Replacement cables for balanced earphones
Calling all balanced output enthusiasts
The new RC-MMCXB adopts 2.5mm 4-pole plug. With its separate Left/Right channel wires and separate +/- signal transfer, the RC-MMCXB enables balanced operation for your earphones. When connected to a balanced headphone amplifier (such as the Fiio AM3), RC-MMCXB can greatly enhance channel separation as well as markedly increase the signal to noise ratio. This results in a wider sound stage and more controlled, textured bass-perfect for balanced output enthusiasts.

The details matter
The plug adopts the one-step CNC machining and precise grinding technology, together with the zircon sand blasting and anodizing processing method, which ensures a smooth and sleek hand feeling. Meanwhile, the 45°lines and FiiO red ring design not only gives it a beautiful look, but also increases the friction, making it easier for you to plug and unplug.
Stunning looks backed by impressive internals
The RC-MMCXB adopts PVR for the sheath and 6N oxygen-free silver-plated copper as the conductor.19 strands of silver-plated copper wires (each with a diameter>0.06mm) make up each of the 4 separate cables, which are well woven into one audio cable with separate wires for the Left/ Right channels. These premium choices of materials ensure the RC-MMCXB is highly elastic, tough against scrapes, and resistant to aging.
