Character

These lightweight headphones can follow you easily. You barely feel it when you wear them. 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, convincing with its pure and spacious sound.

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 ý itýs like being at a live concert (ýor 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-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.
