    Premium monitoring

    Detail, clarity, flat response and honesty. The KNS6400s are the result of KRK listening to the wants and needs of high profile industry figures. This allows you to own a high quality product that will improve your recording, mixing and mastering without breaking the bank.

    The KNS series have been devised, developed and tuned to the same standard as professional brand studio monitors. The flat, frequency response of the 6400s will enable to hear truth in your recordings, free of enhancement or colouration. Mix and master with confidence knowing that by using the KRKs your work will translate perfectly across all systems.

    The KRK KNS 6400s are rapidly becoming the top choice for many within the music industry for good reason

    Consistent sound regardless of location

    Whether in the studio or on the go, the KNS 6400s remove the anxiety of working in acoustically inadequate spaces. Whilst it is ideal to work on monitors in an acoustically treated environment this may not always be financially or logistically possible when mixing and mastering.

    KRK's response to this dilemma is to create headphones that offer consistent, honest and premium sound reproduction, regardless of location.

    Comfortable for heavy duty usage

    KRK's decision to include isolating memory foam in the ear cushions helps to provide detailed low-end response. Over time the foam will subtly conform to your unique head shape. This will be great in providing you comfort for sessions when you’re required to work for long hours with minimal down time.

    The closed back nature of the KNS 6400s offers excellent isolation, making them great for musicians to wear when tracking. The comfortable fit and detailed sound will inspire any musician to give their best performance, ultimately making your job easier!
