i posted that in other thread but it is worth posting here for somebody who wants to improve the HE400i 2020
for those pads you need to purchase also plastic hifiman rings that are around 4$ on ali
here is a link for the pads - https://www.aliexpress.com/item/100...earchweb0_0,searchweb201602_,searchweb201603_

changes

1 - addressing the 8khz peak
2 - providing better sealed front volume that gives additional pressure to the low bass
3 - much deeper sound stage because the driver is further from the ear and the pads have larger opening
4 - better imaging because of the point number 3
the pads are for Fostex th900, 105mm wide, the plastic hifiman rings fit perfect inside those pads

How is quality control on these headphones? I've had to return 2 Sennheiser HD 560s due to lose screws that won't tighten but I've also heard bad things about hifiman QC. Has it improved any ?

I haven't seen this issue anywhere else but I did have an issue with my 400i 2020. One of the screws that connects the right cup popped out one day. It took a couple of months and a bunch of follow up but Hifiman did get me a new screw that is staying in place.

I have some 560s arriving today but the open box deal on these right now is unbeatable. i think i have to try them out

 

[TomD]

Does anyone here own both the 560s and 400i 2020? I'd be interested to know which one you think sounds better

 

[Sebaldian]

just ordered some (only 139 open box on hifiman site) and will have both them and the 560s to try out back to back in about 2 weeks

I recently purchased the Hifiman 400i 2020 and they should be here tomorrow (an open box set off their website as mentioned above). While this is not my first experience with planar cans, I am none the less excited. The mobius was my first taste of planar and I loved them but their build is horrible. Kept breaking in the same spot. I digress. I was ultimately wondering if the EVGA Nu Audio sound card (their original one, linked for specs. scroll down the page some) would be enough to push the 400i's? I got the card when I was building my current PC in preparation and anticipation of getting into the headphone hobby after getting my taste with the mobius.

I received my HD 400i 2020. Finding the earpads to be rather itchy... Anyone else had this issue ?

Not while I used them. They were too small for my ears so I've replaced them with ZMF Ori pads - very nice.

Are you in the UK by any chance? When I type ZMF Ori pads in to Amazon I get many different listings, but I would really like to change the pads. Does it make the sound worse by doing this?

I found the pads itchy at first but got way better over time somehow (maybe the felt packed down a bit or I simply got used to it)

I found them kind of itchy too. And too small. I ended up getting the ZMF Auteur pads, which are so much more comfortable.

No, I'm in the US. The sound does not seem negatively affected to me, very much the same, if not better. I had to fiddle constantly with the original pads for a decent fit and sound.

As for the pads, I went direct to ZMF - https://shop.zmfheadphones.com/collections/pads/products/ori-pads

I think my unit has a bit of driver imbalance; the left side is a bit quieter than the right. I don't feel like going through the hassle of getting a replacement so I guess I'll just adjust the balance with EQ.

Just 8 pages? This headphone is the best in the 400 line hifiman has ever made.
Not recommended to use out of a smartphone, the more power the better! They scale very good with dedicated desktop amps and if available xlr balanced. This phone is a great surprise and the best HE400i ever beeing built till now.
