Yongse RedBunny Mono-crystal Cu+ Silver-plated Mono-crystal Copper Core Graphene Shielding Earphones Upgrade Cable

The YONGSE RedBunny Upgrade Headphone Cable is a high-value, dual-core HiFi replacement cable designed for audiophiles seeking enhanced purity, clarity, and balanced performance from their IEMs. Featuring a sophisticated multi-layer hybrid conductor with single crystal copper (OCC), silver-plated single crystal copper, and graphene composite insulation, it delivers superior conductivity, reduced interference, a cleaner noise floor, and subtle refinements in detail, timbre, and dynamics—making it an excellent upgrade over stock cables without introducing harshness or thinness.

Ideal for daily use or critical listening, the RedBunny adds noticeable improvements in transparency, bass control, and overall smoothness, often praised for its premium feel and practical design in the budget-to-midrange category.

Key Features

• Advanced Dual-Core Conductor Design:
  • Center Core: 30/0.05 single crystal copper + 15/0.05 single crystal copper + 10/0.05 silver-plated copper — combines OCC's natural warmth and low distortion with silver-plating's speed and extension for fast transients, rich mids, and sparkling highs.
  • First Layer: Graphene composite PVC — provides exceptional EMI/RFI shielding, vibration damping, and a blacker background with minimal microphonics.
  • Second Layer: 87/0.06 silver-plated copper + 87/0.06 single crystal copper — coaxial outer shielding enhances signal purity, reduces crosstalk, and adds body for controlled, deep bass.
• Build & Comfort: Lightweight yet durable construction with low microphonics; flexible and tangle-resistant for comfortable, long-session wear; ergonomic ear hooks (standard on most variants).
• Length: ~1.2m — perfect balance for portable DAPs, dongles, or desktop setups.
• Connectors:
  • Plug: 3.5mm single-ended or 4.4mm balanced (gold-plated for optimal contact).
  • Earpiece: 0.78mm 2Pin (standard; compatible with most modern IEMs).
• Compatibility: Broad support for popular brands like Moondrop, Tangzu, 7Hz, KZ, TRN, Hisenior, Kefine, and more using 0.78mm 2Pin connectors.

Why Choose the Yongse RedBunny Upgrade Cable?

Community feedback often highlights:

• Clean & Detailed Sound — Graphene insulation suppresses noise effectively, revealing micro-details and improving separation.
• Balanced Tuning — OCC warmth with silver-plated sparkle; tightens bass, smooths mids/vocals, and adds air without fatigue—great for bass-heavy or neutral sets.
• Practical Build — Feels premium and lightweight; low microphonics, good handling despite some stiffness reports; excellent value
• Reliability — Durable materials and consistent quality from Yongse's production.

It's a "no-fuss" favorite for upgrading stock cables—perceptible gains in clarity and refinement without hype.

Pairing Suggestions

The RedBunny's hybrid OCC + silver-plated + graphene signature pairs well with:

• Bass-Heavy or Warm IEMs (e.g., KZ, TRN, or CVJ models) — Tightens lows, reduces mud, and adds extension/air.
• Neutral/Detail-Oriented Sets (e.g., Moondrop, Tangzu, or 7Hz hybrids) — Enhances openness, imaging, and vocal smoothness.
• High-Sensitivity Budget IEMs— Cleaner background and dynamics on balanced sources like dongles or entry DAPs.

Versatile for pop, EDM, rock, and acoustic—suits most tunings!
