eXtra 10 headphones are a combination of lightweight, half-closed headphones and a modeling plugin for binaural perception. With the included dSONIQ Realphones ESI Edition, you'll get true studio control room sound with your headphones, no matter where you are.

Optimally adapted

The physical characteristics of the eXtra 10 form the basis for the adaptation of the popular dSONIQ software. Through months of fine-tuning, the ESI Edition has been optimally adapted to the ESI headphones down to the smallest detail. The result is a combination of solid audio hardware and an innovative technology that makes the sound reproduction as reliable and precise as a high-quality monitoring system in the studio.
