The exclusive design of the closed-back HFI-780 is accentuated by the polar-silver color. Featuring all Ultrasone technologies such as S-Logic™ Plus, ULE and safer hearing, the HFI-780 is developed from the studio sector and is distinguished by a frequency response specifically tuned for DVD and gaming. Sophisticated home cineasts and music enthusiasts are overwhelmed by the impressing sound that appears as though you are listening to speakers several feet away. Foldable for compact storage. Hemi-Sync® devotees will appreciate the complete isolation of a closed back headphone when exploring their inner landscape and the "airy" lifelike performance normally found in open back designs when listening to their favorite music. Foldable for compact storage.
