Fanmusic Hexa MDAQS
Multi-Dimensional Audio Quality Scores, Scale 1 - 5
Virtual mean opinion scores (MOS) on a 1–5 scale, modeled from the measured response by HEAD acoustics’ MDAQS (Multi-Dimensional Audio Quality Score) model. Higher is better across timbre, distortion, and immersiveness — add other models to see where this one lands.
The verdict
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.
✓Liked: Sound quality, Isolation, Ease of EQ, Durability
✕Could be better: Smaller ears won't fit, No microphone
