Find out why online reviewers, top audio engineers, and cult followers value ULTRASONE products as an unmatched combination of audio and build quality that gets the job done. Hour after hour, year after year.

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.
