Ultrasone Signature Pro Review | 93 Data compared

The ULTRASONE Signature PRO is a premium, closed-back over-ear headphone built like a "small tank" to endure demanding studio environments. It features exceptional craftsmanship, utilizing high-quality Ethiopian long-haired sheepskin leather for the headband and ear pads, which provides outstanding durability, comfort, and above-average ambient noise isolation. Equipped with a 32-ohm impedance, it is easily driven by mobile devices, though using a dedicated headphone amplifier is recommended to unlock its full potential. The package is highly practical, including a leather-finished hardcase for its foldable frame and two detachable cables measuring 1.5 and 3 metres. Additionally, it features a unique, patented MU-metal shielding to minimize low-frequency fields. Acoustically, the headphone delivers a highly detailed, neutral, and balanced sound signature across a broad 8 to 42,000 Hz frequency range, avoiding the sharp, metallic treble common to older ULTRASONE models. The integrated S-Logic-Plus system enhances three-dimensional spatial awareness, pushing the soundstage forward to reduce the feeling of audio being trapped "inside the head". Pros include its flawless build, incredible comfort, superb passive isolation, neutral and highly analytical sound resolution, deep bass, and a 5-year...

The Stereo.de review highlights the 345-gram, German-engineered Ultrasone Signature Pro as a €900, high-end closed-back headphone featuring exceptional build quality and a 5-year warranty. It delivers a powerful, dynamic sound with authoritative bass and crisp highs, boasting impressive acoustic resolution, though some technical merits require careful listening to fully appreciate. Conversely, the review notes that the understated design lacks the immediate, luxurious "wow factor" found in other premium headphones, relying heavily on specialized plastic despite the high price point. Furthermore, while offering excellent passive noise isolation, the firm clamping force and weight may limit comfort during long listening sessions.

The AreaDVD review highlights the Ultrasone Signature Pro as an exceptional, handmade-in-Germany closed-back headphone priced at 899 EUR that sets a benchmark in luxury audio quality. The core strength of this headphone lies in its proprietary S-Logic Plus technology, which utilizes decentralized driver placement to create an authentic, highly precise, and wide soundstage that removes the usual "in-your-head" sensation without relying on digital sound processing. Across various genres—ranging from classical music to trance—the review praises the headphones for delivering a beautifully balanced, emotional, and neutral tone, bolstered by a remarkably deep, punchy bass that never overpowers the mid-range. Furthermore, its 32-ohm impedance makes it incredibly efficient and perfectly optimized for mobile devices like smartphones. On the hardware and practical side, the review commends its referenc-level build quality, which includes premium materials like fine single-pane safety glass nameplates and hand-sewn Ethiopian longhair sheepskin leather for the padding, resulting in outstanding passive noise isolation and long-term durability. It features a robust folding mechanism and two high-quality detachable cables (1.5m and 3m) paired with a premium transport case. However, the review notes a...

The Ultrasone Signature Pro is a high-end, closed-back dynamic headphone that offers exceptional understated luxury, featuring a robust handmade design equipped with premium leather ear pads and a leather headband sourced from Ethiopian long-haired sheep. Priced at an MSRP of €888, it targets audio professionals by utilizing a 40mm titanium-coated transducer, MU-metal shielding against radiation, and proprietary S-Logic Plus technology to deliver a highly accurate, natural spatial soundstage. It features a very low impedance of 32 Ohms, allowing it to be easily driven at high volumes by mobile devices, and comes packaged in a premium faux-leather transport case with two detachable vergoldet Neutrik cables (a 3-meter 6.3mm cable and a 1.5-meter 3.5mm cable).

The Ultrasone Signature Pro is a high-end, closed-back, over-ear studio headphone handcrafted in Germany. It is highly praised for its transparent, clean audio signature, featuring a linear frequency response that makes it a precise tool for professional recording, mixing, and mastering workflows. Key strengths include its outstanding titanium-coated 40 mm transducers, an exceptionally precise 3D stereo image, and uncolored mids that immediately expose tracking errors or flaws in a mix. Furthermore, its low impedance of 32 ohms ensures a powerful, punchy drive even when connected to less powerful headphone outputs. The build quality is excellent, pairing a robust design with soft Ethiopian sheepskin leather padding on the earcups and headband, providing superb passive noise isolation for loud environments like film sets or editing rooms. Despite its professional strengths, the review notes a few notable drawbacks. The overall sound signature tilts slightly toward the treble during fine-tuning, which might require a period of adjustment for some users. While the bass response is highly accurate, ultra-fast, and excellent for analyzing basslines, it emphasizes clinical precision over heavy, bass-heavy warmth. Additionally, the substantial...
