I also have way too many IEMs… and I keep buying more, hoping to discover some magic tuning graal (hasn’t happened, so I now try to limit myself to sub-$100 IEMsI'm a junkie of buying IEMs, I have spent thousands of euros in the last two years.
Maybe 5128 doesn't work as well for the rest, I concede that. But after seeing what a HE400SE and an EW200 can do with EQ when I have things that are 30, 40 times more expensive, I cannot rationalize the logic of my constant expense on new gear.
Beyond reasonably quality drivers with no evident distorsion, tuning seems to account for almost everything. And you can achieve a lot with tuning on your own if you have good data.
My only issue is that 711 clone measurements over Squig don't seem to work for me at all. Maybe for some people 5128 measurements are also like that. But it is really worth the try, in my opinion.
I wish some OEM would be honest enough to publish a monthly PEQ profile to experience with their entry/mid-level IEMs, with some explanations as what it may achieve.
That’ll be a refreshing approach instead of constantly pushing new models—like KZ/CCA every other week new entry.
