KRK KNS Series Headphones - What's the difference?

We just added the KRK KNS-6400 and KNS-8400 Closed-Back headphones to our online store. KRK are well known for making great home and pro studio monitors but are relatively new to the studio headphone market.
These headphones have been getting great reviews! Performance, comfort, construction quality are all top notch and are very affordable at just $99.99 (kns-6400) and $149.99 (kns-8400).


What are the differences between KNS-6400 and KNS-8400 Headphones?
At first glance, the two models seem almost identical. By looking closely at the specifications you will see a few key differences. We've summarized these differences below.
Sensitivity: KNS-6400 will reach 95dB SPL before distortion. KNS-8400 does slightly better with a 97dB SPL rating.
Frequency Response: KNS-6400 = 10-22,000Hz; KNS-8400 = 5-23,000Hz
Isolation: KNS-6400 will isolate up to 26dB of ambient sound and the 8400's will isolate 30dB. (That's even higher than most 'isolation' headphones. Very impressive.
Ear cushion type: The specs say the 6400 have 'Acoustic Cellular foam' and 8400 have 'Acoustic Memory foam'. As you can guess, the memory foam will conform to your head and ears better, improving isolation and comfort.
Cable type: The KNS-6400 have a detachable 2.5M cable. The KNS-8400 adds an inline volume trim.
Weight: The only slight negative for the KNS-8400 is that they are 30g heavier than the 6400 (232g vs 202g). Either could still be considered lightweight compared to other studio headphones.
