Comment: Treble tuning is one of the best up to $200 range. Neutral bright decently tuned, decent soundstage, surprising treble tuning Limp bass with zero texture, might be too bright for some

Budget tech king due to neutral bright tuning. Needs and loves power. My favourite sub-50 set so far. Might come out as shouty/hot. Responds well to EQ and Moding. Beaten by CRA(bassy) and Titan S for my library.

Bone conduction on the cheap. Buzzy, springy tonalty that makes for fun bass, but carries a little too much tonal affectation. Like a baby Kinera Plutus Beast

Average Technical & Tuning Grades

Average Tunign Grade

D+
  • Tonality remains inconsistent, with uneven peaks and dips that disrupt musical flow. You'll constantly notice peaks or dips pulling focus.

Average Technical Grade

C-
  • Even moderate complexity exposes the limited resolution and narrow sense of space. Technical fans will find it lacking.
Bass D
The bass sits quietly in the background, providing only faint support. Live recordings lose their stage thump.
Mids D+
Midrange is highly uneven, veering between shouty peaks and hollow dips. Tonality swings between shouty and withdrawn.
Treble D+
Highs feel erratic, with dips and spikes that make the signature unpredictable. It alternates between splashy and dull.
Dynamics D
Volume shifts feel constrained, so build-ups plateau before releasing. Build-ups plateau before resolving.
Soundstage B-
Decent spatial presentation with noticeable width and a modest step forward in depth perception. There's a mild sense of width to enjoy.
Details C-
Average resolution that reveals the basics while missing many of the subtleties. It reveals enough to stay engaging.
Imaging C-
Center information lands in the right area but not with laser focus. Separation is adequate for casual listening.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

  • It sounds pleasant overall, with some uneven spots that hint at room for refinement. Vocals remain pleasant despite the imperfections.

Average Technical Grade

  • An honest, middle-of-the-road performance preserves structure without chasing micro-detail. It's respectable for everyday listening sessions.
Mids C+
The region sounds agreeable overall, delivering clarity without flashiness. Slight warmth keeps things easy-going.
Treble C-
Treble is adequate overall, though its texture can feel coarse. Longer sessions may expose grain.
Dynamics B
You get confident dynamics that track both macro swings and rhythmic drive. There's life in every crescendo.
Soundstage B
The presentation supplies a believable venue outline where each instrument owns its pocket of space. The stage opens up nicely for live cuts.
Gaming B
Decent spatial awareness for fundamental positioning. Creates satisfying atmosphere in story-driven games while handling basic directional cues.
