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 the S-Logic™ Natural Surround Sound the usual headphone sound will be
moved out of the head in 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!
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.
