1 / 6MDAQS Overall — measured in the SoundGuys lab.
Copper is the most common — on 2% of the 48 in-ear monitors we've cataloged (of 39).
Wired-3.5mm is the most common — on 92% of the 39 in-ear monitors we've cataloged (of 39).
Silicone is the most common — on 64% of the 50 in-ear monitors we've cataloged (of 39).
False is the most common — on 66% of the 35 in-ear monitors we've cataloged (of 39).
The Truthear Hexa is an inexpensive, higher-quality IEM that should satisfy creators and music listeners alike. Wired IEMs have seen a lot of really awesome models released in the last 5 years, and the Truthear Hexa is a standout among the under-$100 crowd.

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.
