Experience the complete isolation of closed-back headphones & the honest sound of open ones. The high class gold-plated drivers of the HFI-680 are very sensitive & provide a maximum of transparency. ULE-technology To understand what ULE-technology does, you need to know that most headphone drivers produce low-frequency magnetic fields as they convert an electric signal into an acoustical signal you hear as music. In response, Ultrasone developed a special MU Metal shielding (ULE-technology) to reduce the radiation by up to 98% compared to current headphones. The ULE-technology has stood the test of international review & is recommended by technical surveillance organisations. Ultrasone originally developed the ULE-technology for professionals as they do spend half of their lives in headphones. But due to grand requests the ULE-technology has now been integrated in other Ultrasone headphone lines. S-Logic Natural Surround Sound Through S-Logic Natural Surround, the sound moves out of your head & into the room around you. Consequently, the music is no longer confined, but breathing once again, spacious & organic. Direction & 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 & your favorite audio device, prepare yourself for genuine 3-dimensional enjoyment! S-Logic Plus S-Logic Plus is the newest advancement in the S-Logic Natural Surround System, squeezing the BIG S-Logic soundstage found in our PRO series headphones into the more streamlined ear-cups of select HFI & DJ models. S-Logic Plus profits directly from innovations developed for our flagship Edition range, the ultimate headphones for critical listening. This sophisticated new technology combines precision damping with micro-acoustic reinforcement, allowing driver, buffer-board, & spatial parameters to compliment one another in an optimal manner. So the acoustically redesigned ear-cups of these new models & their tonal fine-tuning result in a most neutral sound impression, including more vivid perception of voices & instruments. 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 d B) 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.

New open-backed headphones with titanium-plated drivers, velvet ear pads & Neutrik connectors feature an airy & transparent sound Ultrasone Inc. announced the only open-backed headphone in its legendary PRO Series, the PRO 2900. For the first time ever, Ultrasone is releasing both a standard, single cable version & a balanced, double cable version of a pair of headphones. With the PRO 2900, Ultrasone has struck a balance between powerful & accurate sound production, with the airy & natural sound characteristics of an open-backed headphone. Balanced versus Single Cable Headphones While standard, single cable headphones are commonplace in most pro audio & audiophile applications, a balanced headphone coupled with a balanced amplifier offers unique advantages over the former such as increased audio performance due to a doubling the slew rate & voltage swing power, while reducing distortion components & eliminating crosstalk. The end result is decreased distortion & ultimately superior audio performance. To achieve this paragon of headphone fidelity, balanced headphones must be paired with a balanced amplifier (4-channel amp with 2 inverted positive channels) that instead of using a common ground, uses two wires per side to deliver positive & negative audio signals to each side of the headphone. PRO 2900 Features Ultrasone's PRO 2900s boast a classic black design, velvet covered black ear pads & a diamond-cut logo insignia on the ear cup. The PRO 2900 features a 40mm titanium-plated driver & a soft USC-Cable that is paired with industry leading Neutrik connectors. Ultrasone's newest headphones contain MU-Metal shielding (ULE technology) that reduce the amount of radiation directed to the listener by up to 98%, as compared to conventional headphones. The PRO 2900s also contain Ultrasone's patented S-Logic Plus technology for reduced sound pressure on the ear drum & enhanced tonal perception. This gives users the advantage of wearing Ultrasone headphones for many hours without their ears hurting. Ultrasone's PRO 2900 comes in a hard-sided carrying case along with two removable cables (one spiral & one straight) & spare speed-switch ear pads.

For a consumer, you’ll discover hidden gems you never heard before. 4. Safer hearing: S-­‐ Logic TM reduces sound pressure levels (3-­‐4 d B) up to 40% for the same perceived loudness. This may significantly reduce the risk of hearing damage -­‐ a must if you spend a lot of time in headphones. 5. Patented ULE Technology: Ultra Low Emission: Unlike other headphones, with ULE you have *radiation protection. Electro-­‐magnetic emissions are cut to Approx. 98%.
