The Signature Fusion is the latest closed-back monitor headphone from ULTRASONE’s Signature Series.
Following the entry-level Signature Pure and the professional-grade Signature Master MKII, the Signature Fusion features a newly developed driver unit in addition to ULTRASONE’s signature acoustic technology and delivers a sound character unlike any previous ULTRASONE model. Let’s take a closer look at the features of the Signature Fusion.

01 S-Logic 3 Technology
First, when you think of ULTRASONE, you think of their iconic acoustic structure, S-Logic 3 Technology. This technology is, of course, incorporated into the Signature Fusion as well. By integrating this structure into the housing, it delivers a level of sound balance and spatial representation that other headphones can’t match. The soundstage is intimate yet offers high resolution, allowing you to hear intricate details of the instrument balance and nuances. Despite the close soundstage, the sound quality is fatigue-free, and you’ll gradually begin to appreciate its excellence once you experience it firsthand.

02 Sound Quality
The initial impression when listening to the sound is that it has a typical monitor headphone sound signature. All frequency ranges, from bass to treble, are clearly reproduced without being overshadowed. Optimized for modern music, the bass is well-presented, not overpowering, yet still provides a solid presence.
Vocals are natural with good extension and clarity, providing an easy-to-listen-to quality. The kick drum is tight with a solid impact, and the bass lines are crisp and clear. You can easily monitor where each instrument is in the mix.
This makes the sound quality particularly suitable for musicians, including guitarists and bassists, who need accurate monitoring.

03 Design & Comfort
Visually, the Signature Fusion looks almost identical to the previous Signature Series. The ear pads are made of sheep leather, giving them a soft, plush feel. The headband is made of mesh material, providing breathability.
The clamping force is slightly stronger than usual. Given that ULTRASONE headphones generally have a strong clamping force, users familiar with the brand won’t find this uncomfortable. This firm clamping ensures a secure fit, making it ideal for use during recording or live performances.

04 Accessories
The Signature Fusion comes with a hard case, a 2.0m coiled cable with a 3.5mm plug, a 1.2m straight cable, and a 4.4mm balanced cable for 4-pole connection. The hard case is sturdy, providing excellent protection for the headphones during transport or storage.

While well-known brands are great, if you want something unique and a bit more professional, consider the ULTRASONE Signature Fusion. It could be the perfect choice for those looking to stand out from the crowd.
We look forward to your orders!
