I've dabbled with external microphones, and they work "too well" if that makes sense!I recently bought a A56 phone and it works well with Merlin. I had used Merlin previously on a very old OnePlus phone and I haven't seen any significant differences between the two. Merlin can throw up some surprises however and there are some species that it has problems with, it has problems with really loud Great Reed Warblers, and surprisingly needs to be quite near calling Cuckoos that I can hear easily from far away. Sometimes it does invent unlikely species in regions or biotopes where they are most unlikely. I have never used a separate microphone nor would I bother...

There isn't much point having the app pick up every bird in a ridiculously large radius, without even a clue as to which direction they are in. So if the phone works on its own, I'd go for that now.
Unless you are doing something specific almost akin to vismig, where the extra detection range might be useful .
Having the merlin app send notifications to my smart watch is a lot of fun. You find something, then merlin confirms it on your watch a couple of seconds later!
