The ov21 is our flagship, high-fidelity, studio monitor and our first ever over-ear design. When we set out to build the ov21's, our goal was to not only meet, but exceed the demands of audio professionals, musicians and music enthusiasts.

We spent countless hours testing and improving the design; repeatedly measuring prototypes against headphones more than three times their price. Each time, the ov21's came out way ahead. We can confidently say these headphones are giant-killers.
