Looking for recommendations.

I'm looking for a pair of iems sub 400 usd that doesn't require much eq or any if possible. Something with alot of bass preferable. These are some of the options I found while exploring this thread. The price kinda ranges because although I'm willing to spend a decent amount I don't want to pay for something twice as expensive for a small boost in quality. I'm pretty new to the iem world having just the simgot sm4s currently. They didn't have as much bass as I was expecting and they hurt the outside of my ear which I'm pretty sure is called the anti tragus. Not sure if changing the tip would help or if it's the shape of the actual monitor. Any advice would be greatly appreciated.
