IEM for beginner.

Hi! I would love to experience music through IEMs but I'm a bit confused about which model to choose, as there are so many options available..As a beginner, I'm looking for a model that is not too expensive yet offers good quality, particularly in terms of bass and overall sound quality. Currently, I use AirPods Pro and Sennheiser Momentum 4. I hope you can help me choose the right IEM..
