How Can You Adjust the Sound of Headphones?

With the ULTRASONE Signature QUANTUM, ULTRASONE once again demonstrates what true innovation in professional headphones looks like. Instead of relying on traditional concepts, the development team has taken a completely new approach — answering a question many audiophiles ask:

Can the sound of headphones be changed through the cable?

The clear answer is: Yes, it can. And that is exactly where the uniqueness of the Signature QUANTUM begins.

This new ULTRASONE headphone acts like a true sound chameleon. By simply switching between different cables, its sound signature can be adjusted deliberately — without modifying the headphones, replacing components, or making compromises.

How Do You Achieve the Perfect Sound?

When using the unbalanced cable, the Signature QUANTUM presents itself as a perfectly balanced reference headphone. The sound is neutral, precise, and transparent, making it ideal for:

Studio mastering
Analytical listening
Professional audio work
Classical music where every detail matters

However, when switching to the balanced cable, the character of the headphones noticeably changes.

The sound becomes more lively, dynamic, and emotional. Bass response, spatial depth, and energy are enhanced while maintaining excellent control and clarity.

This makes the Signature QUANTUM especially suited for:

Modern music genres
Creative production work
Immersive listening experiences

In essence, one headphone delivers two distinct sound worlds.

Is This Better Than Changing Ear Pads?

What makes this concept particularly remarkable is that the sound tuning is achieved through the cable rather than interchangeable ear pads.

The reason is simple: this method is far more precise.

Cables influence the electrical signal directly, allowing for a more accurate and reproducible sound adjustment. At the same time, the headphone’s comfort, fit, and acoustic structure remain unchanged, avoiding the mechanical alterations that ear pad swapping often introduces.

A New Generation of Headphone Design

The ULTRASONE Signature QUANTUM represents a new generation of headphone engineering — flexible, innovative, and fully focused on sound quality.

It is the perfect solution for listeners who do not want to be limited to a single sound signature and appreciate technology that adapts to their preferences.

A headphone that proves how modern audio design can redefine the listening experience.
