I believe they get these measurements from measuring the driver inside a coupler sealed with an adapter like these.
Then they get the graph as well.

Damn,
Pinning it down in my keep-notes. Hope for the best, long time has passed since we listened to a market breaker.
How would you describe the sound?
I love it bro, primary attractions for me would be Sub-Bass, Soundstage Depth, and natural timbre. Sorry for my late reply haha.

The Pula PA02 showed up today, a day early. Iāll save the more technical stuff for the PA02 thread, but first impressions are very positive. This is the first set of IEMs of this type I have ever had. The whole IEM experience so far has been very different and eye-opening for sure. Iām having a lot of fun with it.
As for the PA02s, Iām lovin them right out of the box. Of course, I have nothing else except the Penta P50 to compare anything to, but to my ear these are pretty damned good! The shells are beautiful, much nicer in person than the photo. They fit into my ear very well and once I get them settled, they are comfortable. Unbelievably, the silicon ear tips that were pre-fitted are doing great, so I got to actually listen to them right away. And the cable is really nice. I wish it was a little longer, but that is a minor issue. Iāll most likely get a replacement cable like I did the Penta. The PA02 uses the 2 pin connector, whereas the Penta uses the MMCX. From a first impression perspective, I prefer the MMCX, but the 2 pin is working fine.
So now itās time to get some time on them and see how it goes. We are off to a very, very good start. The first thing that strikes me is how musical they are. The SH-9 is really driving these IEMs well, also. There is great synergy happening between it and the PA02.

Not annoyed bro just it seemed a bit rude thatās all, no please or thank you seeing as youāre asking your fellow community members for their opinions to help you 
I just wanted a quick comparison.
Apart from that, I couldnāt thank you because no one could answer.

Another upcoming model, like Cantor, that has a telescope, er, rectal probe, er, REALLY long nozzle.
Ouch. If I wanted an Etymotic, Iād buy one.
looks cool but Iāve always been a tribrid guy, I do love ESTs though but they always end up expensive as hell lmao

Wow, thatās some news! Iām curious if the tuning will change with the added EST. Itās probably going to be expensive. I think an extra dynamic driver wouldāve been more useful, but oh well! Thanks for sharing!
