I've actually been wondering whether maybe there has been a great deal of inconsistency in sound quality with the Frogbeats products (namely the C4).
Some very respected reviewers (one is even a mastering engineer of many years) absolutely loved it, and thought of it as clean and transparent with impressive extension in both the high and low end.
Other reviews say almost the complete opposite. Either everyone is having a SEVERELY different subjective experience... OR each C4 is not identical to the next.
Perhaps the custom moulding process isn't perfect? Perhaps quality control isn't so great with this "startup company"?
Either way, it makes the purchase way too risky for me, especially as a critical listening/reference CIEM.
It's a real shame though, because if it's just a matter of quality control, there's a chance I would get a superior product to the UERM. But also a chance I'll be sorely disappointed.
I haven't looked into the UE Miracle! I will do some reading about it.
I don't know man, I'd say they should be pretty consistent. I mean, the drivers should be pretty much identical in sound. The only thing that's left is the distance between the drivers and the tip of the bores I guess. I don't think there should be That big of a difference between models! Only if there is something wrong with the drivers :0
I should be getting a 4 driver model from cosmic ears next week, cheap but very neutral ciems.
