The IE200s are much better.
I agree that cheap IEMs today have made huge strides and that you don't need to spend crazy amounts to have great sound, but in the €300 - €20 range the differences are still very evident.
The IE200 with the vent-hole MOD (IE200 has dual tuning but with a sealing flaw) and Zero Red's wide-bore EARTIPS, sound almost identical to the IE600s (which is why it's not worth spending €600 on IE600).
As far as my tastes are concerned, IE200 is one of the best IEMs I've ever had and against all my expectations. The Salnotes Zero performs exactly like a €30 IEM...
The Salnotes give THE IMPRESSION of being detailed due to its highs (for me not very coherent and not very refined), but with many tracks that I know I realized that I am literally missing some points of the track itself and it creates a single mixture without definition with slightly crowded tracks, especially if there are instruments playing together but at very different volumes.
IE800 feels the weight of the years and if I have to spend crazy amounts of money, I switch directly to IE900, but both have a tuning far from Harman (for me this is an advantage)
