Super* Review 6* * score normalized
Harman target tuned. Sounds pretty V and contrasty. Not a whole lot of mids. Fairly tasteful. Good sense of separation. Sterile/Lifeless mids and annoying treble. Needs foam eartips.

B+ Tuning
B+ Tech
Fun sub-woofer sound in the low-end, nice bouncy textue, but uppermids/treble can be too bright, especially with 15K treble peak. Basically a more v-shaped version of the OG TE Zeros. Vocals can be a bit shouty and thin.

Average Technical & Tuning Grades

Average Tunign Grade

C
  • Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.

Average Technical Grade

C+
  • Satisfactory technical performance. Handles basic detail retrieval adequately in most tracks. Maintains reasonable cohesion in simpler arrangements.
Mids C+
Decent midrange performance - balanced but unremarkable. Adequate clarity for most genres without notable flaws.
Treble C+
Decent treble with acceptable extension and detail. Can sound slightly unrefined but avoids being harsh or sibilant.

Limited dynamic range with poor micro-detail. Subtle volume changes are lost, and transients lack proper attack.

Decent spatial presentation with noticeable width. Some depth perception but height dimension remains underdeveloped.
Gaming C
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.
