Video review
Our take on the brand
Product Strengths
- Excellent bass reproduction with well-textured low tones, exceptional definition, articulation, and clean, nuanced deep sub-bass extension.
- Detail retrieval and image clarity are remarkably good, competing with some of the very best headphones in the summit category.
- Outstanding build quality, featuring a precisely machined aluminum-magnesium alloy chassis, conveys sturdiness and care in assembly.
- The new pads are made from Toray Ultrasuede and are deeper and marginally firmer than the original memory foam cushions.
- Easy to drive, with 60-ohm impedance and 98 dB sensitivity.
Product Considerations
- A bit scooped out in the two kilohertz to three kilohertz range, almost like the ear gain has been taken and moved upwards in the frequency spectrum a bit.
- Comfort can be an issue, due to the circular earcups not fitting larger ears well and the headband lacking sufficient padding for the headphone's weight.
- The stock cable with the quarter-inch termination is heavy, potentially dragging the headphone down uncomfortably.
- The proprietary 3.5mm connectors with locking mechanisms can make finding aftermarket cables difficult.
Comparisons (according to reviewers)
- Compared to the HIFIMAN Susvara, the Susvara is lighter, more comfortable, and also has better detail retrieval.
- Compared to the Audeze LCD4, the Final Audio D8000 Pro competes in many of the technical aspects that really matter, like detail.
Takeaway: The D8000 Pro is a well-built, detailed headphone with exceptional bass and a unique planar sound signature, perfect for audiophiles who want something different from standard planar sound profiles. Its high level of detail and solid dynamics create an engaging listening experience for those who appreciate nuanced sound.

Video review
Our take on the brand
Our Summary
Product Strengths
- Comfortable to wear for extended periods, thanks to plush, soft earpads and a generously padded headband, although some found the clamping force substantial
- Delivers a natural, transparent, and detailed sound, a hallmark of electrostatic headphones
- Good bass response, with impact that is noticeably improved compared to the Sonoma M1
- Excellent instrument separation is highlighted, creating a sense of sounds floating around the listener's head

Product Considerations
- The complete system (headphones and amplifier) is required because of the unique voltage requirements, it's not possible to mix-and-match components with other systems
- Some reviewers found the cable to be stiff and microphonic, although its unique character and design are a result of the system's electrostatic nature
- The volume control on the Sonoma M1 energizer/amp offers only stepped adjustments, making fine-tuning volume levels difficult for some users
- The power switch is located on the back of the Sonoma M1 amplifier, which is considered less convenient than a front placement
- The headphone still retains some excess clamping force
Comparisons (according to reviewers)
- Vs Sonoma M1: The Bravura offers enhanced SPL, more robust bass, and increased resolution compared to its predecessor, the Sonoma M1
- Vs Dan Clark Audio VOCE: The Bravura offers more impactful bass
- Vs HiFiMan Shangri-La Jr.: The Bravura offers a smoother sound
