The YONGSE GreyBunny Upgrade Headphone Cable is a premium yet affordable HiFi replacement cable favored by budget audiophiles for its lightweight design, excellent handling, and subtle yet noticeable sound enhancements. Built with a multi-layer hybrid conductor featuring single crystal copper, silver-plated copper, and graphene composite insulation, it offers superior conductivity, effective noise suppression, a cleaner background, and balanced refinements in clarity, bass control, and overall smoothness—making it a standout upgrade from typical stock cables.
Users often describe it as one of Yongse's lightest and best-behaved 2-core cables, with a premium coated finish that looks elegant (often mistaken for cloth but actually plastic-coated for reduced microphonics), and it delivers clear, well-balanced audio with good weight and thickness balance—ideal for daily portable use.
Key Features
-
Advanced Conductor & Layering:
-
Center Core: 30/0.05 single crystal copper + 15/0.05 single crystal copper + 10/0.05 silver-plated copper — blends natural warmth, low distortion, and body with silver-plating's speed, extension, and detail for fast transients and rich mids.
-
First Layer: Graphene composite PVC — advanced shielding and damping for exceptional EMI/RFI rejection, vibration control, blacker noise floor, and very low microphonics.
-
Second Layer: 16*7/0.06 silver-plated single crystal copper — dense coaxial braiding enhances outer shielding, reduces crosstalk, and adds refinement for tighter bass and smoother highs.
-
Build & Comfort: Lightweight and flexible (one of the lightest Yongse 2-core options); low microphonics thanks to the coated jacket; ergonomic ear hooks and manageable stiffness for secure, fatigue-free fit during long sessions.
-
Length: ~1.2m — practical for pocket use, DAPs, dongles, or desktop setups without excess bulk.
-
Connectors:
- Plug: 3.5mm single-ended or 4.4mm balanced (gold-plated for optimal contact).
- Earpiece: 0.78mm 2Pin (standard; fits most modern IEMs).
-
Compatibility: Excellent with popular brands like Moondrop, Tangzu, 7Hz, KZ, TRN, Hisenior, Kefine, and more using 0.78mm 2Pin connectors.
-
In the Box: Yongse GreyBunny Cable × 1 pc.
