Too similar to the M3 to be worth the price markup.

Average Technical & Tuning Grades

Average Tunign Grade

B-
  • Expect a friendly tonal balance that could use polish but remains inviting. Great for casual listening, less so for purists.

Average Technical Grade

B
  • Technical ability is serviceable, keeping basic detail intact across simpler tracks. It keeps up with acoustic tracks without much fuss.
Bass C-
Bass stays subdued, content to hover in the background. It keeps things tidy, yet unremarkable.
Mids B-
The region sounds agreeable overall, delivering clarity without flashiness. Slight warmth keeps things easy-going.
Treble C
The top end sounds acceptable but lacks the smoothness of higher tiers. Air is hinted at more than delivered.
Soundstage A-
Immersion steps up dramatically as width, depth, and height integrate into a cohesive hologram. Everything sounds naturally spaced.
Details C+
Decent detail retrieval that handles most textures while leaving some micro-information understated. Most textures come through cleanly.
Imaging B+
Good imaging with precise instrument placement and clear front/back localization. Positions snap into place convincingly.
Gaming C
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical. Bad value-to-cost for gaming purpose - not recommended
