1 / 9MDAQS Overall — measured in the SoundGuys lab.
Alloy is the most common — on 2% of the 48 in-ear monitors we've cataloged (of 39).
True appears on 34% of the 35 in-ear monitors we've cataloged (of 39).
If you like earbuds, but you're looking to grab a decent set of wired in-ear monitors: the KZ ZS10 Pro aren't a bad buy by any means. Though the space has gotten crowded in the last five years, these earbuds are still pretty decent for what they do.

Measured frequency response (dB) against the SoundGuys house target — the dashed curve. The closer the measured line tracks the target, the more neutral the tuning; peaks ride above the target, dips fall below it.
