The closed-back, circumaural (“around the ear”) design provides up to 30 dBA of isolation, which significantly reduces headphone “bleed” into the microphones when recording. The excellent isolation performance also lets you focus on the music, without distraction from external sounds. With a maximum SPL of 124 dB, they’re capable of providing all the level you’ll ever need while remaining clear and detailed sounding, with very low distortion. KRK headphones are a reference that professional engineers trust. Their accurate frequency response, excellent stereo imaging, and consistent KRK voicing means that you can rely on them for the most critical listening applications.
