KRK KNS8400 Studio Headphones are truly a real value of professional studio headphones for an affordable price.

KRK KNS-8400 reviewKRK Systems might be better known for their monitors but they are manufacturing some real good monitor headphones.

The sound quality they deliver can hardly be beaten by other headphones in the same price range. They offer an accurate, clear and neutral sound, with low distortion and excellent frequency response. A very good choice for a ‘beginner’ or for any producer on a budget!




The KRK KNS8400 might be built out of plastic, they are manufactured to last. They are relatively well built and very light. The headband is adjustable and the ear pads are made of memory foam are very comfortable. They are oval shaped, and big enough to fit your ears and leave some space. Right ear and left ear are clearly indicated by blue and red markers on the back of your head.

The ear pads can fold but only  flat, so not in the back or up which makes them not the best portable headphones. There is one cup that can flip around, which can be useful for DJ purposes.

KRK KNS-8400 reviewkrk4With the headphones you will get 3 cables, a long one which comes with a handy volume connector, that slights fluently a shorter one and a coiled cable. All cables and parts can be replaceable. They come with gold connectors, an 1/4 inch plug that you can unscrew to a 1/8 inch one.

With all this, you will receive a leather like carrying bag and a cleaning cloth.

The isolation is good but not optimal and there is some noise leaking at high volume.

How do they sound?

They provide a flat, neutral sound as EQ monitoring headphones are supposed todo. The sound is transparent and detailed and they have a consistent frequency response. The treble is flat and extends well.

They are very good in the mid-and mid highs. The mids are almost flat, crisp and clear. The soundstage is small and not amazing but better than the average for closed-back headphones.

 The best sound? No, there are some short comings , especially in the bass, that is not as powerful as one might expect. But these headphones are monitoring headphones and as such they try to deliver the most flat possible sound possible so that might affect the bass, that has intentionally not been colored. If you compare, Dre’s Beats, for example. Those have a heavy colored bass which might be great for listening but they are horrible when it comes to recording or mixing purposes.

Even thought they are not a reference in sound, they do offer very good conditions for studio purposes and do the job just well! The are certainly a value for the price and they can be considered a good alternative for the Audio Technica M-50x for if for cheaper. Preference still goes to the unbeatable M-50x though.
