⦁ S-Logic® EX
⦁ ULE (Ultra Low Emission)



“Noble technology, materials & sound”

ULTRASONE 15 Series headphones are the first open reference headphones with patented S-LogicEX® technology.

Edition 15 draws its breathtaking sound from a completely newly developed driver system: the Gold Titanium Compound Technology GTC. 

The diaphragm consists of a gold foil and a titanium dome tweeter, which combine to produce an outstandingly transparent sound with enormous attention to detail. 

The uniquely fine sound of the Edition 15 benefits private music listening as well as work in the mastering studio. Perfect spatial imaging is ensured by the patented S-LogicEX® technology – all instruments are acoustically exceptionally clear and precise, both in width and depth.

To do justice to the quality of the sound, both visually and haptically, only the finest materials are used for Edition 15. The capsule housings are made of American cherry wood, which is also used for instrument making. The high-quality stainless steel cover is elaborately crafted and underlines the high-end claim of Edition 15.

The individual features of the wood grain make each copy of Edition 15 a truly unique piece with its serial number.

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.
