About this item
- Utilising a new, hi-tech diaphragm means that the diaphragm is 80% thinner than was on the HE400 series. This results in more detail, faster transients and an extended frequency response.
- New headband design offering a separate head strap which allows for the headphone weight to be spread perfectly evenly over the wearers head. It delivers both a more comfortable fit but also a more eye pleasing look.
- The all new Hybrid Headband gives a structure intended to be as practically street friendly, built to take the wear and tear of everyday life while looking great as it does it.
- The Headphone cable attachment uses the standard 3.5mm socket which gives improved connectivity and is more physically robust connector too.
- Extended Warranty: Get An Extra Three-Month Warranty

You should 100% buy another pair of cables with this if you're purchasing
Reviewed in the United States on 10 September 2020Verified Purchase
Friends - these are really amazing headphones and you should definitely get them if you're looking to spend at this price point. Nearly no other headphones will compare to the sound quality and sound stage that you'll get from these at the price point ($350 at time of purchase). With that being said, I want you to know the reason why I gave this 4 stars instead of 5:
The cable is a bottleneck.
I was lucky enough to get a cable that works, but the included cable is one that introduces noise to your sound listening experience. Do you know how long it took me to figure this out? 2 months. For 2 months, I thought that I was losing my mind hearing more harsh high frequencies than usual. I got to a point where I thought my Sennheiser Game One headset sounded better. I got to the point where I thought my DAC was going bad. Do you know what happened to me after I changed out the cable and heard the sounds that this was actually meant to produce? I cried. I cried tears of joy from the sounds I was finally able to hear. Don't be me - allow these headphones to reach their potential.
You may be thinking "if I spend $350 on a nice pair of cans, I should be getting nice cables with it." Don't worry, your expectations are well aligned with reality; however, I'm thinking about this a bit differently. If I can pay $350 to get headphones that are on par with $600 headphones, then I'm okay with HIFIMAN skimping on the manufacturing / inclusion of these cables. I paid ~$20 to get an additional pair of cables and I think you should too. Do the right thing.
Note: These are the cables I purchased:

I intentionally wanted a short cable. Feel free to research other ones and let me know if you find a better one for these.

Extremely clear audio for music and gaming
Reviewed in the United States on 8 June 2020Verified Purchase
As mentioned in the title, I bought this for casual music listening (now very regularly, because of the whole quarantine thing) and gaming. For CS and Overwatch, I can finally hear footsteps properly and know exactly where they're coming from!
Before this, I had been using the HD 598 for the past 3 years, and while they are still great, they're nowhere near the audio quality of this headphone. I'll still keep the HD 598 to use at work, since they're closed back.
Before I bought this, I tried Beyerdynamics 990/880 , Sennheiser HD 599 and the lovely HD 6XX. Unfortunately, with the exception of the 599, the other headphones would hurt my ears after about 20-30 minutes, which is why I decided to pay a little bit more and get this one.
I realize audio quality is subjective, so I'll just tell you what was important to me.
I'm using these with the Schitt Stack (modi3/magni heresy) and they sound phenomenal to my ears. I'm not an audiophile, but I do listen to .Flac songs on my pc that were either from CD rips, or Tidal. These headphones also have the widest soundstage I've ever heard. It's a bit cliché, but songs really do come alive.
Be aware that these leak out A LOT of the sound, even for open-back standards.
I could hear them playing while I was in another room in my apartment.
These are extremely comfortable headphones that I can use for hours on end with minimum adjustments, unless I'm wearing glasses, then I have to fiddle with them every 20 mins or so.
They seem to be robust enough to last a while, but because of their track record, I'll most likely be buying an extended warranty just to be safe.
I saw other people complaining about the cable, but I think the swivel action near the port is a great addition and the cable length, while relatively short, is perfect for my needs at home.
Overall, these are amazing Headphones that have made my days/nights at home more entertaining.
Wish I could try the Ananda, but they are outside of my price range.
If you can afford these headphones, go for it.
Nothing will beat it at this price point.

Fantastic upgrade from 58x and DT990
Reviewed in the United States on 14 June 2020Verified Purchase
These really are great. I had to EQ them to get the bass where I wanted it, but overall these sound very nice to listen to while providing a lot of detail. For gaming I have no issues hearing footsteps and where those footsteps are coming from. Sound stage is perfect. Not too wide, but not really narrow either.
I also have hot ears and these are just comfortable enough. Any more and I’d say they were hot but they’re perfect as they are. I normally used DT990 which have a soft velour that stays dry. The HE4XX, which I briefly had, were very hot for my ears. These are similar but somehow do it way better.

Unbeatable Value for Sound, Worrisome QC and Longevity
Reviewed in the United States on 29 October 2020Verified Purchase
HIFIMAN Sundara is regarded as one of the best value headphones under $500 category, and sound performance wise, I found that to be absolutely true. You will not find a planar headphone, or any headphones, that can bring such an authoritative technicality and elegant and lively musicality under the table for such a (relatively) low price.
Let's talk about sound. Its treble and bass is very well extended and has that fast and clear planar plucked-tightness. I can see that the treble can be a bit too peaky and bright for some people, but I personally found it to deliver just the right amount of liveliness and energy without crossing that intolerable "Beyer" level. The mids are a bit recessed and mostly flat, which I find to be a bit uninspiring, but its detail retrieval is so good that it makes up for this weakness at least a little. Speaking of which, Sundara's detail retrieval, instrument separation and imaging is exceptional. It easily competes with Hi-Fi headphones that cost over $1000 and I find that to be an unquestionable feat on HIFIMAN's part. Lastly, let's talk about soundstage. Its soundstage is not something to write home about. You will not remember Sundara for its soundstage for sure. However, it is more than adequate for enjoying most types of genre and is definitely not its weakness. It does not have an obvious blind spot, and I was generally able to pin point the direction of most instruments with ease.
Now here's the bad news. HIFIMAN has a very bad track record when it comes to quality control and the longevity of its headphones. As far as I know, the issue has been taken seriously and partially been remedied especially on their latest models such as Sundara and Ananda. However, my personal experience did not live up to my (not that high) expectation. You see, the Sundara I received has a different pads on each side. One is significantly thicker on the front with wider, but flat surface area (popularly know as old Sundara pad by the community) and the other is thinner on the front with narrower, but bulging surface area (known as stealth-revised pad by the community). Sort of a big deal since the disparity causes not only discomfort, but also channel imbalance.
And if the company can't even quality control something as so easy to identify and functionally important as putting the same pads for each side, how can I trust them on other parts that may turn out to be problematic in the long run? Then I asked myself, is it really a good value if I constantly have to fear that something will be wrong, missing and/or will probably die off in an year or two? When there are alternatives like Sennheiser HD 600 series, which admittedly may be a little behind in technicality with inherent weaknesses and strengths of old dynamic driver design, but carry impeccable track record of lasting long enough to pass them to your grand children?
In the end, I urge the readers to ask this question yourself. Imagine that, in an extreme case scenario, it is going to fail a little after 1-year warranty period. Would $349 still be a good value? If your answer to this question is yes, then I can definitely recommend this product. It will not disappoint you. My answer to this question was no, and I am returning it. I initially went with it because recent HIFIMAN's publicity gave me a bit of trust on them, which was immediately shattered when I saw the pad mismatch on my pair. I honestly though about giving 1 or 2 stars rating, but Sundara is such a good headphone sound wise, that it at least deserve 3 stars despite the lack of HIFIMAN's still awful quality control.
