Really appreciate @ksorota 's help, his informative guide made a noob completed his caps mod! I'm not good at finding the differences, describing it could be more difficult, anyway I'll try my best, in my way. Note that I've only got 30 hours of burn-in, so it could sound better, but I don't...

Sorry, a noob's got finger-itchy now. I'm not in US so I think I can only do it myself. So... From my observation, it's like replacing all of the three big caps with even bigger ones and the medium one in the middle? Maybe not too hard for a noob like me?

Based on your description, I think the back of the headphones is like anodized aluminum? not covered by paint? especially look at the silver parts, there are like corroded... Honestly I guess that pair I showed might used some non-original parts, since people could steal some parts out of the...

I took a second look a the picture, and I just realized the headphones that guy has might not be legit, they look weird (yes, I'm in China, where things can be more dodgy). And the pictures are kinda gross, but since you wanted to see...

It's just the black layer on the back of drivers. Sorry I haven't bought SEM5 so I don't know what material it is exactly. Honestly, since no one mentioned this (could-be-obvious) problem here, and according to your and Sonic Defender's reply, I think SEM5s are fine. Maybe the user on my local...

Hi, I saw complaint on my local forum about the paint on used SEM5s starts to come off, due to "oxidizing" or things. Does that happens to any of your SEM5s? I hope it's just a defective unit...

Is it? I don't know, I thought it was from US... But anyway, I can't find any Brainwavz pads on Chinese website so...

Is possible to use earpads from Hifiman on these headphones? Since I'm in China and it's not easy to get those Brainwavz or Lawton pads, while Hifiman pads can be bought conveniently, Hifiman's pads could be my only choice to play with these headphones...

I just got my K7XX for a few days (I'm in China and I used forwarding service)and I really love these headphones! I own a pair of Fidelio X1, and I liked them, but now I use K7XX only.   I'm not professional on listening, I find the K7XX sound "clear and accurate" on pop and rock, while X1...

I just read the comments on Massdrop and Hicks12 in UK got the headphones, with no import charge! There's the link: https://www.massdrop.com/buy/akg-k7xx-massdrop-first-edition-headphones on page 152.

Thanks! I nearly forget about that! Thanks for mentioning that! But I still don't know how to open it...

Thank you so much! I listened carefully just now, the "buzz" on the left side is more like some electrical noise, not physical, it's like some kind of electrical touch. I've heard it before, perhaps it's in the radio, when the signal was not strong, but not the white noise. And I found the thin...

I bought a second-hand HD565 whose sound goes to the right around 20%, But I really love the sound! Then when I was wondering whether I need to get the left driver changed, I saw a couple of HD535's drivers on ebay, do they fit HD565? Maybe I can fix my HD565 with them. And the sound of my...
