Summary: KRK Systems have intentionally ruined our reference frame for closed back mid-end headphones by sneaking in the KNS 8400s. Not only do they block out a good amount of noise, their sound signature is extremely pleasing to boot. The fact that they can be driven by pretty much any PMP or sound card on the market makes them extremely good value for money. Gaming performance wise these are right up there with the über expensive BeyerDynamic MMX 300s.
Pros: Low weight, Memory foam pads, Durable construction, Closed back design (higher than average ambient noise attenuation), Balanced sound signature, Comfortable to wear, Can be powered out of normal quality sources, Volume control, Replaceable cable, Great bundle, Great price / performance ratio, Versatile, Normal looking
Cons: Normal looking, Cable not ideal for use on the move, and no options available from KRK Systems, Bass will not satisfy bass-heads, Cable not the least microphonic out there
Excerpt: Whether or not you can create a good mix using headphones is one of music technology’s on-going debates; you’ll find countless discussions on forums across the internet. Whichever side of the fence you fall on, there’s no denying that checking your mixes on a quality set of’phones can sometimes be the only way to home in on subtle problems in a track.
