studio). No additional equipment is necessary. So with just a pair of Ultrasones and your favorite audio device, prepare yourself for genuine 3-dimensional enjoyment!

Safer hearing
S-Logicâ„¢ does not only create a Natural Surround Sound. S-Logicâ„¢ 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.
