Defean SUNDARA Replacement Earpad Velvet Leatherette and Soft Foam Ear Pads Compatible with Hifiman SUNDARA HE400 HE400SE 400I 400S HE560 560I HE500 300 350 HE3 5 6 Headphones

I delayed getting replacement pads for my HE 400i headphones for a long time after the original HiFiMan set fell apart, mainly because people in reviews indicated that they'd be difficult to switch out. I found it incredibly easy to pop the original set off and pop these perfectly-sized replacements into the tabs. It might have been the easiest earpad replacement I've ever done. I didn't notice any improvement or degradation of the sound quality between the old and new set of ear pads. They seemed to pretty much be a 1:1 replacement. They are thick and comfortable. I have no idea whether they'll last, but I doubt it's possible that they could fall apart faster than the HiFiMan originals did, so I consider this a win. I am very happy with the quality of these replacements.

feels pretty sturdy, i wish they were a little thinner and foam less firm

Medium-high quality replacement pads, would get again if or when needed. Similar fit and comfort to the original pads.

fell apart after a couple months of use. total garbage

Es un buen producto, se ajusta perfectamente a los auriculares y debes prestar atención en su instalación y ajuste ( hay video ilustrativo en YouTube) es suave al tacto y cubre totalmente la súper de los oídos para una escucha agradable. Los recomiendo.

These fell apart after about 7 months unlike the stock pads that only needed replacing due to excess squish. I had to go back to my original pads because these have unglued and completely failed. The sound signature change was slight but notable and while back to back is hard to test, I do think I prefer the sound of the original pads.

After a few years of heavy use the pads on my HE-5SE started to blow up and disintegrate pretty badly while I was in the middle of editing a large video project. I tried to fix them with spray adhesive but it turned into a chore. With Prime I could get these in about 36 hours, so I pulled the trigger. Price was right. Overall the material quality feels pretty identical to the HiFiMan pads. For the most part you could put these next to the same style HiFiMan pads and you would be hard-pressed to spot the difference. The faux leather is nice, the foam is just firm enough, and they seems just about as un-sturdy as the HiFiMan equivalent! As a few others mentioned, they sucked a fair bit to install -- certainly harder than the original HiFiMan pads. Because the backing is plastic you run the risk of bending them if you push too hard (scary) and I wound up swearing a fair bit trying to get them on. No sooner would I get two tabs in than another would pop out. Very frustrating, but I guess you pay for a bit of the price discrepancy with sweat equity. I would totally buy again in the future though -- good enough for me, no real impact on sound, if anything they restored the "space" and sound stage a bit by moving the cans back away from my ears (my old pads compressed a lot more because they were heavily used).

It works as specified.

La única pega que les pongo es que venían en una bolsa sin instrucciones de ningún tipo… y no son fáciles de poner bien en los auriculares. En mi caso eran para unos Hifiman HE560. Por lo demás… a priori no se distinguen de los originales.

My earlier replacement pads of another brand has its faux leather peeled off badly after about 1 year of usage. So i bought this as replacement. Hopefully this new replacement can last much longer. This replacement pad is easier to installed than the my earlier pads but its still quite fragile...so be gentle during installation else you may break the mounting brackets. Fitting : The outer and inner diameter matches the earphone well and fitting is no issue. Audio Performance: Sounds exactly like the original pads. No issue with sound performance.

Failed in less than a year, like any polyurethane fake leather. Pieces everywhere.

Very comfortable, as good if not better than originals. Took 1 minute to remove the originals and put them on. I highly recommend after one month of use
