7Hz x Crinacle Zero:2 IEM Review

[MC_RME]

It's a pity @amirm doesn't do fun measurements like that - what is the maximum SPL or milliwatts that cause drastic rise in THD at 20 Hz. I don't have the equipment to do that. With normal headphones one can shove earplugs into the ear canal, then listen at lowered volume to the point where the drivers break up (old, but very efficient trick). With IEMs this obviously isn't possible.

Especially with the difference that I observed between Zero2 and Blue Zero 2 I would really like to see this verified as measurement.
