Large Spinfit CP145.

The CCA Hydro arrived. First impressions: very superior to the Kiwi Ears Quintet, which I don't like at all, at half the price. Inferior to the FH9, at 1/4,6 of the price. Inferior to the MP145, at roughly the same price. Roughly equivalent in quality to the ARTTI R1, but at three times the...

Sorry to be this way... But those edges, man. Did you use a chainsaw or something?

Hard to know without knowing the dBSPL for sure. If we asume 90, as in the other graph, it is probably not an issue in the slightest.

I have bought the CCA Hydro. I'm a junkie, man.

Supermix 4 is looking good.

Yes. This issue is 100% there. Not nearly as bad as with EW200, though; where the flex is so loud that you may think you are severely damaging the drivers and maybe your ears.

They are at 138€ over AliExpress right now. Practically a steal, given the quality of the set.

"Right" is kind of subjective. Many people seem enamored of the Mega5est. This seems to be going for something similar. I find the Mega5est interesting, but importing it to Europe seems to be not that easy without being murdered by customs.

That seems to be the case. More bass, less treble. Normalized to A4, Supermix 4 looks like a tilted EA1000.

SuperChonk just uploaded this:

I'm really interested in the Supermix 4. I'm going to buy either that or the Kiwi Ears Quintet. Supermix 4 seems to provide more bass and more treble extension. I'm really interested in seeing how they compare and what the final price is.

Maybe. I don't know how reliable Rtings is, but it aligns with my experience: https://www.rtings.com/headphones/learn/dynamic-vs-planar-magnetic Headphones.com also seem to argue for better extension both in treble and bass...

Due to individual variability, it is hard to think that there is a perfect IEM for everyone. But given how many different IEMs there are out there, there must be a "perfect" one for every of us. That is what we are trying to find when we buy a new set again, again and again.
