Customer Review Summary
Introduction to the HIFIMAN SUNDARA Silver
Released in July 2019, the HIFIMAN SUNDARA Silver is an open-back, over-ear headphone designed primarily for accurate sound reproduction. With a retail price around £219, it aims to deliver high-end audio performance at a competitive price point. The model number 470072 distinguishes this version, which is notable for its planar magnetic driver technology and solid build quality.
Design and Build Quality
The SUNDARA Silver features a largely aluminium and metal construction highlighted by a silver-tone headband and earcup frame, contributing to its robust feel. Weighing approximately 355 grams, it strikes a balance between substantial presence and comfort, though some users with broader head shapes might find the clamping force firm. Adjustable headband increments help tailor the fit.
Ear cushions are covered in black synthetic leather and offer a good seal around the ear, though their size and shallow depth may not suit everyone, with some recommending aftermarket pads for more comfort, especially for larger ears.
The cable is replaceable, comprising a detachable 3-metre flexible dual-side routed cable terminating in a 3.5 mm stereo mini-jack with an included 6.35 mm adapter. Although the stock cable is adequate and tangle-resistant, it falls somewhat short in terms of premium feel and durability, prompting many users to upgrade to higher-quality or balanced cables for optimal performance.
A travel case and a manual (available online) accompany the headphones, though the packaging is utilitarian rather than luxurious.

- Sensitivity: 94 dB SPL
- Connector: Removable 3.5 mm stereo mini jack, includes 6.35 mm adapter
Sound Quality Assessment
Returning users and professionals alike praise the SUNDARA Silver’s highly neutral and balanced sonic profile. Its planar magnetic drivers offer impressive transient response and detail retrieval, closer to very expensive models but at a fraction of the cost.
The bass is articulate and precise, providing enough depth for most listeners without exaggeration, though those seeking sub-bass extension beyond standard may find the low end restrained. Interestingly, some reviewers noted an improvement in bass response by slightly lifting the headphones off the ears, possibly relating to earpad fit and seal quality.
The midrange clarity is exemplary, with vocals and instruments positioned naturally and clearly in the soundstage. Critics note a minor dip around 2-3 kHz which can render vocal presence slightly recessed compared to some competitors, but this results in a less fatiguing listening experience over extended sessions.
High frequencies are smooth and well-resolved without fatigue, avoiding harsh or sibilant presentation common to brighter headphones. This “softened” treble contributes to the headphone’s suitability for mixing and mastering tasks.
The soundstage is moderately wide with a convincing sense of space and layering that surpasses many contemporaries in its price bracket, creating an impression of sound “in front” rather than “inside the head.” This helps with precise spatial placement of sound elements.
Comfort and Ergonomics
The open-back design confers a noticeably airy and spacious listening environment, but it also means these headphones are unsuitable for noisy or shared environments due to sound leakage. Comfort is generally rated as very good by most users, with the softly padded headband and earcups enveloping the ears well. Some with larger heads experience some discomfort from clamping pressure, which can often be adjusted manually.
Practical Considerations
The SUNDARA Silver is relatively portable, coming with a travel case, but its open-back nature and cable are not ideal for mobile use. Cables tend to be slightly stiff, and the lack of noise isolation or attenuation limits practical outdoor or public transport usage.
Maintenance and longevity are strong points. Replacement earpads and cables from HIFIMAN and third-party manufacturers ensure long-term usability. The straightforward 3.5 mm connectors avoid exotic proprietary cables, increasing compatibility and reducing cost of ownership over time.
Compatibility and Amplification
With an impedance in the low 30s Ohms and sensitivity around 94 dB, the SUNDARA Silver can be driven by many common devices including laptops and desktop soundcards, though it benefits significantly from quality headphone amplifiers. Many user experiences highlight marked improvement in dynamics and detail with dedicated amps capable of matching impedance levels, such as dedicated HiFi amplifiers.
Conclusion
For approximately £219, the HIFIMAN SUNDARA Silver offers exceptional sonic performance that competes with higher-end models costing several times more. It is particularly well suited for critical listening, mixing, and mastering due to its neutral tonal balance, detailed retrieval, and expansive soundstage.
Though comfort and cable quality could see improvements, the overall package presents excellent value. Its robust build and upgradeable components further increase its appeal to audiophiles seeking a long-term investment.
Where the SUNDARA Silver truly excels is in delivering a transparent listening experience without auditory fatigue, making it a strong recommendation in its price category for those prioritising fidelity and accuracy over portability or casual use.
