thatâs exactly what I was planing on getting and thatâs why I asked.
Thanks for the Infos will order one of those headbands
So as you can see it fits nice.
All I had to do was to drill the holes a bit bigger, so the the little plastic pegs fit into then:
then you can use the original screws.
Itâs quite comfy.

I really like the look of this clearcoat silver honeycomb grille on the silver he400 se so I left the ring off and glued it on

Added silver Beyer pads on this - looks cool, comfortable and sounds clear and open - liking it! I didnt use the sound attenuation pad from the Beyer, reused the ring with mesh backing from the original hifiman pad (had to trim maybe a milimeter off the edge around the hifiman ring to make this beyer pad fit)

Any impressions youâre down to share on sound quality and comfort changes? Aesthetically, theyâre definitely cool! 
Comfort wise, I really like the Beyer pads, they are a bit stiffer but less clamp, takes some edge off the highs, very smooth and bass is still present but comfortable. To me this setup feels more clear, smooth and detailed and larger open stage despite being padded.
The Beyer pads are soft but feel stiffer and more present and a bit more premium than hifiman pads, the material itself to me feels a bit less cheap⊠more like a senheiser hd600 feel⊠they are lower profile reducing the compression a bit (the Beyer pads are more like a ring, whereas the Hifimans are soft âtapered tubesâ so the Beyers are a bit more like a round velvet pillow cushion feel - if you have ever worn a Beyer headphone you know the feeling, they are round rings). Clamp is actually reduced a bit and they feel lightweight, but on my head its not loose or anything, feels great - you cannot hear any foam movement at all⊠If shaking the head, Beyers are just super soft with no microphonics, I dont feel its too loose, to me it feels a bit more premium. So reduces clamp, feels soft and more premium but slightly stifferâŠ
The final setup combination I have - with the honeycomb grille and no mesh on outside, and on inside just the original interior hifiman mesh (no beyer foam attenuation foam) and with the round velvet beyer pads to my ears increases soundstage and is super open (without the foam I can look right through the headphone) and takes a bit off the highs and is more detailed, bass is the same imho - I tried with the sound attenuation foam included but I found without the foam it sounds more open and detailed, and not at all harsh⊠I have never found the HE400 se to be excessively bright but I do think the Beyers do soften the highs a bit and sound feels refined and precise yet smoothâŠ
The stage sounds bigger with the honeycomb grille and totally open with increased detail to my ears and clear but at same time the Beyer makes it a bit smooth and a bit less metalic sound than I think hifimans can sometimes have - like the room got larger but walls got a bit padded like now youâre in a carpetted concert theater?

Sounds like you have a winning combo on your hands. I donât have the HE400se, but I think I might give these a shot on my HE400i and see how it goes. I love pad rolling!

Here is what I mean by totally open without any foam - I left out anything except the one layer on inside which is the thin mesh just so my ear cannot direct contact the driver⊠On this headphone I actually dont find that this makes it at all harsh or too bright, it just opens it up and I feel the Beyer pad does a good job taking just enough of edge off the highs to make it smoother but sounding comfortable but still detailed:

My test for whether a headphone is too bright: Adele Rolling in the Deep⊠That track has a couple intensely loud and piercing vocal moments where she can seriously blow your ear drums out on the wrong headphones 
but I dont get that here so its all good

I donât own the HE400SEs, but I do own quite a few other round cup models so Iâm gonna snag a couple pairs to experiment with. It looks like theyâre basically trying to accomplish the fuzzor, waveguide, and grill mods with a single installable piece. I, personally, havenât found the waveguides to make any noticeable difference on the two models I tried it on (HE6 and HE400i), but itâll be interesting to see what the cumulative effect of all this is.
Sorry if this was posted elsewhere, but is there a surefire way to know which 400SE you bought? The Stealth Magnet version goes for the usual price here in South Korea, around 100 usd, but one of their online retailers started selling a 400SE for about 50 usd. Reviews said it was legit, but the non stealth version? Some claim it may be one specifically for the asian market, but why would it be cheaper is unclear. Mine came with a black cable [nice one actually], different from the cables I see in reviews. Anyway, mine sounds great, but I am curious as to what I actually bought!
If its the 400SE then its the stealth magnet version (SE means stealth edition), the 400i is slightly different and have the none-stealth drivers, the price reduction is probably access inventory that has been sitting around that they just want to get rid of

I have the 4xx and 400se and love them both, but the 400se is definitely superior. as soon as I order some replacement pads, Iâm giving my brother-in-law the 4xx for his gaming setup.
Yes, that is what I thought as well at the timeâit was quite confusing.
But I did some digging elsewhere and found a reddit post on this eventually. There is a different variant being sold in Asia, where I got it, and the international version. Reddit - Dive into anything
The OP did quite a good job comparing the two, and basically the Asian {China} version has a more relaxed treble, but everything else seems the same except for the black cable I got with mine. His pics show the same black cable, so I can only assume I got the Asian version. The box I got with mine is different though.
Unless the dude took accurate measurements (with a proper rig) or took apart the headphone and actually saw a physical difference between the two iâd still its the stealth magnet version, i difference that stubble can be attributed to a few things
- OP could just be âhearing a differenceâ where there isnt one
- unit to unit variation
- different production batch, china probably had an earlier version which would explain the different cable (after realizing they could get away with a cheaper cable they went international with it)
even something like a different pad internally could cause a difference that small at the end of the day it doesnât really matter, enjoy the headphone and dont worry about it
P.S i dont trust the OP of the post just because he say the sound is better on the 400se than sundara. I personally find the Sundara is a very different headphone in term of tuning so aside from a mention because they are both open back and both from hifiman the two should not be compared
Thanks I will enjoy, though it bothers me because it is kind of unnerving what Hifiman accomplished at the 50-100$ mark.
True, I agree, it could easily be any of those things to account for differences he heard.
I wonder if there are tariffs on electronics for anything from China coming to the States. We have those in Korea, and it can add 20-40% on to most prices. That might explain the pricing more than anything.
