Yes, it is a fact that his is quite a bit larger and heavier than mine, however it is our hypothesis that since it is larger, it has more air volume, hence the variation in FR. We need to graph more customs (we will over the week hopefully) before we can come to any conclusion.

The size of a CIEM shell shouldn’t make a significant difference with “traditional” CIEM designs...meaning where all drivers are producing sound through tubes, however, the BC driver is really an uncertain variable I think. I‘m hesitant to get the MEST in a CIEM just due to my ear anatomy. That and the fact that the UIEM just sounds so spectacular to me.

Though through graphing both Crin and my customs (both Crin and Leneo graphed both), there is a rather significant variation in the FR, hence why we would like to graph more to test the theory.

Absolutely! I find that rather fascinating. I’m glad you guys are researching it more.

My Mest is shipped !!! I feel like a first time mother !!!!

So far, I find the treble on the UIEM sublime. Though there is a ton of treble detail, I don’t find it bright or harsh. I think I’m gonna stick with the UIEM, at least for a while. Interestingly, the CIEM measured and sounded quite different for Crinacle, though I have no idea how representative measurements with a BC driver are.

I'm personally intrigued by how you can one might capture and combine the result of the usual frequency response measurement with bone conduction drivers measurement. For one, I would assume that you need a vibration sensor with a good solid coupling with the shell. The usual vibration sensors are for low frequencies below 100Hz so maybe some kind of Piezo pickup is needed. And then, I think you would need to decouple the microphones from the shell/coupler/attachment so as not to pick up any vibration from the bone conduction driver. So the microphone needs to be suspended like a studio mic which is not typical with these measurement rigs. It seems like you need something very different... It's probably a topic for another thread but it makes me curious how UM figured this out.

On topic, I'm getting a kick out of this track. Incredible realism to the cymbals, snare, toms, bass, and the bite from the guitar with MEST.

I'm sorry if this has been asked before. Can I use QDC connector cable for MEST?

Yes. They fit perfectly.

Same 2 pin but not reversed polarity.

Same 2 pin but not reversed polarity.

So are QDC connectors reversed polarity, or are they normal? If buying a cable for Mest, should I select QDC or .78mm? Thanks for your time.

Qdc 2 pins are reversed polarity.

Qdc 2 pins are reversed polarity.

Thanks! I have always wondered about that. So, it is best to use QDC connectors wiring up the normal way (not reversed). Cheers.

Official qdc connectors are reversed polarity, whereas some IEMs have the same shape of connector, but the same polarity as tradition 2 pin connectors. FWIW, as long as I connect R and L sides the same, I have never had a polarity issue cause sound problems.

 

[Lokiiami]

Thanks as I find it very hard to search for this connector cable online as I'm not sure what term to use and seems QDC is the closest to it

Yes. They fit perfectly.

 

[colourgravity]

Yes! I have it, and your group are quite right
