I see... I'm actually not looking at swapping the cables frequently but more of when it gets faulty. I think that due to high humidity or sweat, the cable of my black Kube 1.0 which comes into contact with the skin has already started to harden and shine. I think the next stage will be the rubber insulation crumbling, just as how my older earphones failed from experience. I see this MMCX solution as a double edge sword as all my earbuds come with fixed cable.
