ArtfartI cannot vouch for their accuracy but according to Amazon...
' TFZ Series 3S improves on the original TFZ Series 3 by adopting a braided cable instead of TPU rubber. Furthermore, the resolution and soundstage of the Series 3S has improved compared to the Series 3.
TFZ SERIES 3 is designed to cater to the higher requirements of digital audio player. It has the best price to performance ratio among the TFZ series. '
ArtfartThanks for your information guys . Appreciate it. @Andy.techie I've been hearing its a little more than just colour but thanks for the input! @bipolarbear528 I did see the difference with the cables after looking them up on Amazon recently but couldn't find more info on performance, but i just looked it up again and found it. I have heard others saying its slightly improved. However the photos of the regular series 3 here on Massdrop show that they too have braided cables, so its a little confusing.
