KRK KNS 8402
The 40mm dynamic drivers deliver a wide 5Hz–23kHz frequency response, while closed-back isolation blocks up to 30 dBA of ambient noise for precise monitoring. Acoustic memory foam ear cushions and a lightweight 247-gram build ensure comfort through long sessions, with a handy in-cord volume slider. These are best for audio engineers and music producers who need accurate, fatigue-free monitoring during extended mixing sessions.
