Jumps to a B Tier with a 80 ohm adapter. Pretty wild.

Really dynamic. Bass can be a bit much in quantity sometimes (for me) and upper mids can be a bit intense (at that line where things could be shouty but never crosses into that territory). Good note weight and timbre. Stage is wide. Good details, and decent separation. For the price, I don't think you can go wrong with this! Previously Owned

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