What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Very comfortable, especially the ear pads, which have an asymmetrical shape that seals behind the ear and allows adjustment for sealing against the side of the head
- Detailed, open, and free from confusion, compression, or distortion, revealing compromises in heavily compressed modern pop music
- Wide soundstage and good imaging, better than mid-fi headphones, with good width and separation
- Accurate bass that is clean, tight and fast with the energy of a really good speaker
- Construction is metal, with a nice finish to it
Product Considerations
- Adjustment for the headband feels bizarrely cheap
- Cable is subpar, with the same jack ending and quarter-inch adapter as lower-end AKG models, and it is difficult to make balanced
- Treble is very bright with a strong 6k peak and haze, hashiness, and sloppiness to the highs
- Mids lack warmth and have a very narrow peak that makes guitars sound harsh
- Open-back design means there is absolutely no isolation, making it unsuitable for libraries or trains
Comparisons (according to reviewers)
- Compared to the Sennheiser HD800, the K812 has more bass and a more involving midrange, but the HD800 has cleaner bass and better detail
- Compared to the AKG K712 Pro, the K812 offers a significant improvement in detail, openness, and overall refinement, and the bass is less blurry and indistinct
- Compared to the Audeze LCD-X, the K812 lacks the realism in the bass of the LCD-X but is more revealing with crystal clear and extended highs
- Compared to the AKG K712, the K812 is leaps and bounds beyond the 700 series regarding fidelity, soundstage, and transparency
Takeaway: The K812 is a comfortable and well-built headphone that offers a wide soundstage and detailed sound. The honest sound signature is well-suited for studio use, but it can also provide a rewarding listening experience for audiophiles.

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.

- Excellent resolution, while maintaining smooth treble
- Holographic stereo image, which contributes to its lifelike character
- Good layering and separation of instruments
- Incredibly wide and tall soundstage, providing a very dynamic experience
Product Considerations

- The 5kHz hump stretches vocals and make them timbrally thin at times
- Some reviewers express concern about the delicacy of the headphones and caution against dropping them
- The open-back design makes them unsuitable for noisy environments or situations where sound leakage is a concern
Comparisons (according to reviewers)
- The Arya is sharper, clearer, and better resolved than the HiFiMan Ananda, with a more open soundstage, but the Ananda has more bass grunt

- Vs Sennheiser HD650: The Atrium overall tuning is very reminiscent of the Sennheiser HD 650, where it is still fairly neutral, but it tends towards a little bit of warmth

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
- The mids are a standout feature, with vocals presented right up front
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
Takeaway: The Bravura headphone system is a great option for those who value detailed and natural sound, especially for genres like classical, jazz, and vocals. It offers a complete listening experience.
Video review
Our take on the brand
Our Summary
Product Strengths
- Clarity with refined control of the highs, and more forward mids that jump out for vocals and live jazz recordings
- Retains the warm, rich bass, with some extra energy to how it punches
- Smooth character of sound, a sense of refinement
Product Considerations
- New models mean new prices
- Some might be fine with the cheap plastic covers that must be removed before each listening session, and the increased risk to the drivers themselves
- The new Unveiled designs remove any kind of protection from the backside of the drivers
Comparisons (according to reviewers)
- The Aria Unveiled has a sense of refinement that the previous Arias did not have, it is improved in pretty much every way
- The Aria Unveiled cannot keep up with the technical performance of the HE1000SE, tonally, the Aria Unveiled might be preferable to some people over the slightly brighter sounding HE1000SE
Takeaway:
The Aria Unveiled offers a balanced and refined sound, making it a versatile choice for various music genres and preferences. Improved clarity and controlled highs create an enjoyable listening experience.
