Average Technical & Tuning Grades

Average Tunign Grade

B+
  • Generally enjoyable tonal character with some noticeable unevenness. Maintains listenability while showing room for refinement in frequency balance.

Average Technical Grade

A-
  • Competent technical presentation. Handles separation and detail well in most tracks, with modest soundstage and acceptable imaging capabilities.
Bass B-
Average bass performance - present but unremarkable. Has reasonable texture but lacks depth and physicality.
Mids A-
Excellent midrange with natural timbre and great detail retrieval. Vocals are forward and emotive with lifelike instrument reproduction.
Treble A-
Excellent treble: airy, extended and well-controlled. Great micro-detail retrieval without sibilance or harshness.
Dynamics C+
Decent dynamic performance. Good macro-contrast but micro-dynamics could be more nuanced. Satisfactory impact.
Soundstage A-
Excellent spatial presentation - wide, deep and tall. Precise instrument placement with clear separation in all dimensions.
Details B+
Good resolution with clear articulation of nuances. Reveals recording nuances and maintains clarity in complex passages.
Imaging B
Good imaging with precise instrument placement. Clear localization within the soundstage including front/back positioning.
Gaming B+
Respectable environmental presentation favors atmosphere over precision. Detects obvious directional cues while conveying game world ambiance. Value-to-cost may not be optimal for gaming-focused users.

In true Westone fashion: the "downslope" signature at its worst.

Smooth and balanced with really great detail retrieval. Jack-of-all-trades. If you can swing $370 for this and aren't willing to go up to $530+ for something marginally better, then just buy this and don't look back. Previously Owned

Good neutral set. Airy and open staging but with forward vocals although lacking in extension. Great layering and details but not 3D and more flat. Vocals could also be more open, and feels "stuck".

Great tonal balance with technicalities to back it up. Probably the best treble balance you find up to its price point. Mid-bass won't be for everyone.
