Too soon!?
I hear ya'all!
Damn thing has not been officially released yet (released only in China at the time of writing), and here I go talking about possible modifications, I must be mad.

Intro:
Hifiman Edition XS is a new pair of headphones, resembling Ananda and Arya & of course the Edition X, which this is supposed to be a new version of.
They have Ear-Shaped cans that swallow the entire ear! it makes them ugly (to others) but comfy. no pressure on the lobes, good seal on the head (improves deep bass), and evens out pressure on the temples and the head with its larger contact area.

This is Edition X - but for the headband, they look alike.

And also it looks like its other brother HE1000.

Sound reviews
Here is my review I did not long ago.

The Mod! :
Cause & Reasoning

I described the sound as Hollow-ish on midrange, and also I felt the sound stage was so wide (in particular on my Chord Hugo2) that at times I felt the sound was out-of-phase! if you know what I mean (Google it). The centre image was a bit weak, on vocals . . . . on anything really.
Then by chance, one day I got my hand near the headphones while listening to music, and something strange happened! I had my hands near the top-front of the headphones (not touching) and the central image improved, together with some midrange lift. If I could keep my hands in a certain distance from top-front of the cans, I could almost get them to sound better - it was easy to overshoot and spoil the sound too. If you have a pair of these (I mean headphones, nothing rude) try it for yourself.
Once your hands are within inches of the back, you can influence the sound, even tune it. I believe it happens because of selective sound reflection off your palms, back into the ear.
Something else struck me too, the metal grill could ring like a bell! Try it, give one of the bars a little twang with your finger-nail and each bar rings a metalic bell sound. This couldn't be right! they are millimeters away from a large diaphragm that could take one-Watt of power. This is no IEM, the vibrations are real.
Also, if the magnet's sharp edges can create such an interference that Hifiman needs to remedy by using Srealth Magnets (rounded edges) and Audeze has the Fazor concept, not to mention Dan Clark Flow arrangement - why on earth the rear grill has such sharp edges facing the transducers ?? Parallel to the same Stealth Magnets and a tiny distance away!?
Procedure:
You have to open them I am afraid. Take extreme care!
The transducers are fragile, you can easily damage them permanently. Take note how the thing is put together, take pictures along the way to act as possible reminders. Avoid having anything magnetic nearby the strong magnets. If you don't feel confident, DON'T.
I used a small piece of thin foam at first, but it was too much, finally I settled on a layer of curtain netting, very fine and thin and in Black.
I cut a piece, with a curved shape to cover about a sixth of the area of back grill. I placed it on the dismantled back of the Alu. grill and marked the edges of the net on the grill. I used very small pieces of clear and thin Double-sided gel tape near those marks. I use gel type tape because it has no glue to smear or cure. Fumes can damage diaphragms. I carefully placed it on the inside of the grill, fixing the edges of the net with those tiny pieces of tape to the grill - last thing I want is for the piece to flap with music.
To remedy the sharp edges, I used a very fine round file (jewellers type) to carefully round off the grill edges on the inside (the outside, facing away from the diaphragms is already rounded and finished, don't touch them) . Just a little, enough to polish the edges and round them off, hardly noticeable by naked eye (my eyes).
To stop the ringing, I braced the inside of the grill, with a piece of half-round plastic bar (4mm wide), with the flat side away from the diaphragm, I used tiny pieces of same gel tape to fix the bar to the centre of the grill.
See this: (zoom in)
Edition XS-Modded.jpg


It looks a bit better than this, I used a flash to make the black net visible, otherwise the whole mod is almost invisible.

The Effect:
Very noticeable! in a good way.
The headphones are the same, but improved to my ears.
- Stereo image is much better, it is still wide and tall, but instrument pin pointing is easier, there is a defined central image and lateral solid images where before it was a bit confused. It is easier to follow the lyrics (if you know what I mean)
- Midrange is improved! is it the central image being more focused or is the midrange a bit fuller? I think both.
- There was a certain metallic tinge to mid treble, almost screaming at me at times - it is almost gone, sound is Warmer. I think it is because of the ringing of grill bars.
Incidentally after the mod. the same twang on the grill bars with my finger nail produces no ringing at all, just a dead tak.
On Classical music, violins sound warmer, no edgy sound. On Jazz, cymbals are little clearer and crisper.

You can try before you buy!
Put the same netting on the outside of the headphones without opening them, with tape, also use a round plastic bar and use tape to fix the top and bottom of it to the cans. Since the grill is curved to the outside, the bar should touch all of grill if you use tape to fix the top amd bottom, and listen - if it works for you, only then contemplate on opening the cans.

Laugh all you like! I had fun (and a little scare) and I prefer the sound.

Nice review - and nice mod idea! I do agree to what you said overall, and yes - that ringing off the grill sure is there!
Appreciate your idea though, that's smart - and I'm sure that tones down the ringing! I'll try this one...

Happy listening!

Here, problem solved!
A soft piece of leather, a bit of double sided tape, that'll do it.
Steadier, non-slip, stays on my head without tightening the spring.

I was waiting for some solution to this, was just drafting a headband sleeve question on hifiguides - thanks! I'll keep this in mind as well. Looks well executed - could be a bit more aesthetic though, or maybe its just the pictures.

Cleaned up afterwards!
But it is more steady, shaking my head gently forward and back proves it.

How exactly you got the strip taped on? I got a pair of 400i that are sitting around doing nothing atm, maybe I can hijack the sling from them

Sorry for late reply.
The standard leather band from Hifiman is a little too thick to be used here.
The side plastic ends on EDX are very tightly inserted and the have a catch mechanism too.
If not careful you can break them, hence the thin strip of leather I used (from an old lamb leather jacket).
you need to use a flat metal pry tool to gently slide the end plastic hubs down , they are tight and have locking catches on the sides.
once they are slid down, you attach the leather to existing fixture using the thinnest double sided tape to stay put while you carefully slide the hubs back up. Its going to be a very tight squeeze , take your time and be careful.
the tightness and the tape will hold it, mine hasn't moved yet.
Mine in use is only a centimeter or two lower than foam headband.
1 - it makes the whole thing more manageable as EDX do not have much headband springiness and earcups are long, so the strip lifts the whole thing up a bit.
2 - gravity and the leather add to the spring and pull the cups inward. (see middle picture)
3 - the leather on my head does not sweat, pressure is spread across a larger area.
4- also the suede side on my bald head doesn't slide , so can rock away and the headphones stay put!

I was hoping the sling from my 400i was a clamp on, but turns out they slide up from the bottom of the arms, so dissassembling the 400i to get it is starting to reek of effort.
I do like the concept, but I might have to hold out and see if I can get an OG HEX headband to swap - although it sound like removing the EditionXS earcup is far more complicated than the HEX earcups - and with my luck something will break
The A2C has a simple leather sling - no padding or anything, and I was surpised at how well it worked. Not hot, itchy or anything

The bolts that hold the yokes to the cups have a barrel-nut on the inside that has glue in the threads. It won't come apart unless you break it.
So getting the yokes off is a NO.
Also the EDX has a little swivel on the yokes for a better seal that Editions don't (to my knowledge).
That's why I chose this method.

If you have a pair of these (I mean headphones, nothing rude) try it for yourself.
Once your hands are within inches of the back, you can influence the sound, even tune it. I believe it happens because of selective sound reflection off your palms, back into the ear.
Something else struck me too, the metal grill could ring like a bell! Try it, give one of the bars a little twang with your finger-nail and each bar rings a metalic bell sound. This couldn't be right! they are millimeters away from a large diaphragm that could take one-Watt of power. This is no IEM, the vibrations are real.
Also, if the magnet's sharp edges can create such an interference that Hifiman needs to remedy by using Srealth Magnets (rounded edges) and Audeze has the Fazor concept, not to mention Dan Clark Flow arrangement - why on earth the rear grill has such sharp edges facing the transducers ??

Hi. Haven't done much on the long cup HFM's I only own the HEX v2. But I've done lots on round cups. Those experience says get an 80% empty mesh or or no back screen at all. It also says the fuzzor mod is very important on the 6 and 500 and of some good use on the 6SE.

Removing the back of my HEX would be too severe. there seems to be too much area not to have some screen protection. I would measure the distance from the driver to back of the screen. If enough i'll install thin felt/glue strip like the fuzzor mod. Next thing I'll do to cut lower freq reverb which I've done on all my other cans including the HD-600 by placing dynamat ( not as effective as sorbothane but sticks much better and is a lot cheaper). In/around the cans or even on the headband. Those vibrations are a-musical. Can always EQ in lower bass to make up for perceived shortfall. It'll be much faster with less overhang.

I will work on this tonight and report back

I'm back. Hold your horses. Firstly the HEX v2 is not the XS I'm going there with my findings.

1. The rear grill cannot be taken off the back. See Pic at end. Also the grill tmaterial is magnetized.


2. The internal wires are very thin. Watch it.

3. When taking screws from the front put a cutout (cardboard) or saran wrap to cover the Mylar. Finish unscrewing by hand.

4. This item is built on a better scale than the round cup models.

5. There is no way to get felt on the back of the grilles. The material doesn't cut well that thin. There is paint that absorbs sound, that might work. I have this super sticky tape that absorbs vibrations but I wouldn't expose the drivers to that stuff they would never disconnect. A great but ugly solution would be to put the tape on the outside of the grill bars then cut the felt so it would wrap around and meet on backside. But it would look like wooly catepillars attacking your headphones

I think the metal headpiece vibrates. I'd put dynamat on that. Perhaps .5" x 1.5" on each side would do

I hate the small diameter and flimsy appearance of the input clips ( not issue on XS) so I may get some 22 GA wire and a new input. If so solder spatter or heat can ruin the drivers. Cover with cardboard cutout and use a radiator were cable goes into the driver. Watch polarity

Hang onto the black back screening material. It's worthwhile.

OK notes from the under ground over and out. See Summit Go HFM Edition X for further info when I have it
