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. Previously Owned

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.

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

D+
  • Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.
Bass C-
Subdued bass response that stays mostly in the background. Lacks energy and impact but maintains basic definition.
Mids C-
Midrange is passable but unrefined. Lacks detail and smoothness, with occasional harshness in upper mids.
Treble D+
Uneven treble response with noticeable peaks and dips. Can sound both dull and occasionally harsh simultaneously.
Dynamics C-
Average dynamics - passable but unexciting. Transients are rounded and micro-dynamics lack refinement.
Soundstage C+
Decent spatial presentation with noticeable width. Some depth perception but height dimension remains underdeveloped.
Details D+
Modest detail presentation with significant loss of texture. Nuances are masked and complex passages become congested.
Imaging D+
Modest imaging with basic left/right positioning. Lacks precision for center placement and suffers from positional blurring.
Gaming C-
Minimal environmental definition provides only general audio cues. Suitable for games where positioning isn't critical.

Treble is extremely rolled off and veiled. High frequencies are barely perceptible with significant loss of detail.
Dynamics E-
Extremely poor dynamic expression. Lacks any sense of impact or volume gradation, making music feel one-dimensional.
