  Pure Carbon Diaphragm

  Widely used in aerospace and Formula 1, carbon fiber combines exceptional strength with low mass. Fosi Audio’s proprietary UTPT™ technology overcomes traditional thickness limitations, creating an ultra-thin carbon diaphragm with metal-like rigidity for faster transients and more accurate frequency response.

  Ultra Thin Ply Technology

  

  Easy to Drive
  Great Sound

  

  Dual-Chamber Dynamic Driver

  A low-distortion driver (THD ≤0.5% @1kHz) and precisely tuned dual-chamber design deliver a wide frequency response and spacious soundstage. Dedicated rear-chamber damping foam absorbs standing waves for cleaner sound.

  

  Easy to Drive, Great Sound

  With 37Ω impedance and 108dB sensitivity, Carbon 12 is easily driven by a dongle DAC or portable digital player, delivering high-quality sound wherever you go.

  

  Warm, Full-Bodied Tuning

  Carbon 12 delivers a natural, balanced sound with both accuracy and emotion. Fast transients and excellent detail meet slightly forward mids, creating rich, textured vocals ideal for pop and vocal-focused music.

  

  TC4 Titanium Alloy Housing Stronger Than Pure Titanium

  Carbon12’s rigid TC4 titanium housing suppresses unwanted driver-to
  shell vibrations for cleaner sound. Stronger than pure titalnium, it is also
  skin-friendly, hypoallergenic, and fingerprint-resistant.
  

  Precision-crafted through multiple processes, the housing blends a rounded interior with clean, angular lines. Beyond sound, its design and craftsmanship are equally uncompromising.

  Carbon Fiber Meets Titanium

  The carbon fiber faceplate minimizes unwanted resonance between the housing and driver for cleaner sound. Crafted through layering, stamping, temperature control, forging, and CNC machining, each piece reveals a unique natural pattern.

  
  

  Comfortable Fit

  The front chamber’s smooth curves and rounded edges fit naturally across a wide range of ear shapes. At just 7.5g per earbud, it stays light and comfortable for extended listening.

  Dual-Chamber Construction

  

  

  Front ChamberRear Chamber

  The open front-chamber design relieves the pressure of IEMs, allowing sound to breathe for a spacious, natural soundstage and lasting listening comfort.

  Dedicated acoustic damping foam in the rear chamber absorbs standing waves and unwanted reflections for cleaner, more natural sound. A diffused pressure-relief vent balances internal pressure for a more open soundstage.

  

  Silver-Plated OFC Cable

  Specially tuned for Carbon 12, the four-strand braided cable uses high-purity silver-plated oxygen-free copper for clean, low-resistance signal transmission that preserves every detail.

  

  Explore More Sound Possibilities

  Triple-tunable ear tips in three sizes adapt to your ear shape, letting you pick the bass response you like best.

  

  Nozzle Tuning Foams

  Includes low-, medium-, and high-density nozzle tuning foams, easily replaceable with the included tweezers. Higher density softens the upper treble, while lower density adds more brightness.
