Kato is definitely not in your face, and I would not recommend them for hiphop since everything will sound light and not impactful; the etymotic series also aren’t recommended for hiphop since they lack low end. Timeless has good bass, but it doesn’t rumble and can sound thin and harsh at louder volumes.
I’d recommend the Tanchjim Hana 2021, especially with additional filter applied (comes with). Deep, rumbly bass, in-your-face, and great bass texture and thick notes. I listen to artists like Kanye, Kendrick, Fivio, Brockhampton, Tyler, and they sound awesome on it (~$180 wait for sale). Hana has the most, and best bass graphed, and in actual listening. You can get even more bass on the Hana with additional filters that it comes with (also great technicalities).
Also, IEMs with wide staging (left and right) tend to reproduce sound closure to the listener, and IEMs with stage depth (wall of sound away in-front of you ex. Timeless & Kato) are what you’re trying to avoid since there’s more air and everything is pushed further out.
