Moreover, it does not color the audio so that you can differentiate between individual sounds.

The transducers of the planar magnetic headphones function effectively to capture fast percussive sounds. Thus, HiFiMan Sundara provides exceptional performance when it comes to dynamics, speed, and detail retrieval.

Ultra-Fine Diaphragm

The installation, processing, and diaphragm material production is quite complex as it requires creating a lightweight material and has high tensile strength. HiFiMan Sundara included both the qualities in the diaphragm.

Audio Quality


It’s time to get to the most crucial discussion: the sound quality of this exceptional planar magnetic headphone. The sound quality is divided into various categories including, Bass, Mids, Highs, Tonality, and Soundstage.


The bass of the headphone is quite linear sounding and natural. When it comes to performance, the headphone can provide a reverberant thump, usually a polite and clean thump.

The mid-bass induces a slightly warm touch as it is enhanced slightly, whereas the upper-bass is neutral and linear that prevents saturation and over-warming. Also, it offers excellent driver control where each note has a high definition and tight impact.

You shouldn’t assume a hyper-defined sound, but that offering a euphonic tone with amazing quality. You will not experience a hard-hitting at the bottom because of the mid-bass that makes the Sundara a musical headphone rather than being muddy or sloppy.


HiFiMan Sundara is known for its natural instrument presentation and warm vocals. That’s why the mids perform relatively well. The lower mids travel from the upper-bass linearly while providing warmth highlighting the vocal range. Furthermore, you get a neutral center mid-range that puts vocals behind the instruments.

The HiFiMan Sundara offers consistency in its character while maintaining a perfect balance between the bass and mid-range.


With a trouble-free rate and extension and excellent detail, this kind of level is unique to Sundara, which makes it stand out among its competitors. All this is done without getting the sound increased artificially.

The transition from lower-treble peaks towards the smoother foreground offers a smooth tuning environment. The laid-back lower-treble keep the sound well-boded and smooth. Furthermore, the sibilance is controlled exceptionally well, where the midrange is refined and smooth. The detail retrieval does not come close to turbulent.


Delivering natural sounds, the HiFiMan Sundara is well-balanced, slightly laid-back, and a natural headphone. Its U-shaped design offers engaging sounds that come with improved air up top and bass fullness. Moreover, it aims to provide a relaxed listen and try to engage with impactful low-end at the same time.


The open-back design and sufficient treble extension offer a spacious soundstage. The soundstage is well-rounded because of the upper bass’s high linearity to the lower-treble. Therefore, the headphone provides accurate imaging.

You should not assume a clear background and foreground distinction due to the darker middle treble. However, you can expect well-separates sound with the headphone because of it quicker decay and fine-tuning. Overall, you will get a well-metered listen with this headphone.

Should You Buy It?


Whether to buy the headphone or not depends on various factors such as the features, build quality, and personal preference. By now, you have understood how efficient the headphone is in its performance, but does it perform better than its competitors?

Let’s compare the HiFiMan Sundara with some popular headphones to help you decide which one is better.

Advanced Sound Alpha

The Advanced Sound Alpha offers a balanced but weightier sound that is less linear. Generally, both the headphones offer lightly warm mid-bass with a linear upper bass. However, Sundara has a more defined and controlled low-end.

Both the headphone deviate due to mid-range; Alpha has a quite noticeable vocal range which offers enhanced vocal clarity. On the other hand, Sundara is more natural and well-balanced with its smooth articulation and consistent build.

Sennheiser HD6XX

When it comes to clarity, the Sennheiser HD6XX is exceptionally energetic. However, Sundara provides excellent sub-bass emphasis and deeper sub-bass extension.

Though both the headphones offer slightly warm mid-bass, the HD6XX is the warmer headphone that extends its emphasis towards the upper bass. On the other hand, the Sundara comes with more definition and bass control.

The sound is natural in both the headphones, but Sennheiser is lying on the forward side, and Sundara is on the laid-back side. The soundstage of Sundara offers a significantly larger sound that culminates with extended bass to provide voluminous sound.

HiFiMan HE-560

HiFiMan HE-560 is more balanced as compared to Sundara. The bass is present and more extended, but it does not affect the sound quality, just like Sundara. Also, the headphone offers less physical impact by being more detailed and faster.

Both the headphones have a similar spacious soundstage which offers better instrument separation and precise imaging. Though they have identical mid-range, too, Sundara offers more elevation.

The distinction lies in the treble performance and upper-mids. Compared to Sundara, the HR-560 provides a sharper sounding attack due to harsher sounding. Also, Sundara prevents sibilance more compared to HE-560.

Pros and Cons


  • Detailed and fast driver
  • Excellent built with high-quality materials
  • Comfortable for long listening sessions
  • Airy and balanced sound
  • Realistic imaging and spacious soundstage
  • Excellent price-to-performance ratio


  • Treble could have been slightly more abundant
