Ideal for
Indoor Use

Open-Back Design

Headphones with an open-back design, allow air to pass through the earcups. This means that Open-Backs do not block any noise from around you, as closed-backs do, and music being heard will also leak outside to people around you. So they can only be heard in a quiet environment.

However, Open-back headphones do sound more natural and open. Open-back headphones create a feeling of space, presenting audio as if you are sitting at a live concert. Audiophiles swear by open-back headphones, and they sound quite different to closed-backs.

These headphones are perfect for critical listening sessions, mixing and mastering music. They have an accurate soundstage presentation and precise imaging.

Planar Magnetic Drivers

Planar magnetic drivers combine characteristics of several driver types. They employ magnetic fields akin to dynamic and balanced armature drivers. However, planar magnetic drivers, like electrostatic drivers, use a flat, thin diaphragm in contrast to a coil. The planar drivers are known for their quick transient response.

Replaceable Cables

A pair of headphones with a replaceable cable has many benefits, and one of them is if the connecting cable has a problem, it doesn’t mean that you have to buy a new one. If the connecting cable gets pulled or damaged, you can replace it and keep using your good-old headphones or IEMs. This way, your headphones will be protected and will last longer. With the advancements in cable manufacturing, you now get a variety of replacement cables with various termination options, lengths and quality.

I'd be lying if I said, I'm not a little biased towards Planar Magnetic headphones. HiFiMAN has managed to make great sound more accessible to the masses with the HE400se.

Byakugan X.S. (Gurgaon)
A very good sounding headphone, but that is it.

A layman's review of the HE400se also a little heads up on things i found out after using the headphones

Full TL;DR-The only amazing thing is their sound quality(id give 6damn stars if I could) and comfort, everything else is sub-par or shit

1) They will sound terrible on mobile phones , even flagships like the samsung galaxy note10 , the macbook air 2017 is also not enough for youtube/spotify, if you have a gaming laptop it might just be able to power these(Youtube/Spotify will still sound a bit underwhelming)

TL;DR: Get a DAC+AMP-Shanling UA2, Fiio BTR5,Fiio E10k(8year old model) are some relatively cheap recommendations

2)They will sound "bad" right out of the box , burn is a real thing and these require some burn in (mine are approx 25hr-burn in done) they will get a bit louder , more clear , spacious and accurate the more you listen to them

TL;DR: Burn in is required

3)Another reviewer said the build quality is bad , he is right it is shit , cheap earcups(not earpads, mind you) , grills and what stands out the most is the cable , in Hindi we have a word "Tangna" , its a metallic wire used to dry clothes , the cable is basically that , but thinner and there are 4 of them, its an absolute joke. Also they are very fragile, their weight does not match with the build quality DO NOT DROP THEM. Do not press them hard on your head, it will sound like crackling chocolate wrapper and that is because the diaphragm is as thin as a plastic wrapper and fragile so , it might tear the diaphragm, they're comfortable though, nice earpads but they will heat your ears during the summers

TL;DR: Build quality not the best + they're fragile

4) THEY ARE OPEN BACK they leak a LOT of sound ,and dont isolate at all , even at 10 volume they leak enough sound that its audible by people in the room .Also they're full size headphones so they are humongous, by normal headphone standards.
TL;DR: Thyre not portable headphones

5)The packaging is meh , but one good thing is the number of authenticity seals , there should be 2(top and bottom) on the headphone box and one on the cardboard box.

Sound quality review:
go to headfi.org , they have more expertise than me in terms of sound ,
They sound phenomenal absolutely phenomenal , hence the 5stars, but one thing though you will not "feel" the bass you will "hear" it.

Shipping/Customer service :
It was impressive the headphones arrived in 5 days(3 Business days) to Delhi , no hiccups whatsoever .

We thank you for this lovely review & we are glad you are enjoying it! Keep the music playing.

Great entry level audiophile headphones

I'll preface the review by saying that this pair sounds like a completely different set of headphones after burning in. When I first got them I was not at all happy with the performance but I held off on the review for about 20 hours of listening and boy was it worth. With every passing hour these got better, and by the time I hit the 20 hour mark, the headphones exceeded my expectations.

Physically, the headphones are built really solid. The earcups are as comfortable as can be. You can listen to it for hours without a hitch. Putting them on for the first time, they feel underwhelming. It takes some time to get going but once it does the sound is amazing. The mids are crisp, the bass is just the right amount of punch and the soundstage is extremely wide. The imaging is so good that you can almost imagine yourself sitting in a theatre listening to Beethoven. Adding to that, the headphones are pretty easy to drive. I have reasonably high end laptop and phone. Both of them could drive this pair easily. Although I'm looking forward to a DAC to further improve the experience (have my eyes on the Zen Dac V2).

Unfortunately these headphones aren't without flaw. The accompanying wires are absolutely abysmal but fortunately they can be easily replaced. Another piece of equipment I have my eyes on. And finally Hifiman infamous for its QC did mess up one thing. The left earcups are just a tad bit quieter than the right. Initially I thought it was just me but everyone who tried this pair agreed. Although easily corrected with a little EQ balancing, it's not something one excepts from a new pair of headphones. This might also be rectified with the new set of wires but until then any device without a balancer can't be used with these headphones.

Hey, thanks for taking time and sharing this wonderful feedback. We welcome you to talk to our Headphone Gurus for selecting the right cable for your headphones. They will be happy to assist you!

Good sound quality though disappointed with soundstage

This is my first experience with open back (or planar) headphone. Note that this is the international 'Stealth Magnet' edition.
The sound quality is good - bass is controlled and not muddy (though there is not too much of it). Mids are good. Treble is also nice.
The cable is horrendous though - not so much in terms of sound quality , but it is stiff and has quite a bit of microphonics if you move.
One thing I was quite disappointed about though was sounstsge, or the lack of it. I was especting a wide soundstage with atleast some depth. Unfortunately, it still seems that sound is coming from within the head rather than outside. Similarly, I did not find imaging to be any more accurate or different from a good closed back headphone. I have tried driving it from mobile and two different laptops. I will report back if a dedicated DAC/Amp changes that.
Comfort wise, the pads are nice and comfortable. The headband will take a whole to break in as it still feels uncomfortable when listening for more than an hour...
Buying experience and delivery was fast from Headphonezone.
