FiiO RC-78B 2.5mm Silver-plated Replacement Balanced Earphone Cable for Westone UM3XRC / W4R


Calling All Balanced Output Enthusiasts

  • Based on RC-WT1,the new RC-78B swaps the 3.5mm jack out for a 2.5mm 4-pole plug.With its separate Left/Right channel wires and separate +/- signal transfer,the RC-78B enables balanced operation for your earphones.When connected to a balanced headphone amplifier(such as the FiiO AM3),RC-78B 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.

A Little Extra Transparency makes for A Lot More Individuality

  • From the plug joint,to the Y splitter,to the earphone-side connector,the new RC-78B is wrapped with transparent polycarbonate to separate itself from the unicolor cable.Not only does this striking visual element give your earphones some character,it naturally also invites you to take a closer look with its revealing view of the insides.

Stunning Looks backed by Impressive Internals

  • The RC-78B adopts Teflon*FEP(fluorinated ethylene propylene) for the sheath and silver-plated copper as the conductor.11 strands of silver-plated copper wires (each with a diameter>0.08mm) make up each of the 8 separate cables,which are all woven into one audio cable with separate wires for the Left/Right channels.Both the straight 2.5mm plug and the CIEM connector (with a 0.78mm diameter) are made of gold-plated copper.These premium choices of materials ensure the RC-78B is a high quality cable that is highly elastic,tough against scrapes,and resistant to aging.

        Scrivendo direttamente a Fiio mi è stato detto che la nuova versione di questo cavo ancora non c\'è. Sarei disposto ad acquistare questo ma non sono certo della compatibilità con le audeze isine 10, allego foto dei connettori della cuffia sperando possiate aiutarmi a capire se il cavo può andare bene (so che il connettore è quello ma l\'incastro può creare problemi). Nel caso procedessi all\'ordine eventualmente il reso è gratuito?https://uploads.disquscdn.c... https://uploads.disquscdn.c...
