I think it might be easier to use the mx500 shells to show tuning variety as that is where you get the widest representation within the ultra budget sector and the lack of options in the other shells means all the buds in the pack would lean on the warm side as @Rikudou_Goku pointed out.

Qian/ Monk Kite/ RG39
Mx500 Dark
Mx500 Bright
Mx500 Neutral
(not many bassy Mx500 at that price range otherwise that could be a category)
Yes true, if all you want is to try different tonalities then mx500 will be the most common and easiest way.
Does Ks DBX sound noticeably different/ better than Ks DB1?
It’s hard to understand, but they are in different categories in his guide. I weighted DBs at 3.3g each earbud.
But DBX says Damascus, whether it’s real or lasered, maybe shell material is the key difference? Anybody can weight the DBX to compare?
It’s this the only guide that we have? I could’ve sworn that I saw another with price tiers. Which I know this one has it’s price rankings as well, I just couldn’t sworn I’ve saw another.
And anyone have any info on the yinman 150ohm? I only know of one person that had it(quark) and he sold them right away. They’re on sale right now but having someone immediately sell them after they received them makes me uneasy about them
The DBX does sound a bit more refined compared to the DB1, with a smoother and more detailed tuning. The Damascus shell might not drastically change the sound, but it can affect how it feels and resonates. If you’re after a premium feel, the DBX might be worth it.
The Yinman 150ohm, I’ve heard mixed things about. The fact that Quark sold them quickly could be a red flag, but sometimes it’s just about personal preference. If they’re on sale, it might be worth a shot if you’re curious, but maybe check if there are any more reviews out there before jumping in!
Thank you for the info. I’ll definitely search for more reviews first.
For any recommendations for sub $50 buds? I’ve been eyeing the DX7 for the longest time, but don’t want to spend $100 just yet. I guess with 11.11 coming I should just keep browsing AliExpress. Maybe I’ll get the Dunu Alpha for a steal.
You’re welcome! For sub-$50 buds, the Dunu Alpha could be a great pick, especially if you can snag a deal during 11.11. I’ve also heard good things about the Qianyun Qian39 if you’re into a more balanced sound. Definitely worth keeping an eye on those AliExpress deals!
This seller (me) has a barely used Dunu Alpha 3 for sale, and other great earbud deals. 
Thank you. I forgot about the Qian39. I’ve never tried a shell like that and I’ve read that they’re pretty good. Maybe I can get the Dunu and the Qian39 at the same time at a discount.
I’ll most definitely be watching those sales. Thanks
I didn’t even see your post at first. Sorry about that. I’m gonna check out your classified. Thanks 
Edit: Unfortunately it’s a no go for me. 
I don’t have anything to run 4.4mm on. But that’s a great price for the 3. I have the last 2. Somebody should snag up with a quickness.
What library/genres do you have? Cuz those 2 are pretty damn different.
I’m mainly a jazz listener. Like 95%. The other five would be a sprinkle of classical and classic rock. But I have jazz pumping and into my ears most of the time
You want something a bit on the warmer side then. That qian39 should be doable but that Dunu is pretty bright. At that price range you are in my Gen 1 area, Rider 1 is my rec.
I was looking at your site again and saw the gen 1 and their prices. Let me think about it for a minute. I’d like to keep it at $50 or under. And with shipping it’s gonna put me over that.
I’ve always wanted a pair from you though. Thanks for the recommendation. It sounds like something I would love actually. I’ll let you know if I can swing it or not. I may have to save a bit more.
Need to add:
My time with the Penon Conductor has been my most positive earbud experience to date

Flathead Society’s Earbuds Ranking List
Version 24112024
README
We’ve prepared this post to collate all the wonderful knowledge and information on earbuds that exist on various forums and websites. The recommendation list is, like all audiophile ranking list, subjective, albeit we have tried to make it less so by only including earbuds that are reputable, as in, reviewed by multiple trusted earbud lovers.
We will try to keep this list as updated as possible. Our aim is not to reproduce an earbud release timeline like Woodyluvr’s famous document - rather, we want to make a one-stop shop for newcomers and veterans alike who are considering a new purchase.
Hope you find the info below useful! Note: within each category, the earbuds are listed in alphabetical order and do not reflect any prioritisation.
