Where to go after first IEM?

Purchased the 7Hz x Crinacle Zero 2 as a first IEM and loved them. Paired it with the Dunu S&S and it changed how much I enjoyed audio. Across the board the Zero 2 was pretty neutral for me. It was good all-around but I found the sound signature a little too boring for me after a couple months of use and started looking for something different. As the title implies, I’m now looking for an IEM with a bit more fun to it, with more punchy bass and clearer vocals as those are the parts I found missing in my Zero 2s. Thanks in advance.
