Looks like a sundara cable
looks the same as the cable that comes with my Chinese version of the HE400se.
You have a Chinese version? What are your impressions? Have you managed to compare with anything?
Well, the cable that comes with it is pretty good, sound-wise not sure how it compares to the international version as I havenāt tried that out yet.
My theory is the Hifiman HE-X4 use the driver from the Chinese he400se as they both donāt use stealth magnets and appear to be very similar. I feel the 400se is a lot better for gaming than my 6xx/650 but for music, they are far too fatiguing and sound a little unnatural (also create a hotspot on my head), but the bass is pretty fun and fast on bass-heavy songs. I mainly bought them for gaming so Iām pretty happy with them for their cost (around 110usd).
For me, the he400se removes my temptations for the Sundara/Ananda as it seems to be similar in tonality.
Thank you for the info, more food for thought.
This Chinese version is very tempting in terms of price, but again all the time you want something better.

which HE400SE international(118$) or china(94$) should i get?
can only find this comparison
i asked the vendor, they said the international(stealth magnets) is easier to drive?
I remember a reviewer saying that the only difference is the stealth magnets. Basically, the Chinese 400se is the equivalent to Dropās HE-X4.
Sounds like it all comes down to what sound preference you like.

Though I donāt have the Chinese version to test, Iām guessing itās close to the 400i which is drastically easier to drive than the 400se stealth version.
Specs wise the Chinese and the international are both listed to be the same with 25 ohms and 91db sensitivity, even the listed weight of 390g. The hifiman HEx4 have the same specs but weigh 420g (most likely due to the headband).
hmmm just watched this
said theyāre pretty much the same despite the different drivers/slight measurement differences
i guess iāll get the cheaper one. since the china vers doesnāt come with that silver cable
Theyāre listed as the same because hifiman tested the original 400se Chinese version and pasted it on all their 400s. My 400se stealth measured 56 ohm

A little suggestion for those who want to purchase these: wait for a week or two (especially UK).
I purchased these with my local provider and asked them if it includes the upgraded second cable beforehand (see my post above). Received them yesterday and it was missing the second cable. Contacted the customer service and they said that adding the second cable was just a recent addition from Hifiman so if you purchase these recently, thereās a risk that youāll get sets from the previous stock with just the extremely crappy silver stock cable. Luckily, my local provider said theyāll contact Hifiman asap to send a second cable to me. (Hmmmā¦ sounds like they just manage the orders and Hifiman UK/EU ships the set accordingly)
But impressions just out of the box is FANTASTIC. I could imagine it might be sibilant for some, but personally Iām treble sensitive as well and I donāt feel any discomfort in the sound. The crispiness is just a little under the limit of feeling piercing in general (meaning there hasnāt been any tracks unbearable for me). I imagine burning in for a while would make the sound even smoother, but so far I completely love these cans!
The clarity and attack sound like a $500+ IEM, and these are just the perfect pair with my KPH30i Clears. Whereas the KPH30i CL is intimate, close, and bassy, the 400se is intimate, spacious, and crispily neutral. Iām running these off my FiiO K3 at 3 oāclock; could also do either bass boost or high gain and the cans still sound fine af. Bass boost actually makes it sound a little more v-shaped. Honestly pretty surprised that these could still run off FiiO K3 with ease.
I have a xDuoo MT-602 on its way here. Hopefully the hybrid tubes and power will turn these cans into ecstasy (it already is). 
Btw, how do folks deal with the hot spot on the dead center of the thick Hifiman headband other than Dekoni nuggets?

Extend the yokes all the way out and squeeze the headband like youāre trying to crease the center. It helps a lot. Dekoni nuggets are kind of a joke imo, just makes the fit too loose.

Just received the HE400se (China version, released in 2020 non-stealth magnets) 94$.
Build Quality
Overall the outside is fine, itās the drivers that look a little shoddy. There seems to be some oxidation on the magnets, a little brownish(rust?) hard to capture this on camera. tried to use a bit of isopropyl and a cotton swab to see if itāll come off, no dice. thereās also a tiny piece of what seems to be glue on the diaphragm. tried to nudge it off gently with a toothpick(donāt do this lol), decided to give up before i poke a hole in it. at least thereās 1 year warranty if anything goes wrong.
eq settings is from HiFiMAN HE400se - Official Headphone Model Discussion - The HEADPHONE Community
overall experience so far is great. using the eq settings above makes it less bass lean, which completes the package for me. even without eq itās still pretty good. definitely my daily driver for now, as a low-fi peasant.
using an O2 on low gain to power these, default gain resistors (2.5x low gain, 6.5x high gain). the knob stays between the 1st and 2nd notch, windows vol 100%, audio interface as dac.

pretty interesting video repairing the broken trace of these headphones
what would be the bare minimum amp for this headphone?
iāve found the douk u3 drives pretty much anything, sounds just fine and being class a drives harder to power headphones with pretty solid authority. fantastic $35 amp.
