I bought the MMK3 and I liked it but I didn't love the treble response/bass transients/coloration. I tried a lot of different tips/cables and a few sources which helped a bit, but I ended up buying the MMK2 and preferred it in the end.so what did you end up with?
I found the MMK3 treble a bit crispy sounding and felt it presented microdetails in a way that sounded forced.
The MMK2 has inferior bass, but it has a more neutral and balanced presentation both in tonality and tuning. It also has one of my favorite treble responses sitting alongside Anni 23 and the Helios OG. MMK2 has a classic tuning that should stand the test of time.
Objectively, MMK3 is a better IEM though, and these sentiments are reflected in my IEM rankings.
