Ventilation Pad System (VPS)
This configuration includes all open ducts and maximizes the perception of detail, wide soundstage and control of the bass range. It is also particularly suitable for tubes amplifiers.
This configuration is designed for those who want to listen essentially to the recording without any modification, or for those who work with music and need the highest degree of fidelity in the timbre. In this configuration the filter is inserted in the compensation port and makes the bass range more full-bodied, preferring a current-driven amplifier.
This configuration with three closed ventilation holes and the inserted filter makes the headphone more isolated from the outside and the bass range even more dynamic and suitable for use in environments with high background noise. Ideal for Rock and live effect electronics.
