Natural spatial sound.

The specially developed S-Logic technology offers spatial perception and a sound stage that is unparalleled.
What is S-Logic®?
S-Logic technology is the way in which ULTRASONE brings sound into the user’s hearing. The human ear is a complex miracle of nature. The entire ear is involved in the listening experience – including the auricle. It is responsible for ensuring that we can perceive distances and directions. This is a particular challenge when listening to headphones, as the sound is often emitted directly into the ear.
It is precisely for this reason that we have developed our patented S-Logic® technology, which includes the entire ear, including the auricle. Here, the transducers are not placed in the middle of the headphone cup, but offset forward and downward. As a result, the sound first hits the outer ear – the inclusion of the auricle anatomy in the hearing process creates a spatial perception for all common stereo sources, without any additional electronics. The result is an impressively natural sound, directions and distances are reproduced without distortion and authentically. With S-Logic® you don’t hear music in your head, but on a large stereo stage in front of you.

- 40% load on hearing

Thanks to S-Logic®, ULTRASONE headphones require about 3-4 dB lower sound pressure in order to achieve the same volume perception. This puts up to 40% less strain on the ear, which significantly reduces the risk of hearing damage.

Less hearingfatigue

With S-Logic®, the ears tire less, even during long listening sessions, so that carefree music enjoyment is possible for many hours.

Spatial sound image

Optimized, spatially improved perception of voices and instruments with stereo sound signals. Broad sound despite headphones.

Precision Dampening

S-Logic® Plus combines precision dampening with micro-acoustic reinforcement, allowing driver, buffer-board, and spatial parameters to complement one another in an optimal manner.

Maximum neutral sound

The tonal fine-tuning result in maximum neutral sound impression with the more vivid perception of voices and instruments.

Precise localization

S-Logic®EX is particularly popular in the gaming sector. The precise location option through the refined sound tuning brings the decisive advantage in the game.

wider sound stage

With the angled drivers, we create an even larger soundstage. This is often used for enjoying films carried by great soundtracks.
S-Logic3 is based on an innovative design that is reflected in a natural spatial effect. The listening experience is practically inseparable from that of professional studio monitors and, unlike loudspeakers, does not depend on the room acoustics.
The DDF is positioned in the sound field which segments the intensity of the sound. In this way, the directional medium and high-frequency signal components remain almost unchanged, while the lower medium and low frequencies are partially masked and directed and their areal exit distribution is changed, which further refines the S-Logic effect.
The spatial image appears natural, with excellent separation and clarity. Everything is evenly and appropriately positioned in the place it should. With the holographic stage, subtleties in sound elements can be realized, since information that could be lost is brought to the fore. The unique shape of the DDF is the result of a long series of tests to translate the theoretical requirements into optimized listening experiences. The center of the transducer remains largely unaffected, while the sound field of the relevant lower frequencies must flow around the DDF, which, according to Rayleigh, causes a change in the ITD effect.
