The CI30120 seems much less peaky than the CI22955.

Very much appreciated! Thank you for doing this. May I ask what iem is it from?
Also I know you probably soldered the pads correctly, but I found out that if the CI pads are not soldered covering the hole they got under, they act kinda similarly to the FR you posted.

It's from very popular 10BA
Do you mean the red or green plot? If you don't cover coil pads fully you essentially create a venting, but I think this wasn't the case here.

Red plot. Yes, that's what I meant.
It's from very popular 10BA Chinese company Flagship

Would you provide your comments on the sound of the unnamed flagship?

I can for universal fit version cause I haven't listened to the custom unit. They use slightly different drivers and different filtering. from memory they were pretty rich, full bodied sounding IEMs, good extension on both ends. It's like a W shaped signature, overall it's ok sounding IEM if you like thick notes but at the same time some edge on higher frequencies.
Different drivers for universals and customs? That's the first one I've heard like this :O
Thanks for your impressions though!

Yup the universal has normal 22955 CIs

Interesting...were their frequency response the same?

Did you volume match?I had an interesting experience when testing my new IEMs. I made them with the new UE style connectors. I first tested them using my original UERM cable and then I tried them with a mic cable I bought off Lunarcables. Last I tested them with a copper upgrade cable.
Assuming the copper cable is the normal frequency response, the UE cable resulted in a 2db frequency response dip from 3kHz up to 6db dip at 6kHz. The mic cable also resulted in a dip but was half that of the UE cable.
Listening tests afterwards also proves the testing correct.
Anyone else experienced this?
Did you volume match?
Yes - my sound card for testing this has no volume control I think it is due to the cable resistance is slightly larger

Sorry I'm not an expert on the subject. How to correctly adjust the volume in the frequency test? Set to 0 dB in direct connection from vol out to mic in in sound card? (blue line)

I see what you mean. Unfortunately I can't volume match them. The sound card was made purely for measurement purposes and doesn't have a volume control. Though through listening tests I can confirm that the sound gets much worse no matter what volume I put it at.
