@@thomasgeorge5159 Sorry mate, I looked for so long in so many places and couldn't find a proper replacement for my damaged headband - the rubber underpart had torn away from the plastic. I ended up just buying a padded headband cover that wrapped around the headband and zipped up.
I can't seem to find the headband either. I feel like it is impossible to get the original one, and we have to be creative like you and make our own custom headband.
@@hardwarerepair200 Even so I have no idea how will I'm going to find substitute for the broken white plastic clips inside the headband....coz they keeps the cables safe while we pull and adjust the earpieces
Hi! Nice video. It gives me the strenght to do the repair of my 400s myself. I need to change the board of the 2.5 jack. Do you know where can i find that? I did a research on the internet but i can't find that little board 😢 please help! Thanks!!!!
Yes, it is possible. You just need to desolder the old cable and solder a new one back. I have another video to teach you how to check if the cable is bad ruclips.net/video/ZaGzMXpjN4s/видео.html
Be aware its maybe not the cable, i just recived a new cable and my left side still didnt worked, the problem is in the female 2.5 jack (the cable dont touch correctly all metal parts ) now i have to put back the foams i dont have a clue how to do it its pissing me of
@@hardwarerepair200 i thought that, but the problem is that something corrosive touched the plastic and melted it, but it was just that, functional things like cables and speakers were not damaged, so I can't take it under warranty, so that's why i Asked to see if it could be something on the wires or similar
@@christianjosephalvarezrami5264 They won't replace the plastic case for you, but if it is really a problem of the wire, they will still fix the wire for you. But I don't know if their warranty terms vary from countries to countries. You better contact them first. Although I haven't faced this problem personally, the resistance of the wires might affect the audio. The resistance of the wires go up due to mechanically failure (constantly folding and unfolding the headphone). If you have access to another pair of HD400s, I suggests you to do a side by side comparison, to confirm that the bass is getting worse. As far as I know, Sennheiser counts it as functional thing.
Speaking about the silicone on the foam, you can basically skip tearing the silicone apart and just clip out the foam with silicone stil on it
You are absolutely right about it!
Yeah, the silicone is clipped to the foam plastic holder, did the thing on mine and worked with no effort
Thanks a lot for this video. I didn't found anywhere else complete tear down video and I was also having some trouble with that part in @4:00.
I was having a hard time trying to figure out 4:00 too. Glad that this video helps!
4:00 is exactly what I was looking for trying to teardown my HD450BTs. Greatly appreciated, thanks mate.

Is it possible to repair the cable? It came off the part that goes to the headphones and you can only hear it on the left side
Yes, it is possible. You just need to desolder the old cable and solder a new one back.

@@Slawko.Warwzinyak In my case it was, i bought the original replacement cable and it's working good
@@pepoeste4502 Okay okay, great then !
@@Slawko.Warwzinyak same dude, fuck this shit
My hd400s does not sound as good as when i bought it, specifically the bass, What can i do? ( I bought the headphones two months ago )
As far as I know, HD400s comes with 2 years of warranty. So your best option is to contact customer support to see if they can replace one for you.
