I have the TripleFi 10s and had to replace my cable about once every year until recently when I found out about the Fiio cables. I can't say I hear a difference in sound quality from my stock cables, but their build quality and design is much better.
The first time I bought the cables I really liked it. It was a huge improvement from the stock cables that I was using. First of all, it was braid and felt a lot lighter than the old cable. They claimed that the cable was SPC but I could not tell the difference in sound but I only used my TF10s with my phone so my source was never that good. They looked really cool being silver and all so I'll give them that. Around the ears, instead of using a metal wire like the stock cables did to keep the fit, they had a plastic section that covered the cable.
So it was really nice and everything but after almost a year it still had that problem near the plug where it wears out so I decided to buy another one because it was a cheap option and it worked a lot better than the stock cables. What they didn't tell me was that they actually revised the cable to make it better. The cable was a lot more neatly braided so it was even thinner and felt lighter on the ears. The plastic that was once used to cover the area around the ears was shrunk to have a lower profile and they used a thinner plastic that was lighter around the ears but still served well to hold the fit around the ear so the wire doesn't fly around.
What really impressed me was the Fiio continued to make their product better without selling it as a newer version for a higher price. They don't even mention it anywhere at all that they updated it. The fact that they did this makes me really these cables.
Just my two cents.
