Comment: The only saving grace is the bearable tonality and bass for bassheads. Bass bloat with recessed, messy midrange

Abysmal fit and I couldn't actually listen to them without having to press them into my ears to seal. I'm sure they sound fine. YMMV.

Timbre benchmark. Fit is awful. Sounds a bit veiled and mids are below average for the price. Dethroned by Mele, even tho it has better timbre and treble extension. Remove the grill for better sound.

Blon BL03 Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C
  • The tuning lacks refinement, jumping between dull and shouty without settling. Vocals frequently sound off-kilter.

Average Technical Grade

C-
  • The tuning renders a cramped window into the music, with nuance fading fast. Expect grainy textures to creep in.
Bass C-
Expect a conservative bass profile that maintains order but little excitement. Basslines track along but rarely stand out.
Mids C-
It delivers a workable midrange that could benefit from smoother transitions. Timbre isn't quite convincing yet.
Treble D+
The upper range behaves inconsistently, blending dullness with sudden glare. You'll notice sharp spikes alongside dips.
Dynamics C-
It maintains a steady dynamic profile that neither offends nor inspires. Swells arrive but lack drama.
Soundstage C+
You start to perceive distinct rows of players even if the ceiling still feels low. Layering is present but still modest.
Details D+
It can follow the main lines but loses composure once arrangements become busy. Fine articulation is frequently glossed over.
Imaging D+
Modest imaging with basic left/right positioning that never quite nails the center image. Left/right cues exist but are rough.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

ROSESELSA Aurora Ultra Scorings

Average Technical & Tuning Grades

Average Tunign Grade

C+
  • A mostly enjoyable signature keeps things listenable despite a handful of quirks. It handles most playlists without major complaints.

Average Technical Grade

C+
  • An honest, middle-of-the-road performance preserves structure without chasing micro-detail. It's respectable for everyday listening sessions.
Mids C+
The mids are solid and dependable, though not especially remarkable. Vocals stay reasonably grounded in the mix.
Treble C+
Highs come through with reasonable clarity while staying mostly smooth. Sibilance is mostly controlled.
Dynamics B
The performance feels robust, with satisfying punch and natural transitions. Nuances are easy to follow.
Soundstage B
Lateral spread stretches comfortably while front/back cues start to feel convincing. You can trace front-to-back movement.
Gaming C+
Fundamental left/right positioning with limited depth perception. Works for non-competitive gaming but lacks precision.
