Merging an ear to a head higher detail to lower detail

Noobie who seems to have gotten themselves into a corner here. I’m trying to merge this ear to the head, but can’t figure out how to transition from the higher detail on the ear to the low detail of the head. as I understand it, if the basic topology is correct I can modify the shape afterward if needed. But I need to come up with a way to merge these without having to add a billion loop cuts preferably. Maybe I’m missing a solution or just have to accept the loop cuts? Any direction would be great, as I want to get this character done sometime soon.

Here is what I got.
