CCA HM20 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

D
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

E-
  • Everything sounds flat and suffocated, with even elementary passages losing definition and energy. Expect little in the way of micro-details.
Mids C-
The mids sound serviceable but rough around the edges, needing polish. Occasional glare can creep into upper mids.
Treble E-
The top end feels muffled, with air and shimmer barely audible. Ambient reverb tails are chopped short.
Dynamics D
Volume shifts feel constrained, so build-ups plateau before releasing. Build-ups plateau before resolving.
Soundstage C+
Decent spatial presentation with noticeable width and a modest step forward in depth perception. There's a mild sense of width to enjoy.
Gaming E
Compromised imaging significantly impacts gameplay awareness. Directional cues often lack accuracy or consistency.
