Heavys H1E 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 Heavys H1E earbuds sound good with Hellblocker (ANC) turned off, offering a tuning that becomes genuinely enjoyable with a few small EQ tweaks, enough to satisfy this metalhead. That said, once Hellblocker is enabled, the sound shifts in a way that introduces clear trade-offs, making the differences between modes impossible to ignore. That lack of consistency keeps the Heavys H1E from feeling like true everyday earbuds.
✓Liked: Sound quality with "Hellblocker" off, Codec support, IPX5, Silicone and memory foam eartip options
✕Could be better: "Hellblocker" ANC changes tuning, Limited app functionality
