Some of the key innovations Hifiman originally brought into the HE400 series are retained in Sundara’s design. It does not look “unlike” a Hifiman headphone with its logo prominently on the side of the headband and the use of the Focus A detachable pads. From the outset, the build quality of the Sundara is leaps and bounds above that of the HE400se. While the overall shape of the headphone is the same, the Sundara has a full metal build that feels substantial in hand. Here we get a large leather suspension strap that spreads out the weight of the Sundara over a wide area to minimize pressure spots. As such, I find the Sundara to be very comfortable, moreso than the HE400se. The pads of the Sundara are a perforated fabric/pleather mix that’s soft to the touch. The metal connection between the yokes and the cups is significantly more robust than the HE400se’s plastic to metal approach. I don’t expect any snapped cups here unless a user is careless with setting them down after use. This is part two of review series where I will look at the HiFiMan HE400se, Sundara, and Ananda. Stay tuned for the final installment with the Ananda!

HiFiMan Sundara - Review 2023 - PCMag UK

Right around the second iteration of the Sundara, something changed with the headband manufacturing and I think it was particularly with the steel spring section of the headband assembly. I had the first Sundara version plus the second version and the clamping force was increased on the second version. The extended guitar section by Don Felder and Joe Walsh was simply marvelous. It was bright yet not fatiguing and as clean as I have ever heard it. The auxiliary instruments all sounded like they surrounded the guitars and built upon each other. One thing I noticed was that the Sundara struggled to fully give the spotlight to the guitars and instead had many of the other instruments encroaching in with similar loudness and impact.

Mid-way through, the sounds of angelic entities intrude on the primary act. Impeccable is one word to describe the sweet and delicate sound required to reproduce it. With most headphones, the delicateness is not reproducible or will have latent elements of ghosting in the speed. This can be heard with a slightly lagging reverb accompanied by extra distortion and noise. The Sundaras were effortless and transparent without any added distortion. I prefer names, to be honest, and it is not the first time Hifiman has done this with the Susvara and the soon-to-be-launched Ananda being the other noteworthy named headphones. What Is The Pitch? Names Not Numbers I do live the “if it isn’t broke don’t fix it“ rule, but I always give thanks to all the pioneers for pushing the envelope on our behalf. Like the HE400se, the Sundara’s bass tuning is the same most of the HiFiMan headphones. Flat. Needless to say, there is not a hint of bloat or mud on this headphone. Unlike the HE400se however, the bass of the Sundara sounds fuller with more depth to it. I would not call the Sundara anemic in any way. Bass has a nice sense of slam, control, and resolution, so-called “planar bass” if you will. Though there is a slight roll-off at the very lowest octaves, rumble is plenty present. It’s quite a bit better than the HE400se but do I get the feeling that there’s some performance still to be found. Perhaps in the Ananda. Mids Gone are the elaborate display cases of the HE series such as the wood of the HE560 and the faux leather of the HE400i. In part, I guess it saves a little on budget costs for the project and more on the headphones but I do miss those cases a little.

HiFiMan Sundara review - SoundGuys

I think comfort is more attributed to the new pad design which has the same sized 100mm round shape but it seems much softer and moldable. Whilst the headband is radically changed in functionality and materials it still sports a split metal design at the top and both still use a pressure displacement secondary strap below the metal headband arch. The Sundara I will be reviewing today is the 2020 model. There is some confusion around whether or not there is a new, different 2021 model. I reached out to HiFiMan support and as it turns out, there’s actually no other version of the Sundara. What’s in the Box? As part of that neutral bright tuning, there is a good helping of lower treble energy on the Sundara. Yes, it does get sibilant at times and yes, certain notes have a piercing quality to them. But note that this is different from the 7 kHz peak on the HE400se that’s clearly prevalent. On the Sundara, it’s a general spiciness without a specific culprit. I personally don’t think this is an issue but if you’re especially sensitive to treble it is a point of caution. While I like the Sundara’s treble as it continues the lively, energetic sound of the mids, there is a brittleness the timbre that’s noticeable on the hats and cymbals. It can be a little immersion ruining when it appears. Not a deal breaker for the Sundara as a whole but it does diminish the experience for me. Presentation Instead, Hifiman has elected to continue with the HE400S box-type design which they have been using for a while now on their budget models though with a nicer satin-type finish on the inside to create a case-like effect.As you have tested both Vali and Sundara, do you think that Sundara would be a nice complement to the Vali ? Or the Vali is superior and the Sundara would not bring anything ?

You do however get a feeling of a much more rigid headphone on your head. However, the Focus A pads and the headband strap do a good job of softening up the grip and dispersing pressure in a balanced manner making the Sundara a more than comfortable fit. In one of our previous writeups, particularly the Edition XS review, we casually mentioned within the comparison section the thought-provoking possibility of a Sundara Stealth Edition. The Sundara is not just an iterative upgrade on either though. Hifiman is pitching two key areas that I think will resonate with Hifiman fans; build and sound quality. All of this is wrapped around the phrase “beautiful” which is the literaltranslation of the word Sundara (Sanskrit).The headband still has a leather adjustment strap underneath for pressure displacement and comfort. You can adjust the height of the band as a whole via a notch system on both sides of the band. The materials of the strap have slightly changed now with a faux leather finish. It has been 3 years since Hifiman last focused on its entry-level or mid-fi range of planar headphones.
