Final Audio DX6000 Review: High Impedance, High Impact

Final Audio doesn't include much but the bare-bones essentials in its packaging. The contents are as follows:

• DX6000 Headphones
• Hard Case
• Cable: 3m OFC Cable with XLR 4pin Connection

While accessories may seem lacking, the DX6000 holds a confidence that the headphone is impressive on its own. It doesn't need flashy adapters or special convertors for you to know this is a high quality headphone. 

These headphones carry the same visual aesthetic as most other headphones in the D-series from Final Audio. With a magnesium alloy outer dome, you get a shiny exterior that stands out against black washi-paper earpads. The stock cable is a 4-pin XLR termination, though the detachable cable makes it easy to replace with a cable and termination of your choosing if you want to skip the adapter.

The fit of these headphones screams comfort. It’s a bulkier headphone, yes, but the soft earpads and washi-paper material that covers your ear completely is light and breathable. The adjustment is smooth and fits perfectly to any size head.

Driving these headphones is a little more difficult. According to Final Audio, the DX6000 is marked with a nearly 480 Ω impedance rating, so they’re going to require quite a bit of power to get the full sound out of. While some high-end portable amps may be able to do the trick, Final recommends getting a heavier-duty desktop amplifier to enjoy the headphone at its finest. 

For my listening, I opted for a mix between high-end transportable DAC/Amps and desktop equipment. The results were aligned with what Final Audio recommended. DACs like the FiiO K11 R2R and the iFi Valkyrie were ideal for giving enough power to drive these cans, while smaller portable devices like the BTR17 or a simple iFi GO Link Max really didn't do the trick.

Soundstage 

The soundstage is decent in width and depth, not so much height. The sound is really immersive, with frequencies wrapping around your head and fading into your environment for the optimal listening experience. The imaging accuracy is quite nice, so you can really picture the elements around you as you listen. The sound signature definitely leans towards the bass, and the relaxed tone invites a loss of clarity that some people may not appreciate. For those looking for a laid back listen, this headphone will definitely let you relax and give you a good background sound for everyday listening. If you're after something more detailed, perhaps look at Final's other headphones. 

Low Frequencies

The low end is particularly thick and has a large body that takes up a lot of space in the sound signature. It really carries a lot of weight and heaviness that is most noticeable in subbass rumble and 808 kick drums. Bass lines get extra thickness and coloration, though it makes instruments in this range a bit washed and you lose some clarity. Still, you get excellent tonal balance and timbral detail, so you can tell what instruments are what. It is a deep sound that becomes pretty powerful in any genre.

If you're not a fan of strong bass, these headphones may not be for you; there is a lot of low end sound that is the bulk of the sound signature. People who prefer a lighter listen will likely steer clear of these. 

Midrange Frequencies

The midrange comes in towards the front of the mix, which makes vocals and some melodic instruments stand out. There is a lot of textural elements that get a smoothed out tone, so there isn't much punchiness in this range. Instead, you get some decent clarity with the timbre and tone. I really like how everything is tuned in this range, and vocals come out natural and relaxed in any genre of music. Indie music is a great choice for these headphones, or R&B. You get a sound that is warm and inviting, relaxed and smooth which leans into those genres. The midrange has nice depth to it as well, so the layers of sound get decent separation and fill the space for immersive listening. 

High Frequencies

The high end is more recessed compared to other ranges, but still has decent detail to be noticeable and balancing. The clarity that you may find is lacking in other parts of the signature come through immensely here, so the top end sparkles with color and clarity. It isn't as powerful as the low end or the midrange, but it's enough so the low end isn't the only thing you hear. You can get enough contrast from the top end to get a whole picture, and while you may still want more frontal sound, a simple EQ on your amp/DAC will help achieve that. 

The Final Audio DX6000 is a unique headphone crafted for those who prioritize warmth, depth, and immersion in their listening experience. With its strong low-end focus, lush midrange, and soft treble, it’s a headphone best paired with a powerful amplifier and a relaxed mood. While not ideal for fans of hyper-detailed or neutral sound, it’s an excellent choice for ambient genres, hip-hop, R&B, and indie. If you’re looking for a premium headphone that blends luxury aesthetics with a bold, bass-rich signature, the DX6000 is worth considering.
