COZOY D2 Earphone

The COZOY D2 is a dual dynamic driver in-ear monitor (IEM) built around a 10mm graphene full-range driver and a dedicated 6mm beryllium sub-bass driver, joined by a physical crossover. The result is a balanced, easy-to-drive sound with deep bass, natural vocals and precise imaging for both music and competitive gaming.

The Birth of "D2"

The letter "D" is named after Dynamic — the very essence of the dynamic driver. The number "2" represents our sophisticated dual dynamic driver engineering. Together they stand for a "Second-to-None" (D2) listening experience.

Features

10mm + 6mm Dual Dynamic Drivers

The COZOY D2 uses a physical crossover with a side-by-side driver layout. The 6mm beryllium diaphragm is dedicated to the low frequencies, delivering deep sub-bass extension, fast transients and punchy power. The 10mm graphene composite diaphragm — built on a dual magnetic circuit and dual cavity design — handles the full range, offering exceptional clarity, precise imaging, delicate vocals and a seamless high-frequency transition.

Marble-Inspired Faceplate

Crafted with a premium PVC faceplate, the colours and textured patterns are inspired by the natural beauty of marble. In Eastern culture these organic veins symbolise the harmony of Yin and Yang and the philosophy of "Dao follows nature"; in Western culture, marble is a timeless symbol of eternity, uniqueness and minimalism.

Medical-Grade 3D-Printed Resin Shell

The D2 shell is produced in-house using 3D printing and medical-grade resin. Advanced ergonomics prioritise an effortless, comfortable fit while the internal geometry is meticulously engineered to optimise acoustic tuning — letting you immerse yourself in your own personal soundscape for hours.

Balanced, Easy-to-Drive Sound Signature

The D2 delivers deep sub-bass with power and impact, clean and pristine mids that keep vocals natural and centred, and a refined treble that stays smooth without being bright or fatiguing. It is incredibly easy to drive and universally appealing to audiophiles — feel the raw energy in EDM, pop and rock.

Precise Imaging & Gaming Positioning

Exceptional channel separation creates a natural soundstage with accurate audio positioning. Powerful low-end punch brings gunfire, footsteps and strikes to life, while natural vertical imaging lets you pinpoint the exact direction of subtle cues — an exhilarating edge in competitive gaming.

Interchangeable 3.5mm / 4.4mm OCC Cable

The D2 ships with a hand-woven 0.78mm 2-pin cable made from silver-plated single crystal copper (OCC). An innovative interchangeable plug design offers both 3.5mm and 4.4mm options, enhancing channel separation and delivering a transparent, brilliant presentation across all your source devices.

Three Ear-Tip Sets for Personalised Tuning

Fine-tune the sound to your taste with three included tip types:

• Bowl-shaped tips — cleaner sub-bass, bright transparent highs and a wide, spacious soundstage.
• "07" tips — a fuller bass atmosphere, thicker mid-range vocals and excellent treble extension.
• Memory foam tips — high isolation for deeper sub-bass, warmer tone and closer vocals; ideal if you are sensitive to treble.
