There is something rather satisfying about a company that refuses to accept the usual limitations of a product category.
Closed back headphones have, for years, carried a certain reputation. Powerful bass, yes. Isolation, certainly. But also a tendency toward congestion, a slightly boxed in presentation, and a low end that can sometimes feel more enthusiastic than accurate.
Final has never really played that game.
With the launch of the DX4000CL, the Japanese audio specialist continues its mission to rethink what closed back headphones can actually do. Positioned between the DX3000CL and the flagship DX6000CL, this new model is not about excess. It is about refinement.
Closed Back, Done Properly
The DX4000CL takes aim squarely at the common criticisms of closed back design. Instead of leaning into boosted bass and a narrowed soundstage, Final has focused on balance, control and space.
The low end is disciplined and articulate. There is weight when the recording calls for it, but no unnecessary rumble clouding the midrange. Vocals emerge with a natural presence. Instruments carry convincing body and texture. Subtle details are allowed to breathe.
What is particularly impressive is the sense of openness. Despite being fully closed back, the DX4000CL presents music with an unexpectedly expansive stage. There is air between instruments. Complex passages remain composed. It feels resolving without tipping into analytical sterility.
That balance, between technical precision and musical engagement, is where this headphone appears to find its identity.
A New Dynamic Driver at the Core
At the heart of the DX4000CL sits a newly developed 40mm dynamic driver featuring a paper carbon composite diaphragm. The focus here is controlled diaphragm movement and carefully managed airflow within the housing.
The internal acoustic structure has been tuned to suppress unwanted resonance. Resonance is what turns a dense mix into a blur. By keeping the enclosure under control, Final allows the DX4000CL to retain clarity even when the music becomes busy.
The result is a presentation that is richly textured yet neutral. There is no obvious frequency range shouting for attention. Instead, everything feels proportionate.
Final includes a silver coated cable as standard, terminated in 4.4mm with a 4.4mm to 6.3mm adapter. The aim is improved signal transmission and a greater sense of transparency, complementing the headphone’s open and resolving character.
Where It Sits in the Lineup
The DX6000CL remains the summit of the range. The DX3000CL introduced many listeners to Final’s distinctive closed back philosophy.
The DX4000CL feels like a thoughtful midpoint. It leans into openness and precision while retaining the tonal richness that defines the DX series. For listeners who want a high end closed back that does not behave like a typical closed back, this could well be the sweet spot.
