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.
