Thanks for you answer! I have also received mine from that seller yesterday and everything is good. Very happy with my purchase for that price.
However, coming from the Westone W4R, it does sound slightly harsh/sibilant to me in the treble at times, hopefully I can get used to it or figure out a way that works better for me.
I also dislike the thick nozzles and that they're not angled. When inserting deeply, the IEM angles out weirdly away from my head to where the cable doesn't really want to go over the ear but weirdly around and behind it:
Does anyone else have that issue? I can force it 'straight' and it's still fine but feels slightly weird coming from the W4R which i was able to insert deeper both due to the angles and the thinner nozzles.
As for the cable, there are a few suggestions in this thread, just search for 'cable' in the 'Search this thread...' box on the top right. From what I read so far, it seems like you can use 0.78mm connectors, but once you force them in, you can't go back to 0.75mm as the sockets will be stretched. There are also a few 0.75mm cable options.
Also, I read that the polarity of these sockets is different than most IEMs which further limits cable choice? My stock Westone W4R cable has the same polarity though so I'm not sure if that's true.
This is how my flc8s are cabled:
And my W4R are the same way. Is this uncommon for IEMs? If so, which one is switched here, L/G or R/G?
