⦁ S-Logic® Plus



“Airy, Balanced, and Spatial Audio”

Dynamic, open over-ear headphones with S-Logic® Plus technology designed by a German manufacturer.

The Eleven headphones enrich the portfolio as dynamic hi-fi headphones with an open design. It is elaborately handcrafted in our manufactory at Gut Raucherberg near Lake Starnberg.

The circumaural design features an airy, detailed sound with excellent spatial separation, offering a perfect enjoyment of a wide variety of entertainment & music – from classical and jazz to rock and pop.

At the core of the ULTRASONE Eleven headphones is a 40 mm driver with TruTex bio-cell-fiber composite diaphragm. The headphones are also equipped with neodymium iron boron magnets.

The balanced frequency response ranges from 6 to 42,000 Hertz, the maximum sound pressure level is 94 dB. The headphones reproduce every nuance of sound authentically, and your favorite music will sound with impressive spatiality and airy lightness.

The patented S-Logic® Plus technology ensures particularly spatial sound. A decentralized arrangement of the sound transducers involves the outer ear in the listening process, creating an overwhelming sound stage.

S-Logic® Plus technology allows less sound pressure to achieve the same volume perception. This prevents hearing damage and also prevents symptoms of fatigue during long periods of use.

ULTRASONE ULE (Ultra Low Emission) technology and the associated MU metal shielding also minimize magnetic radiation by up to 98% compared to commercially available headphones.

In addition to the open design, which allows better air circulation, the velvety-soft, replaceable velour ear pads provide even more wearing comfort. The all-aluminum headband guarantees a secure but comfortable fit and also sets visual accents.

The elegant look is defined by solid walnut earcups. In addition, the hi-fi headphones are extremely robustly constructed so that their brilliant sound will accompany you for many years.

Running-In Period

These headphones require a running-in period to operate at their best.

They will run themselves in naturally after several hours of listening time.

If you want to speed up the process, we recommend playing very bassy music through them for at least 24 hours at medium volume levels.

This will stabilize the speaker drivers and allow you to get the very best out of your headphones.


Noble technology, noble materials, noble sounds.

Open reference headphones with patented
S-LogicEX® technology.

ULTRASONE defines a new standard for luxury headphone products.

Why did we develop this line-up?

We knew headphones would have potential to be far more than perfect companions to enjoy music on the road. Headphones certainly have the ability to give a new eye and ear-opening experience.

With Edition 8 in 2008, ULTRASONE also presented the first mobile high-end headphone device in the entire market, defining new standards in sound, passive noise-canceling, weight, and comfort, combined with stunning optical and mechanical qualities. This had not been accomplished ever before.

With ULTRASONE options for individualization, you can select unique masterpieces to your specific wishes.


The innovative S-Logic® technology incorporates the auricle into the sound image through specially developed earpiece geometry. This creates a unique listening experience, just like in a recording studio, which is also easy on the ear.

With S-Logic® you don’t hear music in your head,
but on a large stereo stage in front of you.

ULE – Ultra Low Emission

Dynamic drivers generate electromagnetic radiation during operation. Ultra Low Emission Technology was developed to reduce electromagnetic radiation.
