I probably put it at S- or S.
If you are in the US and can get the KSC75 at around 20 usd, I dont think there is a bud that is better than it (non-DIY) in stage. Bass is easy to beat it in though.
But elsewhere, where the KSC75 is close to 40 usd…it is close to my own DIY buds price so…yeah…
Sounds like MX500 shells works the best for you then.
Also, FYI: I should be getting my DIY batch next week, so look forward to the “official launch” of RikuBuds. 
Out of curiosity. Are those drivers supposedly FR matched by the manufactured? If yes, how is the consistency of that? Or maybe - any difference between them is so minor in comparison to all the rest of unknown factors affecting the end FR (housing, filter composition etc) that it just does not matter and you need to pair them once assembled anyway?
I have no clue, I am assuming there isnt really any FR matching done by them, at most I can see them try to match the drivers in terms of impedance.

Hi, I know you tried several GS Audio IEMs, I searched and found references to the GD3C but if there were any impressions/review notes I must have missed them. I don’t know how long they’ve been available for but I noticed the GD3C and GD3D today and I wondered if you’ve listened to either? Thanks in advance!
I haven’t heard them. You can blame the CRA for that.

Oh, and if you didn’t notice, happy April fools.
It is absolutely NOT April fools for me yet and I definitely DID NOT fall for this … 
the second set looks like it gives you extra hp and mana
Hahaha, yeah lol. Also looks pretty edgy to me with the divider and connector.
These are some pretty sets, man 
I’m not into buds but jeeze, just the way these look tempt me
Why are buds not up your alley? Due to the zero isolation?
How have I not already heard Gangnamcut (Psy - Gangnam Style / Linkin Park - Papercut) at any time these past 9 years.
Well then.
