“Simply excellent”

Whatever we do at ULTRASONE, we continue to focus on doing it better with only the highest standards inspiring our strive for perfection. 

The new Signature MASTER marks a new milestone in ULTRASONEs professional flagship model. In the third generation, we have raised the bar once again in both standards of sound and design. 

Handmade by ULTRASONE at Gut Raucherberg, Germany, the Signature MASTER looks, feels, and sounds one step closer to perfection and outperforms its heritage, the edition 9 and the Signature PRO.

It is recommended for noisier environments thanks to its closed-back design. External, ambient noise is reduced while sound can’t leak out. The MASTER’s drivers are decentralized with the new DDF technology of S-Logic3 to achieve the most spatial sound signature possible. As a result, the music appears “in front” on center stage.

But this is not all that is special about the Signature MASTER. Its Safer Hearing technology allows you to hear at up to 40 % less sound pressure levels in unlimited hearing sessions with unknown clarity and analytic transparency. 

Improve your Mastering results by using this MASTERpiece. High-end through and through: 

Only high-quality materials are used in the Signature Master headphones. The Nameplates are genuine gold plated. The earpads and head pads are covered with the finest sheepskin leather, giving this model that certain something that elevates it to a truly high-end set of headphones.

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.

SIGNATURE Series for Professionals

In the early years, it became obvious that in addition to offering our technology to demanding music enthusiasts, it would also be beneficial to offer ULTRASONE products to professionals.


As ULTRASOUND already offered amazing listening experiences, also more and more imperfections in existing recordings suddenly were audible.

In 2000 ULTRASONE expanded the business structure to professional users; recording engineers, DJs, mixing and mastering engineers, and performing artists. As it makes no sense for professionals to work with less-than-perfect equipment, while the audience around the globe has better equipment.

In 2012 ULTRASONE created the famous Signature PRO, a combination of edition 9 sound signature and the professional design features of our PRO-Models. It offered the best possible sound for professional users.

Today, Signature Master has taken over this position in the market.

S-Logic 3 technology, ULE shielding, and even finer tuning.

The Professional Series is quite easily the best tool for the studio, at home, or on the road.

Undisturbed Work

With our passive noise cancellation, the Signature Master offers the best conditions for hours of concentrated work.

Selected Materials

The enclosed housing is made of extremely resistant plastic, which can withstand even the toughest studio use without any problems. Genuine merino leather ensures comfort at the highest level.

Tools with Style

The Signature Master’s genuine gold-plated nameplate identifies its owner as a true audiophile gourmet with a sense of lasting value.


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.


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