THIEAUDIO Cypher: A new premium open back headphone
The THIEAUDIO Cypher is designed with one clear objective: deliver a studio-reference listening experience through a modern flagship dynamic driver platform. Built around a newly engineered 50mm driver with a 20-core N45 magnetic array, aerospace aluminum earcups, and a carefully tuned acoustic chamber, the Cypher positions itself as a serious tool for musicians, engineers, gamers, and discerning music listeners alike. Let’s dive into everything you need to know about these headphones.
Built for reference listening
THIEAUDIO states that nearly a decade of audio perception research and analysis of some of the most respected headphones in history informed the Cypher’s tuning philosophy. Rather than chasing trends, the company set out to establish its own reference target—one intended to balance musical enjoyment with studio accuracy.
The Cypher features what THIEAUDIO describes as a 5dB bass shelf from 20Hz to 300Hz, a flat midrange, and accurate treble. This tuning approach suggests elevated bass strength compared to most open-back headphones, which could lead to a more familiar listening experience for those coming from consumer headphones.
For professionals, a flat midrange ensures vocals, guitars, pianos, and other core instruments maintain natural timbre. For gamers, precise treble and upper-mid presentation can enhance localisability and presence, helping players identify directional cues in competitive environments. The Cypher’s tuning appears to aim for a warm-neutral balance—offering bass depth and punch while maintaining clarity across the audible spectrum.
The flagship 50mm dynamic driver
At the heart of the Cypher is its newly designed 50mm dynamic driver. Dynamic drivers remain one of the most widely used transducer types in professional audio due to their reliability, full-range performance, and ability to deliver powerful output with strong bass precision. The Cypher’s driver integrates a 20-core N45 magnetic array. Stronger magnetic flux can improve driver control and responsiveness, potentially supporting faster attack and better bass precision at higher listening levels. In practical terms, this design aims to preserve punch and maintain low distortion at loud output levels.
The diaphragm uses a semicrystalline polymer and rubber composite. This type of construction typically seeks to balance rigidity and damping. A rigid diaphragm can reduce unwanted flex and improve clarity, while proper damping helps prevent resonances that might otherwise affect timbre or introduce boxy coloration. The voice coil incorporates a high-tension copper-aluminum amalgam. This design element may contribute to efficient energy transfer and responsiveness. For professional users, responsiveness is critical when evaluating transient-heavy material such as percussion, plucked strings, or electronic elements.
Designed for music and gaming
THIEAUDIO positions the Cypher as equally capable for music listening and gaming. Thanks to the open back design, the headphones present an immersive listening experience that should deliver width and depth in a variety of situations. For gaming, strong localisability can improve spatial awareness, helping players detect environmental cues. For music, refined treble strength can contribute to a detailed presentation without introducing shrill artifacts or excessive sibilance.
Professional build
The Cypher’s earcups are CNC-milled from solid aerospace-grade aluminum. This design choice serves multiple purposes. Structurally, aluminum provides durability and long-term stability. For a flagship headphone intended for professional environments, physical robustness matters. Acoustically, rigid earcup construction can help manage enclosure resonances. Uncontrolled resonances can color sound reproduction and affect clarity. By carefully machining the internal acoustic chamber, THIEAUDIO aims to enhance tonal stability and preserve the intended tuning.
The company describes the acoustic cavity as “articulate,” suggesting that internal shaping and airflow management have been optimized to support spatial depth and layered presentation. When combined with precise driver tuning, this type of chamber design may contribute to improved immersiveness and width. For listeners who value immersive playback—whether in music or gaming—the earcup design plays a critical role in shaping perceived space.
Along with a durable headphone design, the Cypher comes with a premium leather carrying case. The case is elegant and soft to the touch, and provides easy protection of the headphones and cable.
Premium materials for extended comfort
Comfort remains essential for both studio sessions and long listening marathons. The Cypher incorporates a composite stainless steel and carbon fiber headband designed to balance strength with low weight. A featherlight build can reduce fatigue during extended wear. The headband lining uses genuine Coby lambskin, which provides a soft contact surface. Paired with memory foam velour earpads, the Cypher emphasizes breathability and cushioning.
Velour earpads promote airflow, which can improve long-session comfort. They may not isolate external noise as aggressively as leatherette alternatives, but in controlled environments such as home studios or gaming setups, comfort often takes priority. THIEAUDIO’s material choices suggest that the Cypher is built for users who spend hours at a desk or workstation and require a stable, fatigue-resistant fit.
Wired connectivity for professional readiness
The Cypher ships with a premium 3-meter braided cable terminated in 3.5mm. The length of the cable is convenient for studio use. The braided cable is thick and feels very durable. That said, it’s also removable, which means you can replace it easily.
With a rated impedance of 32 ohms and sensitivity of 96dB ±3dB, the Cypher is designed to work with a broad range of sources. Dedicated headphone amplifiers and professional interfaces should have no difficulty driving it to suitable listening levels.
Unlike wireless headphones that integrate digital signal processing, the Cypher follows a traditional analog signal chain. The source device and amplifier supply the signal; the headphones reproduce it. This straightforward design can appeal to professionals who prefer direct, unprocessed playback.
Who the Cypher is for
THIEAUDIO positions the Cypher as the pinnacle of its dynamic driver development. The emphasis on driver innovation, acoustic chamber precision, and premium materials underscores that ambition. Whether you are an audio professional, audiophile, or a gamer looking for premium open back headphones, the THIEAUDIO Cypher have a lot to offer.
From its 50mm dynamic driver with 20-core N45 magnetic array to its CNC-milled aluminum earcups and lambskin-lined headband, every design element reflects its flagship status. For listeners who value wired performance, reference-oriented tuning, and durable construction, the Cypher aims to deliver a comprehensive solution. Based on its specifications and design philosophy, the Cypher stands as a compelling addition to the high-end dynamic driver headphone landscape.
The THIEAUDIO Cypher is available for pre-order on Kickstarter now, with shipping scheduled to begin in April. Early bird units are available starting at $329.
