The VE ONE, VE PRO and VE ZEN models use dynamic drivers. In order to fully exploit the sound potential of a dynamic driver, these models require a pressure relief valve (PRV), which enables the necessary pressure compensation in the housing. This PRV is integrated into the faceplate of each of the models mentioned, regardless of the design selected.
The PRV has no influence on the damping of the In-Ears but is rather a vent in the housing, not in the ear canal itself.
Dynamic drivers work on the principle of a small speaker: a diaphragm is set in motion by a spool, which generates sound waves. This movement creates air pressure inside the shell. If this pressure cannot escape, a so-called pressure build-up occurs, which restricts the freedom of movement of the membrane. This leads to several problems such as reduced bass reproduction or an unnatural sound.
To prevent this and ensure the full sound of the dynamic driver, the PRV is integrated into the faceplate. This ensures pressure compensation, allowing excess air to escape without making the sound audible to the outside.
