I guess we can use an adapter like this to turn straight into angled:

But the kind of adapters on the market are bulky and not slim/portable. If Fiio makes a better adapter (or include it with IEM cables), I will definitely buy it.
Another thing about IEM cable is that it has to be flexible. For reference, the Westone IEM cable is good enough.
And I want to know this too: does that Westone style cable (the 2nd one) contain metal memory wires that go around ears?
I actually hate those from my Westone cable, because the metal memory wires create noises by rubbing against my glasses. In my opinion, metal memory wires are not necessary (just add a cable cinch, which seems to be there on Fiio's cables already). Lots of people use VSonic GR07 IEMs without ear-guide, as its cable cinch does a good job in holding cables.
