Signature QUANTUM

ULTRASONE Signature QUANTUM

Why true sound comes at a price.
The Signature QUANTUM is no ordinary headphone; it is a conscious choice for uncompromising sound quality, technical sophistication, and emotional depth. Priced at 999 euros, it represents the pinnacle of the ULTRASONE Signature Series. Yet this price does not signify prestige, but rather a value that can be heard, seen, and felt in every detail.

At the heart of the Signature QUANTUM lies the new S-Logic®️5 sound system, a logical evolution of the globally recognized S-Logic®️3 technology. It delivers an exceptionally spacious, natural, and precise soundstage that is more reminiscent of high-quality speaker listening than of classic headphones. Instruments and voices detach completely from the head, gaining depth and clarity, while the ears tire significantly less. It is precisely this combination of precision and long-term comfort that makes the Signature QUANTUM a tool for professionals and a delight for audiophiles.
A key reason for this sound quality lies in the carefully matched transducers. Each driver is selected and tuned to ensure maximum channel balance and the highest transparency. This elaborate process ensures a stable, realistic soundstage in which the finest details are preserved and music can fully unfold its emotional impact. This type of quality control is time-consuming and costly—and clear proof of why the Signature QUANTUM plays in a higher league.
ULTRASONE makes no compromises when it comes to materials and craftsmanship either. All essential components are made of metal, and the ear cups are crafted from high-grade aircraft-grade aluminum. Exceptionally soft, high-quality leather materials and the newly developed FGC headband ensure exceptional comfort and perfect balance, even during long listening sessions. The Signature QUANTUM is designed not only to inspire immediate enthusiasm but also for years of use without any loss of quality.

The fact that sound isn’t created solely within the driver is also evident in the signal routing. The Signature QUANTUM comes with a high-end balanced cable featuring a 4.4-mm jack, as well as an unbalanced cable with a 3.5-mm plug and a 6.35-mm adapter. Both these cables and the internal wiring are supplied by Luminox, a highly regarded specialist in audiophile signal technology. The result is low-loss, dynamic, and absolutely authentic transmission—the prerequisite for unadulterated sound.

The overall package is rounded out by a presentation that lives up to the product’s high standards. The Signature QUANTUM comes in an elegant black aluminum case, where the headphones, with their engraved tempered glass plaques, are stored safely and stylishly. The new NAOS Micro also finds its place here, perfectly complementing the setup.

The price of 999 euros for the Signature QUANTUM does not represent a short-term luxury, but rather an investment in lasting quality. It combines state-of-the-art audio technology, high-quality materials, precise manufacturing, and professional standards in a product that does not demand the next upgrade, but inspires long-term enthusiasm.

Signature QUANTUM – a sound that stays with you.
