What Reviewers Are Saying
SOUND QUALITY PERFORMANCE 50/100
The supplied review material only poses the question of whether the Cypher can offer deeper bass, wider imaging and greater detail than the HD600; it does not provide listening conclusions. There is not enough reviewer evidence here to characterize its tonal balance, technical performance or musical presentation.
Bass
50/100
The review headline raises deeper bass as a point to investigate, but supplies no finding on extension, control, impact or texture.
Midrange
50/100
The supplied material mentions natural tone as a question rather than a conclusion. Reviewers provide no direct assessment of vocals, timbre or midrange presence.
Treble
50/100
The supplied review extract says nothing about treble extension, smoothness, air or fatigue.
Resolution Detail
50/100
Greater detail is presented as an open question in the headline, not a reported result. There are no listening observations on separation, transparency or low-level retrieval.
Soundstage Imaging
50/100
Wider imaging is identified as a comparison point with the HD600, but the provided text offers no verdict on stage size, placement or image stability.
Dynamics
50/100
The reviews say little about punch, transient attack, macro-dynamic swing or microdynamic expression.
Assessments of Build Quality, Usability, and Overall Propositions.
Comfort Fit
50/100
The supplied review excerpt contains no comfort or fit impressions. Although the specifications list a 411g weight and memory-foam pads, they do not establish long-session comfort.
Build Quality
50/100
The specifications describe aluminum earcups, a steel-and-carbon-fiber headband, and lambskin lining, but reviewers provide no assessment of construction quality, durability or finish.
Features Usability
86/100
The Cypher has a 1.5m braided copper cable with dual 3.5mm cup connectors, plus magnetically mounted pads. These are practical serviceability and cable-replacement conveniences for a wired open-back headphone, though the supplied review contains no hands-on usability comments.
Value for Money
85/100
At $399, the Cypher is positioned against established mid-priced open-back models such as the HD600, according to the review headline. None of the supplied material reaches a conclusion on whether its performance justifies that price.

Manufacturer's Description — THIEAUDIO
A Flagship Comeback
THIEAUDIO is a name revered among audiophiles, representing a zero-to-hero story and a Robin Hood-inspired vision to redefine the audio industry’s price-to-performance ratio. The Cypher marks THIEAUDIO’s return to premium headphones, combining years of engineering experience into a modern-heritage design with an industry-leading reference sound signature.
Decade of Acoustic Innovation
From a small DIY-enthusiast brand to a renowned professional audio name, THIEAUDIO has maintained a singular mission: redefine audio performance and value. The Cypher is the culmination of over a decade of acoustic engineering, delivering high-fidelity sound to both professionals and audiophiles.
Precision-Engineered Dynamic Driver
The Cypher features a newly developed 50mm dynamic driver with a 20-core N45 magnetic array and semi-crystalline polymer-rubber composite diaphragm. A high-tension copper-aluminum composite voice coil ensures exceptional responsiveness and precise audio resolution under variable loads.
Reference-Class Tonal Signature
Years of audio perception research and analysis of the world’s top headphones have culminated in the Cypher’s reference tuning. It features powerful, controlled bass, a neutral midrange, and accurate treble. This ensures an honest and precise reproduction of music as mixed and mastered.
Deep, Articulate Bass & Neutral Midrange
The bass shelf delivers sub-bass extension with clarity and impact, while the flat midrange reproduces vocals and instruments with reference-grade neutrality. The treble is engineered for pin-point accuracy and natural decay, offering airy, detailed highs.
Immersive Open-Back Soundstage
As an open-back headphone, the Cypher delivers an expansive soundstage with lifelike spatial imaging, recreating every sonic detail for immersive listening.
Precision-Machined Aluminum Build & Featherlight Premium Comfort
Crafted from CNC-machined single-block aerospace-grade aluminum, the earcups provide a rigid, resonance-free structure with precisely tuned internal acoustic chambers for clean, natural sound and a spacious presentation. Paired with a stainless steel–carbon fiber headband and genuine lambskin trim, the design achieves a lightweight, pressure-free fit, ensuring lasting comfort for extended listening sessions.
Soft Velour Ear pads with Memory Foam Comfort
Velour ear pads with memory foam provide breathable, fatigue-free comfort. A magnetic mounting system allows easy replacement or customization of pads, offering perfect balance of acoustic isolation and plush comfort.
Professional 1.5-Meter Braided Audio Cable
This 1.5-meter (4.9ft) premium cable features a durable nylon-braided exterior that reduces tangling and microphonics while ensuring clean signal transmission. With 3.5mm and 6.3mm gold-plated connectors and a detachable design, it offers wide compatibility across portable and desktop setups, with easy upgrades and replacements.
Professional-Grade Reference Tool
Engineered for musicians, audio engineers, audiophiles, and gamers, the Cypher offers precision, clarity, and immersive realism. It combines a revolutionary dynamic driver, premium materials, and a reference-grade tonal signature, setting a new benchmark in headphones.
