Shozy Zero IEM Measurements

f**k yeah, a cheap IEM without DF midrange tuning. Now I need to hear these. The curves between these and the Andros from very low Z source look extremely similar. I'm sure that these will sound too bassy with not enough upper midrange for me based on these plots (I still really like the UERM tuning), but at that price it's hard to bitch.
D3 distortion bump in the mids does look concerning though, above what I consider to be audible. Still, most likely not as bad as any other BA driver IEM (including Andro) which just can't seem to handle very high volumes at all.
Treble rolloff doesn't look very bad in the plots and considering that it's a dynamic driver, I'm assuming that extension to 20kHz is no problem.
Of course you will be stuck with the warm tonal balance with these, unlike the Andromeda where you could use a device with higher OI to tweak the sound.

 

My measurement of Shozy Zero using MiniDSP UMIK-1 measurement microphone and DIY acoustic coupler, before and after burn-in. All channel measured at least 3 times (before and after burn-in) with 1/48 octave smoothing, and then averaged.
