Ultrasone HFI-680 Foldable, Closed-Back Stereo Headphones, S-Logic Natural Surround Sound

Designed for studio recording, and critical listening, the HFI- 680's patented technology provides amazing imaging & fidelity, greatly reduced ear fatigue, and safety like no other headphone brand in the world. The closed-back HFI-680's uses high-class gold-plated drivers. In combination with the design, the HFI-680's has amazing isolation, offers a spectacular open 3-dimensional balanced image with a maximum of transparency and much better damping than headphones with lower impedance which is quite important when you are mixing in the studio.

With a 5-year limited transferrable warranty, this robust playback and tracking headphone also utilizes the patented S-Logic technology.

Great Sound-The Best Listening Experience , Precision engineered and with 60 patents worldwide, S-Logic Natural Surround Sound is the only way to give you a listening experience the way you actually hear - by using the outer ear as the primary transfer mechanism. Instead of using centralized drivers that barrel audio directly down the ear canal, with S-Logic, audio reflects off the surface of the outer ear (which is usedfor 3-dimensional understanding of distance and direction). Audio "slides" into your head the way you naturally hear and allows you to hear musical nuances that you have never heard. Music sounds like the sweet spot of fine monitor speakers rather than headphones.Directions and distances can be heard and perceived -it's just like being in a live concert. For this new technology batteries or additional equipment is not required.

S-Logic Plus A more vivid perception of voices and instruments , S-Logic Plus is the newest advancement in the S-Logic Natural Surround Sound System. S-Logic Plus profits directly from innovations developed for our flagship Edition range, the ultimate headphones for critical listening. This sophisticated technology combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another optimally. This results in maximum neutral sound impression with more vivid perception of voices and instruments.

Hours of Listening Without Your Ears Hurting , S-Logic also provides a reduction of sound pressure levels at the eardrum by up to 40%. This can reduce the risk of hearing damage while ensuring hours of fatigue-free listening.

The HFI-680 also feature ULE-technology (Ultra Low Emission) - MU Metal shielding. Headphone drivers produce low-frequency magnetic fields as they convert electrical signals into acoustical signals. With special MU Metal shielding (ULE-Ultra Low Emissions) this radiation is reduced by up to 98% compared to conventional headphones.

These headphones are designed to isolate the music within the headphone as well as isolate the listener from outside sounds.
