C-- Significantly flawed tuning. Noticeable frequency imbalances and unnatural timbre distract from music. Lacks versatility across recordings.
Average Technical Grade
C-- Limited resolution; finer nuances are masked. Soundstage feels narrow, and complex passages cause muddiness. Transitions lack finesse.

Fun, well tuned v-shape signature Details & Stage Tim Tuned Youtube Channel
High-clarity, potentially fatiguing sound with surprisingly good bass and treble extension. Precogvision Youtube Channel
Insane value. Still a bassy KZ, but for 15$, hard not to rec. Punches at higher price bracket, but still has 4.5k and 8k peaks for my library. I recomend EQing it - turns it into a beast for the price.
Big bass, big treble. A bit too spicy for my tastes Previously Owned

Surprisingly extended treble and good bass dynamics for the price. Just crappy tuning per usual. Precogvision Youtube Channel
