S-Logic Natural Surround Sound

Ultrasone’s patented S-Logic™ natural surround sound system is a revolutionary advance in how we listen to headphones. S-logic™ creates a natural three-dimensional sound field that gives the listener more depth to their music. S-Logic™ gives the listener a more lifelike listening experience and protects their hearing all at the same time.

With normal headphones you have the impression, that the music is being played in your head...

How does S-Logic work?

Without the outer ear… we would have been bear food a long time ago.

This is because our outer ear or pinnea, allows us to perceive distance and direction when we hear sounds in the real world. As sounds come into the ear, they bounce off the folds and peaks of our outer ear creating cues that help our brains figure out where the sound came from and how far away it is. This is very useful information for outrunning hungry cave bears and also when listening to your favorite music through speakers or headphones.

Ultrasone headphones with the patented S-LogicT Natural Surround Sound Technology give a 3-dimensional sound impression

Ultrasone headphones with patented S-Logic™ are the first headphones to utilize your entire ear, including the pinnea, in the listening experience. Through the use of decentralized driver positioning, S-Logic™ headphones aim the sound at the pinnea instead of directly down the ear canal. The sound does not go directly down you ear canal as with conventional headphones, but instead filters off the outer ear as you listen. By doing this, your perception of distance, depth and instrument placement are greatly enhanced. You can hear the mix exactly as the engineer heard it in the studio.

The S-Logic™ system does not use any DSP or other computer aided tricks. All you need to enjoy Ultrasone headphones with S-Logic™ is your favorite music or movie and your ears.
