The THIEAUDIO Cypher is an open-back, over-ear headphone featuring a 50mm dynamic driver with a 20-core N45 magnetic array and semi-crystalline polymer-rubber composite diaphragm. It is designed for reference-grade sound with a neutral midrange, deep bass, and accurate treble, housed in a CNC-machined aluminum build with velour earpads.
The HearWiki takeAI-condensed
The Thieaudio Cypher is a wired, open-back over-ear headphone with a 50mm dynamic driver and a warm, mid-forward tuning that emphasizes vocals and acoustic detail. Its velour pads and detachable cable add comfort and flexibility, though opinions vary on bass response and soundstage width. At $399, it targets listeners who prioritize midrange clarity and relaxed treble over deep bass or expansive imaging.

10:27I was not expecting this - Thieaudio Cypher Review
5.6/10The reviewer finds the Thieaudio Cypher to be a competent open-back headphone with a surprisingly good, midrange-focused sound, though it lacks bass and treble energy and has some comfort and quality control issues. It is compared favorably to the Sennheiser HD 650/6XX for its lush midrange, but the reviewer notes it is not for those who prioritize soundstage or incisive treble. Overall, it is a decent option for treble-sensitive listeners, but not a standout.

The reviewer finds the Thieaudio Cypher to be a well-tuned, mid-centric open-back headphone that excels with vocals and rock music, offering good build quality and comfort for its $329 Kickstarter price. However, it lacks the powerful sub-bass that bassheads desire, and the included cable is a minor letdown. Overall, it's considered a great value for most music libraries.

9:26Thieaudio Cypher Review (Gaming Focus)
The reviewer finds the Thieaudio Cypher to be a premium-feeling open-back headphone with a reference-style tuning that excels for music, particularly with vocals and detail. However, from a competitive gaming perspective, it falls short of top-tier options like the Sennheiser 560s due to less precise depth perception and occasional audio occlusion in intense moments, earning it a B- grade overall.
