I've got the IE 200 (which I got on sale for AU$180, instead of the usual AU$240), and have been using them for a while.
TLDR: with Comply foam tips, my custom EQ, and an aftermarket cable (which I haven't gotten yet), they're a 5/5 and I am very happy.
First my two previous earphones are the
Truthear x Crinacle Zero, and the discontinued Sennheiser M2 IEG / Momentum 2.0 In-Ear:

So here are my very (long) subjective review/thoughts.
5/5 Comfort
Comparing only the silicone tips, the IE 200 are way more comfortable than the other two: and I can even lie down on them! The Crinacle zero is simply too big, and the momentum pulls on the bottom of my ear.
The included silicon tips feal the same as the silicon tips of my other earphones, so nothing special. The included foam ones however where nicer, but felt like they were barely in (I.e. I need bigger tips). This isn't important though, as I already had some very comfortable Comply Tips (although I think the diameter is just a little much for my ear canals, of course the next size down is too small).
I had difficulty at first because I wasn't inserting them according to the manual (I was inserting them with the MMCX connector facing straight towards the from of my head, but according to the manual they should be angled roughly upwards 45°).
1/5 Sound (with Stock Silicon Tips)
They sounded horrible with the silicon tips (in both fully pushed onto the nozzle, and only half pushed on), I think I mustn't have been getting a proper seal (my ear holes are too wide and deep?). There was basically no bass, and way too much highs.
I don't care though, because I don't use silicon anyway (as they're not comfortable).
3/5 Sound (with Stock Foam Tips)
They sound ok with the stock foam, no real complaints except that female vocals weren't as smooth as the Harman-compliant Zero (but they are not as loud, which is good!).
4/5 Sound (With Comply Foam)
I used my old Comply Foam tips from the M2 IEG (specifically, Large Isolation Sennheiser / T167 ones with Tech Defender/Wax Guard). The nozzle of the M2 IEG is a bit thinner, so I need to put a little extra effort to get them on, but otherwise no problems. (I can only get them in the fully-inserter position, they wont stay in the half-inserted one).

With these on, the bass is wonderful, but the highs still have the problem I mentioned above.
In particular, they don't have the problems I had with the M2 IEG when using my foam: the bass doesn't feel like it's vigorously shaking the inside of my head, and I can eat without massively amplifying the sound of my jaw moving!
I'm tempted to get the Comply 200 series, which are the ones that apparently fit properly, and they have 3 different shapes.

Of course they're expensive (AU$44 for 3 pairs!), and I have 2 pairs of my M2 IEG ones that haven't deteriorated yet so I don't want to waste even more money than I already have (I literally just bought the AU$73 Crinacle Zero, just so I could know what the Harman curve sounded like!).
Also just randomly, I rotated the earphones with the MMCX connector facing downward, and they were still comfortable, but it was less basy and more high pitched (maybe some people will prefer this sound?).
5/5 Sound (With Comply Foam + EQ)
In the end, this is what really matters. It took me ages to find a good EQ. I first tried the ones shared on this thread, and Oratory1990's EQ profiles, but I didn't like any of them (I suspect they weren't designed for use with my foam tips, and only improve the sound with the silicon tips).
Now, what I did before when I had my M2 IEG EQ was play with the AutoEQ feature of my DACs (the Fiio Tiny & Melody), and put in every Sennheiser earphone I could find a frequency response measurement for. I know this sounds weird and isn't an accurate way of simulating earphones, but it gives me a lot of different sounding EQ profiles to test, which I can then use to work out what I need to do when making a custom one. Unfortunately this didn't produce good results for the IE 200 (it did for the M2 IEG).
So then I tried something I thought was stupid: EQ my earphones to match the EQ with my headphones. The reason I thought this was stupid is because the harman targets for In-Ear and Over-Ear are so different, I assumed that the ear must process sound differently when it's just in the canal vs. also goes through the pinnae.
Anyway, it worked great (although I didn't copy the EQ for the portion less than < 500Hz).
Here is the result:
Code:
Preamp: -3.0 dB
Filter 1: ON LSC Fc 500 Hz Gain 1.0 dB Q 0.5
Filter 2: ON PK Fc 1800 Hz Gain -7.5 dB Q 1.0
Filter 3: ON PK Fc 3700 Hz Gain 6.3 dB Q 1.0
Filter 4: ON PK Fc 7600 Hz Gain -6.7 dB Q 1.3
And here are some graphs explaining how I came up with the EQ for my HD 558 and transferred it to the IE 200:

As pure coincidence, the shape of my EQ is very similar to the one
@Sebby shared above, but I've moved the frequencies to the left (
@Sebby is in yellow):

Anway, with my EQ, they sound very similar to my headphones (i.e. amazing!), they still aren't as "open" sounding: the sound is sharper and feels closer to my head. This is probably unavoidable as my Headphones are loose-fitting over-ear open-back ones, so the drivers are much further from my eardrum than on an in-ear earphone.
2/5 Cable [Skip this section if you don't like rants]
It works, is replaceable, is non-microphonic, is an appropriate thickness, and doesn't disconnect easily. Those are the only nice things I have to say here. It still has an advantage over my M2 IEG cable, as that was not replaceable, and moving/touching it would make loud sounds (but that was probably the sound of the earphones themselves moving, which is then amplified by my foam).
The bad things about the cable:
- It is ugly
- The colour doesn't match the earphones
- The chin slider/cinch/zipper is literally just a piece of cheap transparent plastic
- The plastic sleave bits at the earphone end of the cable are very stiff: you're supposed to bend these behind your ear to secure them, hide the cable, and stop the cable from tugging on the earphones. However, my comply foam tips don't feel good when I move the earphones after inserting them (as they expand to fill the canal), so I have to make sure I bend this plastic bit. Also, due to stupidity, I keep playing with the cable when not wearing them and then bending them into a different position (hopefully the novelty will wear off and I'll stop doing this). In contrast, the Zero cable has some kind of magic plastic spring thing: a little force can move them around, but when you let go, they spring back into their standard position.
- There are no buttons or micrphone. Although I rarely used the microphone on my M2 IEG, I used the buttons very frequently as I like to use them with my phone in my pocket, and if someone's trying to talk to me I can easily pause the music, or skip a track I don't feel like listening to, or alter the volume etc.
- My M2 IEG cable had a much slimmer and nicer looking connector:
Naturally, I then spent ages looking for a new cable. I wanted the following features:
- 3.5mm plug (so I can plug it into my Fiio Tiny which I use on my phone)
- play/pause button (these always comes attached to a microphone)
- volume buttons (some microphones only have the play/pause button on them)
- microphone (for occasional use when answering the phone)
- fabric cable (they feel nice)
- all black
- thin cable
- looks nice
- L-shapped plug (these are more compact and less anoying when used on my Fiio Tiny and phone)
- small plug
- non-microphonic (I just have to get lucky here, as you can't tell from a picture)
- MMCX connector fits perfectly (The IE 200 has a slightly non-standard socket sadly, and I couldn't find any cables that looked identical from the pictures)
- springy slaeve at the earphone end of the cable (i.e. like the Zero cable). I have no idea how to tell from pictures if it's nice and springy or horribly stiff, so I'm just hopping here.
Of course it's impossible to find a cable with all these features! And some I won't know untill I get it and try.
NICEHCK makes some nice ones, but they all have issues.
For example, the
BlackDawn has a nice cable, but I don't like the silver metal bits and there is no microphone/buttons:
View attachment 511054
The
MeetEva has a slightly less nice cable, but very nice metal bits but is still missing a microphone:
View attachment 511056
The
BlackWheat has a microphone, and still looks nice (but the cable material won't feel as nice), but it's missing a cinch slider:
View attachment 511057
So I gave up on them and bought this one from
AliExpress for AU$22.60 (but with a 3.5mm connection and microphone):
View attachment 511059
The microphone should hopefully look like this but black:

Unfortunately, despite the cable saying it is for the IE200/300/600/900, the connectors apparently stick out and come loose easily:
View attachment 511061
So I'm thinking of duct taping them on or something like that. (It's better than them not going in at all, which can happen as the IE 200 MMCX socket is recessed). Alternatively, I could get one with a standard MCCX connection and a AU$17 pair of adapters, but that just seems like a waste of money:

If anyone has any suggestions for a better cable, or some way to improve such a cable, let me know!
4/5 Overall
They would get 5/5 if only they had:
- Not included a stupid cable
- Come with foam tips that fit my ears properly! (this is probably not Sennheiser's fault, we all have different ears..)
- Not needed EQ to feel "immersive" (it would be great if Sennheiser made earphones to match the sound of their headphones, but considering they've discontinued my HD 558 the kind of sound I like is just not popular).
Oh and they look great (I like black), but I wish they didn't have the red ring to identify the right earphone, but instead had little braille dots like my M2 IEG.
Honestly, I expected them to be this good when I bought them, so I'm very happy
