Character
These lightweight headphones can follow you easily. The open-back design of the HFI-15G is highly appreciated for mobile applications or as hearing aid for watching TV. This is the smallest headphone of the Ultrasone HFI line.

S-Logic™ 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 3-dimensional sound.

Safer hearing
S-Logic™ does not only create a Natural Surround Sound, it 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.
