This white cable (silver), is the default for some Oriolus (south-east Asia). I guess yours are the PW5 (copper), default elsewhere. In that case, i'm not sure how will it be/sound if you reterminate it.
I just cut, and replace the old plug/jack with a better quality one (better conductivity). Some shops offer service for reterminating cables, here it costs around 10-20 USD..
The Oriolus is at home, and I'm away at the moment.
I've tried the Oriolus with stock cables (white), and the reterminated one side-by-side. And the difference is quite apparent. The latter sounds rather significantly improved, better overall. Maybe it depends on the jack/plug as well. You should experiment which suits you best.
Also tried the standard PW5 copper, compared to the white silver cable, it sounds a bit different. The bass is thicker, but the treble, clarity and soundstage are a bit less than. But now that I've reterminated the white cable, it sounds better than the PW5 and the white before. The bass is even bigger, mids and treble clearer, but the soundstage is not much different.
