Are these the bass version of the Yincrow 2000 ? Will be waiting on your sound notes.
Bass version?
As far as I know, there is only one version of the RW-2000.
You might be thinking of the RW-1000 which does have a bass version.

I guess all of these posts are the aftermath of Aliexpress sales and a prepared debit card 
Hope you will find some gems you enjoy…
hahaha, yeah. Everything literally came at once. I will take my time with them though so no more impressions coming today (and especially since my school work is taking most of my time now…).

Yeah, I should probably get back to school work too…
A lot of missed lectures recently, the quarantine starts to hit pretty hard (in hands with laziness and procrastination)

It indeed is the biggest box out of the packages I got today.
Sry, another day for that.

YUIN G2A impressions:
Bass is very clean and is very tight and fast, but it’s because the quantity is extremely low. Lacks quite a lot of texture. Rumble is pretty much non-existent and extension is horrible.
Mids are…actually somewhat recessed. But quality is very good, especially with the female vocals. Although male vocals lack quite a lot of warmth and is too thin.
Treble is very good because of the airiness and the detail is very good.
Technicalities are very good as well with the most notable being the soundstage and the airy treble is a big factor here. Tonality is leaning towards brightness and is bass-rolled V-shaped.
Compared with the KSC75 (parts express headband), the mids and treble are better on the G2A due to them being more detailed and resolution is better, although the mids aren’t recessed on the KSC75. BUT the bass is a lot better on the KSC75 for my library. It is simply lacking too much on the G2A.
The comfort however isn’t really good for me, the pads make my ears itch more than the KSC75 and the ear clips are made out of hard plastic and doesn’t offer you much flexibility and adjustability.
Which made me pull out the ear clips from the KSC75 and fortunately they actually fit the G2A and made it a bit more comfortable. This did change the sound, the mids aren’t recessed any longer and I believe it is because the stock clips made me get a bad fit. So, tonality is just bass-rolled bright-neutral, instead of having the characteristics of a V-shaped sound (recessed mids).
Yincrow RW-2000 impressions:
Bass is very clean and is fun at the same time due to the boost. Speed, tightness and texture are top tier.
Mids are excellent with very good tonality for both male and female vocals and clarity/detail are very good despite the high bass quantity.
Treble is airy as most buds are and treble extension is good as well, very non-fatiguing but detailed treble.
Technicalities are very good but most notable is the huge soundstage and that the timbre is excellent as most buds.
Comparison with the Yincrow X6:
The sub-bass is lower on the RW-2000 and doesn’t rumble as much either. Extension is similar. But otherwise, the speed, tightness and texture are better on the RW-2000 while the overall bass is very similar.
Mids and treble are a lot better on the RW-2000 and the tonality is brighter than the warm X6 and is more neutral than the X6.
Technicalities and overall resolution are leagues ahead on the RW-2000.
This might be my favorite bud and worthy of being called a TOTL bud.

Ikko OH10 impressions:
Why didn’t I get this when it was first released???
Bass is very well textured and has a lot of quantity, pretty close to basshead quantity BUT it is very tight and clean so it doesn’t muddy up the rest of the sound like usual basshead quantity of bass would do.
Mids are a bit recessed but tonality and timbre are excellent. And detail is good as well despite the huge bass.
Treble is quite airy and sounds very natural as well without being shouty.
Mids and treble are very similar to the Sony XBA-N3 in timbre and coherency. Very impressive.
The bass on this is actually the most similar iem I have to the Dunu Zen bass. So, if you want to experience the Zen bass (which is my nr 1 iem in bass) then the OH10 is a budget way to do that. (it definitely doesn’t have as much texture as the Zen, but compensates with more quantity and the tightness and speed are very similar.) It also reminds me of the Dunu EST112 bass.
I know there are some people that have asked me what iem to upgrade to from the OH10 and I am honestly not sure (yet) after hearing it lol.

@luizgarcia Check the post above lol.
Will need more time to analyze it more but I can at least confirm that the LZ A6 is completely different, so not sure if you will like it. It does have a faster, tighter and more textured bass, but it doesnt have as much quantity (even if the graph might tell you that lol).
I think the Dunu EST112 or the Zen might be the ones to get if you want a bass similar but an upgrade in quality (Oh10 has more quantity though). Will add the OH10 into my EST112 review though so just be patient for it.

I think I may have compensated for the low mids being recessed by a little extra volume which can make the gain sneak up there lol. But Yepp it was/still kinda is my bass test IEM and was my first big boy IEM so its been hard to find an upgrade to it LOL. The OH10 is a beast

What tips are you using on it? I found that the Elecom EHP-CAP20 suits it better than the Final Type E and also the Radius deep mount.
Well funny you ask, when I was using it last I was using spiral dot tips, the og. I think the elecom are the upgrade if I remember correctly right?
I consider the radius tips the upgrade to the wide bores like the jvc/azla.
The elecom is its own kind of tips lol.

Ahhh derp, yea final tips are good and same with Xelastec, but with the best seal the sub bass made me nautious, so either I was sick or the titanium driver is just that good LMAO. The spirals worked great for lessebing the seal and for a comfy fit for the shallow stem etc.
