You demand a lot from pro headphones, and the KRK KNS 8400 closed-back monitor headphones deliver. Voiced to remain true to the character of KRK's class-leading studio monitors, the 8400s are designed to be a true reference monitor, allowing you to record and mix the same way you would using speakers. Exceedingly accurate, the 8400s have a natural, wide frequency response with a silky, articulate high end, as well as extended low-frequency definition that ensures that the bass component of your music is accurately reproduced. And the robust dynamic range exhibited by the KRK KNS 8400s serve up consistent low-distortion detail and clarity.

Traditionally, having to switch from speakers to headphones has represented a disconnect of sorts in the recording process. You often find that those comfortable, ruggedly built headphones you love bear little sonic resemblance to your trusted monitor speakers. Drawing upon their 20-plus years of experience in studio sound, KRK has solved this dilemma with their KNS series headphones. Happily, going to headphones is no longer a jarring experience!

The KRK KNS 8400s usher in a new standard in headphone comfort - even over extended periods of use. The 8400's circumaural design employs high-tech memory foam ear cushions, allowing them to conform to your ear to help ensure a comfortable fit during marathon sessions. KRK has thoughtfully spec'd these 'phones with replaceable parts, including a detachable high-durability oxygen-free copper cable with an in-line volume control. Delivering accuracy, comfort, and reliability, these puppies are designed from the ground up for pro monitoring so you can trust your headphones as never before.

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
