IE200 are V-shaped too, but less exciting than IE300. I'm surprised already much warmer and darker IE300 was piercing to you while IE200 much more prone to that, at least tunning-wise is not. Did you compare them both using same tips and was it the stock ones? So far most IE200 reviews are a mixed bag while IE300 inception was mostly positive, which actually to many was and still is a great complimentory to IE900, some even prefers IE300 tuning to IE600/900. So far it doesn't seem IE200 have great chances to achive this status at least based on what I've gathered, including the neverending "sound cutting out" saga (there are already many reports on that matter from IE200 owners), as well as new problematic dual tunning feature in IE200.
Headfonia says IE200 is a downgrade to IE300 in most aspects.
Majorhifi describe IE200 treble as sibilant and too bright up top.
Super* prefers IE200/600 tuning without sayin much about IE300 technicalities, yet harsh things about IE200 technicalities.
WhatsNew says IE200 are unlistenable without EQ.
Damir Franc are not happy about IE200 either saying soundstage is a mess having intimate vocals and the rest of the sound disconnected outside of a thick dome, for him IE200 are oddly tunned compared to rest of the IE lineup (300/600/900) and he prefers cheaper 100 Pro's to IE200.
Sharur who like to judge headphones based on graphs thinks IE200 frequency response is terrible.
Bad Guy Good Audio says IE200 is not even close to IE600, what's more dosen't have technical ability to conquer ChiFi offerings in sub 150$ IE200 being mostly vocal centric lacking rumble in bass - something I very much enjoy with my IE300 and suspected IE200 are greatly lacking because of the tuning.
GizAudio posted two videos regarding IE200
first one very biased after brief test at the local shop hyping them as if they were baby IE600 for 1/4 the price. However in the
second video after having them for proper test he's much more reserved and less enthusiastic explaining new dual tuning gimmicky feature as potentially ruining the whole experience, and actually advising people not to buy IE200 at least not yet.
We can go on like this forever you pointing pros while I'm pointing cons and as you can see there are a lot of cons. Obviously I'm waiting for more reviews especially Joshua Velour's, Headphone Show (from two other guys than what was already published), Z-reviews to name a few bigger ones on YouTube. In a few months to come things will be clarified. However what baffles me the most some people calling IE200 an "upgrade" to IE300 for half the MSRP. Those who buy Sennheiser products since many years know this brand doesn't operate like that. What's next IE100 as an "upgrade" to IE600/900?
It's hillarious how things went crazy lately... maybe they made strategic decision product names doesn't mean anything anymore, but I suspect it's just the marketing department want to push IE200 sales like crazy to fight ChiFi. Well guess what IE300 was already doing that at the same price being multiple times reduced from 300$ to 150$ and even less.
