Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- oBravo utilizes a hybrid driver configuration, combining a dynamic driver for lower frequencies with a specialized Air Motion Transformer tweeter for enhanced high-frequency performance.
- They are known for crafting their IEM and headphone housings from premium and often unusual materials such as brass, ceramic, wood, and copper, selected for their acoustic properties and aesthetic appeal.
- oBravo's products often feature a semi-open design that aims to provide a more spacious and speaker-like listening experience compared to traditional closed-back IEMs and headphones.
- They engineer and patent their own proprietary AMT drivers, including the AMT II, continuously striving to improve the performance and efficiency of their unique tweeter technology.

Our Summary
Product Strengths
- Outstanding sound quality with clarity, texture, and detail
- Natural sound provides a you-are-there presence
- Improved microdynamics make them quick and fast
- Easier to drive than the original Susvara due to a changed metal trace on the diaphragm
- Very comfortable, with good weight distribution
- Driver is exposed, making it vulnerable to damage
Product Considerations
- Can be unforgiving on poor recordings
- Lacks soundstage depth and layering compared to some competitors
Comparisons (according to reviewers)
- Vs Mesa Elite: The Mesa Elite offers greater bass weight and depth in the soundstage
- Vs Audeze LCD-5: The LCD-5 provides more insight into the music, but the Susvara Unveiled excels in reproducing the attack and energy of plucked strings and in bass reproduction
- Vs Focal Utopia 2022: The Utopia balances everything well—tonality, punch, detail, staging—however both have a little edginess from the treble
- Vs HiFiMan HE1000 Unveiled: The HE1000 is brighter and seems a little faster and more detailed, but the Susvara Unveiled is smoother
- Vs Original Susvara: The Unveiled model is more agile and lively, with added energy, clarity, and upper-treble extension, and the original is more laid back
Takeaway: The Susvara Unveiled provides detail and resolution that one has likely never heard before, making them astonishing headphones. If the priority is a reference-style tuning for orchestral music with excellent balance, scale, and tonal response, these headphones can provide a massive sonic treat.

Our take on the brand
Our Summary
Product Strengths
- Offers a combination of electrostatic resolution with dynamic timbre and planar bass extension, delivering the 'best of all worlds'
- The build quality is superb, with premium materials and craftsmanship that surpass competitors
- Delivers perfectly extended bass with a planar-like slam, with detail, texture, and physicality
- Has a wide soundstage with excellent imaging that creates a holographic feeling of voices and instruments, with a true 360-degree experience
- Very comfortable to wear, despite being somewhat heavy, with good weight distribution and no hot spots
Product Considerations
- Requires a powerful headphone amp to get the most out of it, due to the need for a current drive interface/transformer
- The weight (610g) may be a concern for some users, though the weight is distributed well
- Some vocalists, particularly some female vocalists, may sound more distant than desired
- Bad mastered songs tend to immediately show problems
- Frequency response is dependent on synergy with the amplifier
Comparisons (according to reviewers)
- Vs HIFIMAN Susvara, it combines the weight of the original Susvara with the soundstage and resolution improvements of the Susvara Unveiled—more power is needed
- Vs Abyss 1266, it has more body of sound, smoother highs, and tighter, more natural bass, while the Abyss has a wider soundstage, better positioning, and more bass impact
- Vs Dan Clark Audio Stealth, it has a wider soundstage and feels more effortless, and is more open, while the Stealth is closed, has more bass quantity, and a more pleasing treble
- Vs RAAL-requisite CA-1A, it improves upon the CA-1A in terms of body of sound, bass, and timbre, while remaining comfortable, and the CA-1A has a lighter and more forward soundstage
Takeaway: The Immanis is an exceptional headphone that blends various sonic qualities together, boasting great build quality and an immersive sound experience. With the right equipment to support it, one can enjoy a detailed and spacious sound that makes it a top contender in the flagship headphone market.
