The iem sub has a post with some recommendations at various price points. I’d probably start there, not sure your budget and I don’t know have the most experience with the super cheap ones: https://reddit.com/r/iems/comments/1la65kr/top_5_iems_in_eve...

I also encourage finding the right tips. Tips are cheap and finding proper fitting ones is important.

Not gp but I really like the sound of my GK Kuntens and 7Hz Zero2s. Both have a rather V-shaped sound signature, some like it and some don't. Though unfortunately the Zero2s feel a bit uncomfortable in my ears when using them for longer

Most of the ones that are over 50 can last a lot of time and have good enough sounds. But the most important stuff are the tips and the cable. Make sure the former fits (just buy a pack) and the latter is thick and braided. Some cheapo ones send every rubbing amplified to your ears.
