The "REAL" price is really fascinating. Last week the price was $209 and now with a 30% discount it is $229

Wow, several months later they replied. Looks like the YY BK2 uses a plain PET diaphragm. Interesting.

Also I moved the yincrow RW-9 up in my list, they're all good. I'm noticing some midbass on the NSC clear that seems to be absent from the RW-9, leading to better low-end presentation on the RW-9, though I enjoy the accentuated mids/treble on the NSC clear. It really comes down to preference.

Tl;dr
X6 for bassheads, plain warm with well executed bass boost. Overall resolution is just average.

RW-9 is similar to X6 with a little less bass and a little more upper mids/treble. Slightly better resolution.

NSC Clear has less bass than RW-9 but mids are more prominent. Might have too much midbass; the bass on the RW-9 seems better controlled. About the same resolution as the RW-9. It also sounds more airy, probably a spike somewhere 10khz-20khz range. Neutral with a little warmth.

All three have similar soundstage.

I still think the BK2 is the best choice for anyone who wants a clean neutral signature, though it has no warmth to its bass, so definitely not for bassheads, and it also has a smaller soundstage. But it has the best resolution and timbre imo.

If I had to recommend anything it'd be the RW-9 and BK2. At higher prices, you're going to get much better fidelity in IEMs.

Also found this old comparison of the X6 and RW-9 posted by Sam L, figure I'd repost it, seems accurate to my ears.

Usual Aliexpress tricks. I've noticed before a big sale, they suddenly jack up the price by 50% or more, then they put a "50% discount" for the actual sale, so it evens out LOL. Some new folks to the hobby will see 50% discount and pull the trigger unwittingly.

There's a shop selling the Tingo TC200 drivers - 5 pairs for $8. Don't know if they're just riding on the hype on these but they are a well known and reliable shop... link

Spoiler: TC200 Driver

Looks quite similar to me.

Yup. The glue is the only difference that I noticed but be sure to check the specs

Price is not the answer here but rather the effect of impedance. Many believe the Black-Gold 150Ω requires an amp to sound its best. So if you are planning to use it from a mobile source like a smartphone or a weak DAP then we would recommend the 40Ω model instead. The following are some nice comparisons between the models posted by our resident expert (god-tier level earbud authority) known as @ClieOS

Thanks for the input and quote from ClieOS. Really appreciated

There's a full comparison between the gold and silver somewhere in this thread, though I can't find the actual post right now. From what I remember reading, the black gold is warmer but requires a amp to reach full potential.

I do own the Smabat ST-10s black/gold and comes close to your criteria for sound signature. However, it is slightly rolled off in the treble and it definitely has a warm tilt. I can't speak for if its comparable to your ER2XR. Though I will say it was good enough to not have me reaching for my ER4XR and HD650.

I'm sold when you say ST-10s make you not reaching for the ER4XR, that also one of my favorite IEM.

Just ordered the Black/Gold version from Aliexpress for 97$. I don't know it's good deal or not but the price is acceptable.

Thanks again for all the advice

Its a different sound for sure but still fun to listen to in its own way. If I had to come up with a comparison, I'd probably say similar to HD650s with better quality bass. You can even get decent treble extension if you opt for donut foams but it does get a sibilant at time.

Thats a great price! I paid $149 shipped on Penon Audio a month ago. Hope you get them soon!

Well, it should be great for the price and having HD650 sound signature.

This is just one example (of many) of the helpful camaraderie and friendliness of our group and why we have the most "bad a@$!" thread on Head-Fi. I really appreciate and am sincerely thankful of that as it makes my day, everyday to visit the thread. Cheers and respects to all.

Thanks a lot!!! My favorite store too! It comes out to $128.44 CAD, which is the best price I've seen for them. They would be my most expensive buds, but I've been lusting after them for a while (I have their ancestors, the Svara L 32 omh which I love), so now might be time (re-reading those quotes from ClieOS are not helping lol).

Anyway, done! I think I deserve them

They will indeed sound awesome off of my desktop amp. And hopefully they will sound okay off of my bluetooth receiver (BTRK3 balanced). Someday I hope to also get the Qudelix 5K which will hopefully push them nicely.
