Too shouty and lacks the bass emphasis to balance it out. Precogvision Youtube Channel
CCA Polaris Reviews
Has some massive issues in the air. Jaytiss Youtube Channel
Overall clean and balanced sound, but pinna gain is too much at higher volumes making vocals sound shrill and thin. Mid volume is nice, but KZ, so. Jays Audio Youtube Channel
