IEM for soundstage (I’m a beginner)

Trying to step into IEM since headphones aren’t really that comfortable for gaming for long hour sessions. So a little about myself I own and tried many high end headphones from Utopia to Elite to Z1R etc..and so far I think I care mostly if sound is more vast with great size of soundstage. Intimate headphones even with high resolution are very good but fatiguing so I tend to care about soundstage more. So the HD800S and the Elite have really wide and nice soundstage while the Utopia has narrow soundstage yet open which is also good.

So now I’m really interested in IEM since I think they’re so good and comfortable for gaming. I want them to have solid bass clear mids and balanced treble. Overall balanced sound signature with emphasis on bass and of course soundstage. I don’t mind slightly warm neither as long as it has soundstage. What do you recommend for those sound qualities. Which IEM would you say have the most soundstage much like the Hd800s
