Fosi Audio Carbon12 World's First UTPT™ Pure Carbon IEM

12mm Ultra-Thin Pure Carbon Diaphragm
Carbon fiber is used in aerospace and F1 for strength and low weight. Carbon12 is the World’s first IEM with UTPT™ technology, creating a thinner, rigid diaphragm for fast transients and precise frequency response.

TC4 Titanium Shell & Forged Carbon Fiber Faceplate
The rigid TC4 titanium shell suppresses vibrations for purer sound and offers higher hardness than pure titanium for better scratch resistance. The carbon fiber faceplate gives each Carbon12 a unique look.

7.5g Lightweight IEM Fit
At just 7.5g per earbud, Carbon12 features a rounded ergonomic chamber that follows your ear's contours. Its lightweight design helps provide comfortable wear for extended listening, ideal for audiophiles.

Unique Front & Rear Chamber Acoustic Design
An open front chamber reduces the plugged-up feel of IEMs for a wider, more natural soundstage. Rear damping foam absorbs standing waves and reflections for cleaner sound.

Detachable Cable & Sound Tuning
Four-core silver-plated OFC cable is tuned for Carbon12 to reveal fine details. The included 3.5mm cable has detachable 0.78mm 2-pin connectors for 4.4mm balanced upgrades. Tuning filters let you fine-tune sound.
