Verdict upfront: a statement closed-back for a tiny niche
The Final DX10000 CL is an ultra-premium closed-back audiophile headphone built around a True Diamond dynamic driver, designed to offer expansive, immersive sound, luxury construction, and long-term serviceability at a price that firmly targets serious, well-equipped headphone enthusiasts rather than casual listeners. At USD 8,499 (approx. RM39,000) for the standard edition and USD 8,999 (approx. RM41,000) for the first 150 Collector’s units, this is not a rational upgrade from mid-tier closed-back headphones. It is a statement luxury audiophile headphone for people who already own high-end amps and DACs, want isolation without giving up scale, and are comfortable paying flagship loudspeaker money for premium flagship headphones. From that vantage point, the DX10000 CL delivers a spacious, powerful sound and exceptional comfort, but its price and closed-back limitations mean it will feel excessive or compromised for many listeners.

Engineering: True Diamond drivers in a tough closed-back format
Final’s headline claim is simple: build premium flagship closed-back headphones around a 40mm True Diamond diaphragm dynamic driver and tame the usual closed-back problems of resonance and coloration. The center dome is grown using Chemical Vapor Deposition, forming a self-supporting diamond layer instead of the more common diamond-like carbon coating. Diamond’s high rigidity, high sound velocity, and strong internal damping are meant to keep motion pistonic, reduce deformation, and limit residual vibration when the music stops. Around that diaphragm sits a redesigned driver system: polyurethane surround, lightweight polyimide bobbin-integrated voice coil, free-floating lead wires, N55 neodymium magnet, aluminum shorting ring, and internal damping tuned for lower distortion. All of this sits inside a high-rigidity, airtight aluminum-magnesium alloy housing, milled with 5-axis CNC; excess material is carved out to reduce weight, with the resulting cavities filled with acoustic damping to control rear-wave reflections, a key challenge for closed-back headphones.
Pros
- True Diamond diaphragm with CVD-grown dome offers a rare, technically ambitious driver design among diamond driver headphones.
- Carefully damped aluminum-magnesium closed-back housing directly addresses isolation and resonance limitations typical of closed-back headphones.
- 20-ohm, 92 dB/mW spec keeps them relatively approachable to drive compared with ultra-high-impedance rivals, while still benefiting from strong amplification.
Cons
- Diamond diaphragm and complex driver system raise expectations dramatically but do not fully remove closed-back constraints on soundstage width.
- Ultra-specialized engineering is overkill for listeners without a high-end desktop source chain, limiting the real-world benefit of the design.
Design, comfort and long-term ownership
For luxury audiophile headphones at this level, build quality and comfort matter as much as the tech. The DX10000 CL uses a silver-accented aluminum-magnesium alloy housing, with unnecessary material removed to keep weight manageable and internal cavities filled with acoustic damping. It weighs 543 grams, but Ultrasuede earpads take up a large portion of the ear cup area and feel like “two couch cushions on your head”, with soft foam and a supportive headband distributing clamp pressure well. The earpad material is chosen for controlled air permeability to hit Final’s intended acoustic response while staying comfortable during extended listening. A 12-point through-bolt construction uses screws instead of adhesives, so the housing can be disassembled and parts replaced; that matters when the standard version costs USD 8,499 (approx. RM39,000) and the Collector’s Edition USD 8,999 (approx. RM41,000). The Collector’s Edition adds gold-colored accents, a paulownia wood box, silk pouch, and a CNC-machined stand for extra visual drama. This is clearly built as a long-term, serviceable flagship, not a disposable fashion piece.
Sound: expansive, immersive, but still closed-back
On the ear, the DX10000 CL sounds like it is trying to break out of the closed-back headphones category without abandoning isolation. Its soundstage has impressive depth, stacking layers of instruments front to back with convincing scale, while height adds to a tall, cavernous impression when properly driven. Width is less spectacular, with the stereo field reaching far enough to feel immersive but not fully open-back in its spread; the limits are audible, even if easy to ignore once you settle into the presentation. Tonally, bass is full and natural rather than boom-happy, delivering weight without taking over. The midrange is bold and expressive, sometimes so forward that certain elements can dominate your attention when you want to focus on other parts of the mix. Treble adds brightness and air to keep the sound lively but stays refined, avoiding harshness. In short, these premium flagship headphones aim for powerful, immersive listening that still keeps clarity and natural tone at a reference level.
Value: who the DX10000 CL is really for
The DX10000 CL exists above most of the high-end field: rivals at USD 4,000–6,000 (approx. RM18,000–27,000) now look almost sensible next to its standard USD 8,499 (approx. RM39,000) price and USD 8,999 (approx. RM41,000) Collector’s edition. This is not a headphone for casual curiosity; its cost and requirements place it firmly in niche statement territory. In return, you get diamond driver headphones with expansive, immersive sound, full but controlled bass, expressive mids, and refined treble, plus plush comfort, silver-coated cables, and a serviceable chassis designed for long-term ownership. But closed-back format limits mean soundstage width and ultimate openness still trail the best open-back luxury audiophile headphones, and its midrange forwardness can be too insistent for strict neutrality. According to one review, “for those looking for a closed-back audiophile headphone with serious technical ambition, the DX10000CL delivers a sound that feels expansive, immersive, and richly detailed”. If that description maps to your priorities and budget, Final’s most ambitious closed-back project has a clear audience; everyone else should admire from afar.
- Buy the DX10000 CL if you want closed-back headphones that deliver expansive, immersive sound with full bass, bold mids, and airy treble in a single flagship package.
- Skip the DX10000 CL if you mainly value ultra-wide, open-back soundstage and absolute openness over isolation and closed-back impact.
- Buy the DX10000 CL if you already own a capable desktop source chain and want diamond driver headphones that explore the limits of closed-back engineering.
- Skip the DX10000 CL if you are a casual listener or are not prepared to spend USD 8,499–8,999 (approx. RM39,000–41,000) on a single pair of premium flagship headphones.
- Buy the DX10000 CL if long-term comfort, Ultrasuede pads, premium silver-coated cables, and a screw-assembled, serviceable housing are key parts of your luxury audiophile headphones wish list.
- Skip the DX10000 CL if you prefer a more relaxed, less forward midrange presentation and do not want vocals or central instruments to dominate your focus.
