Introduction

KRK Systems known for their studio monitors recently ventured into the headphone scene with the KNS 8400 and 6400 headphones. The headphones are designed as sturdy studio monitors for mixing and general studio use, but their qualities allows them to cover so much more than that. Frequency response is closer to flat than fun which both allows you to mix correctly, but also helps you pick up on small sound details in games. We take these $149 headphones for a spin and see how they fare both when it comes to music playback and gaming performance.
