Final has priced its new closed-back flagship headphone at nearly £8,000, placing the DX10000 CL among the more expensive headphones on the market.
It has a closed-back design which brings inherent challenges to reproducing sound, since sealed enclosures trap reflected sound waves that colour tone and create the cupping effect associated with less expensive headphones. This is a problem Final has set out to address with its new flagship.
Addressing that problem starts with the driver itself. Final has developed a new 40mm True Diamond diaphragm dynamic driver whose centre dome is grown as a crystalline diamond layer using a Chemical Vapor Deposition process.
The diamond dome combines exceptional rigidity, high sound velocity and strong internal damping, properties that let the diaphragm maintain accurate piston motion while suppressing residual vibration once the signal stops.
Supporting the dome is a newly developed polyurethane surround alongside a lightweight polyimide bobbin-integrated voice coil, additions Final paired with an N55 neodymium magnet and aluminium shorting ring to control distortion.
Beyond the driver, DX10000 CL relies on a housing precision-machined from an aluminium-magnesium alloy using 5-axis CNC technology, an approach that treats the enclosure as part of the acoustic design rather than a simple shell.
Rigidity of that kind proves essential since even minor vibrations or air leaks can alter the enclosed air volume and affect the resulting sound, prompting Final to fill internal cavities with dedicated damping material.
Rather than sealing the ear chamber completely to maximise isolation, a method that can push designers toward exaggerated treble to restore balance, DX10000 CL uses Ultrasuede earpads with carefully controlled air permeability.
That approach lets the earpads manage internal air pressure naturally while maintaining an effective acoustic seal. Final has paired the Ultrasuede covering with a specially selected foam chosen for comfort and consistent acoustic response.
Longevity also shapes the design since DX10000 CL uses a 12-point through-bolt construction in place of adhesive assembly, and the screw-fastened structure lets owners disassemble and rebuild the housing whenever servicing becomes necessary.
Alongside the housing and driver assembly, DX10000 CL ships with two Final cables co-developed with Junkosha, a specialist manufacturer known for high-performance cable engineering, plus two conversion adapters covering XLR and 6.3mm connections.

Alongside the standard model, Final is releasing the first 150 DX10000 CL units worldwide as a Collector’s Edition finished with gold-coloured accents and presented inside a traditional Japanese paulownia wood box.
That edition also includes an original Shingen Pouch crafted from Tango Chirimen, a traditional silk textile woven in the Tango region of Kyoto, alongside a CNC-machined aluminium stand designed to display the headphone.
Pre-orders for DX10000 CL opened on 9 July, with the Collector’s Edition priced at £7,999 / €8,999 / $8,999 and the standard edition, supplied in Final’s existing D Series carrying case, priced at £7,499 / €8,499 / $8,499.
