Наушники — Final Audio DX4000CL

The DX4000CL is a circumaural closed-back model with a cable from final, the Japanese headphone and earphone maker, and it went on sale on 15 April 2026 at USD 999. The CL suffix marks the closed version within the DX line, where this model sits between the DX3000CL at USD 599 and the DX6000CL at USD 1,999. It is offered in black only and replaces an earlier generation that used a silver headband.

Key specs that matter

The 40 mm dynamic driver in each cup has a diaphragm made from a composite of washi paper and carbon fibre with a free edge that has no conventional surround. Impedance is 37 ohm and sensitivity is 96 dB per mW. The detachable cable is the silver-coated C093, 2 m long, with a 3.5 mm two-pole plug at the headphone end and a 4.4 mm five-pole balanced plug at the source end, and final packs a 4.4 mm to 6.35 mm adapter. Earpads are 30 mm thick memory foam wrapped in synthetic leather and can be swapped by the owner. The housing is glass-fibre reinforced resin with a textured paint similar to camera lens bodies that resists fingerprints and scratches.

Engineering and use context

Behind the driver, a carved diffuser array inside the rear chamber breaks up parallel surfaces and scatters reflections, which is final's way of limiting the internal resonance that closed enclosures tend to trap. The glass-fibre resin front plate that carries the driver is chosen for stiffness. Assembly avoids glue wherever possible, and parts are held with O-rings and precision screws so that the headphone can be taken apart and repaired over a long service life. The headband is black stainless steel with an extended adjustment range for larger heads, and the hinges move without noise. Thick pads keep the seal intact for listeners who wear glasses, and the closed shell makes the model usable in shared rooms or while travelling where an open design would leak. Packaging is a plain white card box, and final does not supply a carry case or pouch with this model.

Pairing

Given its moderate load and high efficiency the DX4000CL asks little of the source, and the supplied cable suits a balanced output on a desktop amplifier or digital audio player. The adapter covers single-ended home amplifiers without buying a second cable, and because the headphone side uses a standard two-pole socket, aftermarket cables with other terminations fit as well.
