When Equation decided to do headphones, we spent a long time listening to the best headphones that money can buy. We listened to all kinds of music, and in a variety of conditions. What we came up with is the Equation RP series of headphones. We believe that quality and performance should be available to everyone. Try a pair for yourself and find out why Equation Audio is "beyond equal."
