VRM overcomes the major obstacle for mixing with headphones by giving you multiple perspectives on your mix, as if you were listening through speakers. Noise levels from mixing through speakers can make it impossible for most to mix at home, especially without annoying the neighbours. With VRM, you can mix any time, anywhere. Using any pair of monitoring headphones, VRM lets you choose your mixing environment from a living room, a bedroom studio, or a professional studio. You then simply choose from a list of 15 industry-standard studio monitors and speakers.

VRM Box delivers audio quality worthy of your headphones. Boasting a dynamic range of 108dB, it provides a sound that's more precise, with lower distortion and is far superior to built-in laptop headphone outputs. The compact size and robust build quality of VRM Box means it's ready to go anywhere, any time.

The VRM Box functions as a high-quality 24- bit/48kHz USB audio playback interface. So, whether you're mixing, creating music or simply listening to tracks, Focusrite's VRM Box is perfect. What's more, there's no need for a power supply or batteries, because it gets all the power it needs, with full audio quality, from your computer's USB port. VRM Box also features a digital (S/PDIF) input, which supports sample rates up to 192kHz. This allows you to run it in conjunction with your Pro Tools HD system, or any other interface with an S/PDIF output.

Make the most of your headphones

With a dynamic range of 108dB (A-weighted), VRM Box provides a significant audio upgrade from low-grade laptop headphone outputs (which commonly only provide around 92 or 93dB), with an audio quality the equal of interfaces ten times its price.


"VRM provides a valuable resource, both for those who monitor on headphones and for the rest of us who enjoy the reassurance of varied monitoring environments" - MusicRadar

"Within five minutes of plugging it in, I had become aware of all sorts of things that were wrong with my mixes. I will certainly be buying a VRM Box. I can't think of any other affordable product that has made more difference to my own mixing. - Sound on Sound
