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 their return to premium headphones, combining years of engineering experience into a modern-heritage design with an industry-leading reference sound signature.

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.

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 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.

Articulate Bass and 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.

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. 

Premium Build and 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.

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 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.
