Final Audio DX4000CL Closed-Back Dynamic Headphones

The Final Audio DX4000CL is designed for listeners who want spacious sound with closed-back isolation. Built around a newly developed 40mm hybrid diaphragm, the DX4000CL combines paper and carbon fibre materials to deliver fast transient response and a natural tonal balance. This lightweight yet rigid design helps preserve detail across your music while reducing unwanted distortion.

To create a more open listening experience, Final has equipped these headphones with a Rear Diffuser Array, Spider-web Diffuser, and an internal airflow management system. Together, they help produce a wider soundstage with accurate imaging, while keeping bass controlled and mid-high frequencies clear.

The fibreglass-reinforced resin housing improves mechanical stability and helps minimise vibrations that can affect audio quality. For long listening sessions, memory foam earpads provide a secure and comfortable fit, even if you wear glasses. A detachable silver-plated OFC cable is also included, helping maintain a clean and reliable signal path.
