I did try some of FiiO's original silver plated cables in the past and microphonics was unbearable, even worse than Ref8 cable. That's one of the reasons I stayed away from them, but it was in the past. Not sure if they updated the design based on a feedback from others. How is the microphonics of this new cable, when it rubs against your shirt?
@srinivasvignesh : Linum BaX cable has a good pair up synergy with Westone iems, their mmcx connectors fit snugly, and the cable itself is super thin. They also offer Super BaX, but BaX is also good enough. Of course, if you find a local cable maker, they can re-terminated the new Westone SPC cable to 2.5mm TRRS balanced, and you can use adapters to go to 3.5mm or 4.4mm, for more flexibility.
